We're dividing 66073708 by 170 
We want to divide 66073708 by 170.

On to step 1:
The number 170 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 170

Advancing to step 2:
When dividing 66 by 170, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 170

On to step 3:
The number 170 fits into 660 3 times, leaving a remainder of 150.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 510 from 660, we get 150.
Fetch the next digit (7) from the dividend, attach it to 150 and continue: 1507 / 170

On to step 4:
When dividing 1507 by 170, we get 8 with a remainder of 147.
Write down 8 as next digit of the result. 
Result so far: 38.0
The remainder is 147 after subtracting 1360 from 1507.
Grab the next digit (3) from the dividend, add it to 147, then carry on: 1473 / 170

Advancing to step 5:
170 can be fit into 1473 8 times, resulting in a remainder of 113.
Record the quotient 8 as the next digit in the result. 
Result so far: 388.0
If we subtract 1360 from 1473, we get 113.
Grab the next digit (7) from the dividend, add it to 113, then carry on: 1137 / 170

Let's proceed to step 6:
170 can be fit into 1137 6 times, resulting in a remainder of 117.
The next digit of our result is 6. 
Result so far: 3886.0
If we subtract 1020 from 1137, we get 117.
Fetch the next digit (0) from the dividend, attach it to 117 and continue: 1170 / 170

Let's proceed to step 7:
When dividing 1170 by 170, we get 6 with a remainder of 150.
The number 6 becomes the next digit in our result. 
Result so far: 38866.0
The remainder is 150 after subtracting 1020 from 1170.
Include the next digit (8) from the dividend after 150, then repeat: 1508 / 170

On to step 8:
When dividing 1508 by 170, we get 8 with a remainder of 148.
Put 8 as the next digit of the answer. 
Result so far: 388668.0
Subtract 1360 from 1508 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 9:
If we divide 1480 by 170, we get 8 and a remainder of 120.
The next digit of our result is 8. 
Result so far: 388668.8
Deduct 1360 from 1480 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
If we divide 1200 by 170, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 388668.87
Subtract 1190 from 1200 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
When dividing 100 by 170, we get 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 388668.87
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 12:
170 can be fit into 1000 5 times, resulting in a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 388668.8705
Subtract 850 from 1000 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
1500 divided by 170 is 8 with a remainder of 140.
The next digit of our result is 8. 
Result so far: 388668.87058
If we take 1360 away from 1500, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 14:
If we divide 1400 by 170, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 388668.870588
Deduct 1360 from 1400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 388668.870588 and a remainder of 4e-06.
