We look at the division of 78099 by 57 
Our goal is to divide 78099 by 57.

Advancing to step 1:
If we divide 7 by 57, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 57

Moving on to step 2:
57 goes into 78 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 57 away from 78, we end up with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 57

Moving on to step 3:
57 goes into 210 3 times with a remainder of 39.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 39 after subtracting 171 from 210.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 57

On to step 4:
399 divided by 57 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Deduct 399 from 399 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 57

Going ahead to step 5:
57 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 1370.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 6:
57 can be fit into 90 1 times, resulting in a remainder of 33.
The next digit of our result is 1. 
Result so far: 1370.1
Subtracting 57 from 90 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
If we divide 330 by 57, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1370.15
The remainder is 45 after subtracting 285 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
450 divided by 57 is 7 with a remainder of 51.
The next digit of our result is 7. 
Result so far: 1370.157
Subtract 399 from 450 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
The number 57 fits into 510 8 times, leaving a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 1370.1578
The remainder is 54 after subtracting 456 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
57 can be fit into 540 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 1370.15789
Subtract 513 from 540 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 11:
57 goes into 270 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 1370.157894
Subtracting 228 from 270 leaves us 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.

Moving on to step 12:
420 divided by 57 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 1370.1578947
The remainder is 21 after subtracting 399 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
57 can be fit into 210 3 times, resulting in a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 1370.15789473
Deduct 171 from 210 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 1370.15789473, and the remainder is 3.9e-08.
