We're dividing 170156 by 66 
We want to figure out the number of times 170156 can be divided by 66.

Advancing to step 1:
1 divided by 66 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 66

Advancing to step 2:
66 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 66

On to step 3:
The number 66 fits into 170 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 132 from 170 and we're left with 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 66

Moving on to step 4:
The number 66 fits into 381 5 times, leaving a remainder of 51.
The next digit of our result is 5. 
Result so far: 25.0
Subtracting 330 from 381 leaves us with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 66

Moving on to step 5:
66 goes into 515 7 times with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 257.0
The remainder is 53 after subtracting 462 from 515.
Take the next digit (6) from the dividend and append it to 53, then repeat: 536 / 66

Advancing to step 6:
If we divide 536 by 66, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 2578.0
Subtract 528 from 536 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
66 can be fit into 80 1 times, resulting in a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 2578.1
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
66 goes into 140 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2578.12
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 66 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 2578.121
If we take 66 away from 80, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
When dividing 140 by 66, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2578.1212
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
The number 66 fits into 80 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 2578.12121
If we subtract 66 from 80, we 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.

Moving on to step 12:
140 divided by 66 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2578.121212
Deduct 132 from 140 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
66 can be fit into 80 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 2578.1212121
If we take 66 away from 80, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
140 divided by 66 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2578.12121212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 2578.12121212 with a remainder of 8e-09.
