We look at the division of 66710150 by 173 
We're looking to find how many times 173 goes into 66710150.

Advancing to step 1:
If we divide 6 by 173, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 173

Advancing to step 2:
The number 173 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 173

On to step 3:
173 goes into 667 3 times with a remainder of 148.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 519 from 667 and we're left with 148.
Append the next digit (1) from the dividend to 148 and continue with: 1481 / 173

On to step 4:
173 can be fit into 1481 8 times, resulting in a remainder of 97.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 97 after subtracting 1384 from 1481.
Grab the next digit (0) from the dividend, add it to 97, then carry on: 970 / 173

Going ahead to step 5:
When dividing 970 by 173, we get 5 with a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 385.0
The remainder is 105 after subtracting 865 from 970.
Take the next digit (1) from the dividend and append it to 105, then repeat: 1051 / 173

Going ahead to step 6:
When dividing 1051 by 173, we get 6 with a remainder of 13.
The next digit of our result is 6. 
Result so far: 3856.0
The remainder is 13 after subtracting 1038 from 1051.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 173

Step 7:
135 divided by 173 is 0 with a remainder of 135.
Write down 0 as next digit of the result. 
Result so far: 38560.0
Subtracting 0 from 135 leaves us with 135.
Append the next digit (0) from the dividend to 135 and continue with: 1350 / 173

Let's proceed to step 8:
173 can be fit into 1350 7 times, resulting in a remainder of 139.
The number 7 becomes the next digit in our result. 
Result so far: 385607.0
The remainder is 139 after subtracting 1211 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 9:
When dividing 1390 by 173, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 385607.8
If we subtract 1384 from 1390, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
173 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 385607.8
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
173 can be fit into 600 3 times, resulting in a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 385607.803
The remainder is 81 after subtracting 519 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 12:
The number 173 fits into 810 4 times, leaving a remainder of 118.
Record the quotient 4 as the next digit in the result. 
Result so far: 385607.8034
If we take 692 away from 810, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 13:
The number 173 fits into 1180 6 times, leaving a remainder of 142.
Write down 6 as next digit of the result. 
Result so far: 385607.80346
Deduct 1038 from 1180 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 14:
173 can be fit into 1420 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 385607.803468
Subtracting 1384 from 1420 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 15:
173 can be fit into 360 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 385607.8034682
Subtract 346 from 360 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 16:
The number 173 fits into 140 0 times, leaving a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 385607.8034682
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 385607.8034682 and a remainder of 1.4e-07.
