We look at the division of 786456 by 57 
We want to divide 786456 by 57.

Let's proceed to step 1:
The number 57 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 57

Going ahead to step 2:
57 goes into 78 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 57 from 78 and we're left with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 57

Moving on to step 3:
When dividing 216 by 57, we get 3 with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 171 from 216, we get 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 57

On to step 4:
When dividing 454 by 57, we get 7 with a remainder of 55.
The next digit of our result is 7. 
Result so far: 137.0
Deduct 399 from 454 and we're left with 55.
Include the next digit (5) from the dividend after 55, then repeat: 555 / 57

Going ahead to step 5:
555 divided by 57 is 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 1379.0
Deduct 513 from 555 and we're left with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 57

Let's proceed to step 6:
The number 57 fits into 426 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 13797.0
Deduct 399 from 426 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
When dividing 270 by 57, we get 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 13797.4
If we take 228 away from 270, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
420 divided by 57 is 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 13797.47
If we take 399 away from 420, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
57 can be fit into 210 3 times, resulting in a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 13797.473
The remainder is 39 after subtracting 171 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 10:
57 can be fit into 390 6 times, resulting in a remainder of 48.
The next digit of our result is 6. 
Result so far: 13797.4736
If we subtract 342 from 390, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
When dividing 480 by 57, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 13797.47368
Subtracting 456 from 480 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
57 can be fit into 240 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 13797.473684
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
The number 57 fits into 120 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 13797.4736842
Subtract 114 from 120 to 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 14:
60 divided by 57 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 13797.47368421
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 13797.47368421 and a remainder of 3e-09.
