We look at the division of 645388 by 57 
Our goal is to divide 645388 by 57.

Let's proceed to step 1:
When dividing 6 by 57, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 57

Advancing to step 2:
If we divide 64 by 57, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
If we take 57 away from 64, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 57

Advancing to step 3:
If we divide 75 by 57, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 57 away from 75, we end up with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 57

On to step 4:
The number 57 fits into 183 3 times, leaving a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
If we take 171 away from 183, we end up with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 57

Step 5:
The number 57 fits into 128 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 1132.0
If we subtract 114 from 128, we get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 57

On to step 6:
If we divide 148 by 57, we get 2 and a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 11322.0
If we subtract 114 from 148, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
When dividing 340 by 57, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 11322.5
If we take 285 away from 340, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 8:
550 divided by 57 is 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 11322.59
Subtract 513 from 550 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
The number 57 fits into 370 6 times, leaving a remainder of 28.
The next digit of our result is 6. 
Result so far: 11322.596
Subtracting 342 from 370 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
57 can be fit into 280 4 times, resulting in a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 11322.5964
Subtracting 228 from 280 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
If we divide 520 by 57, we get 9 and a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 11322.59649
Subtracting 513 from 520 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
57 goes into 70 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 11322.596491
If we take 57 away from 70, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 13:
If we divide 130 by 57, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 11322.5964912
Subtract 114 from 130 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
160 divided by 57 is 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 11322.59649122
If we subtract 114 from 160, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 11322.59649122 with a remainder of 4.6e-08.
