We look at the division of 56578021 by 171 
Our goal is to divide 56578021 by 171.

Let's proceed to step 1:
171 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 171

Advancing to step 2:
171 goes into 56 0 times with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Grab the next digit (5) from the dividend, add it to 56, then carry on: 565 / 171

Moving on to step 3:
171 goes into 565 3 times with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 513 from 565 leaves us with 52.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 171

Step 4:
If we divide 527 by 171, we get 3 and a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we subtract 513 from 527, we get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 171

Let's proceed to step 5:
171 goes into 148 0 times with a remainder of 148.
The number 0 becomes the next digit in our result. 
Result so far: 330.0
If we subtract 0 from 148, we get 148.
Include the next digit (0) from the dividend after 148, then repeat: 1480 / 171

Moving on to step 6:
171 goes into 1480 8 times with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 3308.0
Subtracting 1368 from 1480 leaves us with 112.
Take the next digit (2) from the dividend and append it to 112, then repeat: 1122 / 171

Let's proceed to step 7:
The number 171 fits into 1122 6 times, leaving a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 33086.0
If we subtract 1026 from 1122, we get 96.
Take the next digit (1) from the dividend and append it to 96, then repeat: 961 / 171

Let's proceed to step 8:
When dividing 961 by 171, we get 5 with a remainder of 106.
Put 5 as the next digit of the answer. 
Result so far: 330865.0
Deduct 855 from 961 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 9:
The number 171 fits into 1060 6 times, leaving a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 330865.6
Subtracting 1026 from 1060 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
340 divided by 171 is 1 with a remainder of 169.
The next digit of our result is 1. 
Result so far: 330865.61
Subtract 171 from 340 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 11:
When dividing 1690 by 171, we get 9 with a remainder of 151.
Record the quotient 9 as the next digit in the result. 
Result so far: 330865.619
If we subtract 1539 from 1690, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Moving on to step 12:
171 can be fit into 1510 8 times, resulting in a remainder of 142.
Record the quotient 8 as the next digit in the result. 
Result so far: 330865.6198
The remainder is 142 after subtracting 1368 from 1510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 13:
The number 171 fits into 1420 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 330865.61988
The remainder is 52 after subtracting 1368 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 330865.61988 and a remainder of 5.2e-05.
