78871279 divided by 57 
We want to divide 78871279 by 57.

On to step 1:
If we divide 7 by 57, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 57

Step 2:
If we divide 78 by 57, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 57 from 78 and we're left with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 57

On to step 3:
The number 57 fits into 218 3 times, leaving a remainder of 47.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 171 from 218, we get 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 57

On to step 4:
477 divided by 57 is 8 with a remainder of 21.
The next digit of our result is 8. 
Result so far: 138.0
The remainder is 21 after subtracting 456 from 477.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 57

On to step 5:
If we divide 211 by 57, we get 3 and a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 1383.0
Subtracting 171 from 211 leaves us with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 57

Going ahead to step 6:
If we divide 402 by 57, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 13837.0
If we subtract 399 from 402, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 57

Going ahead to step 7:
The number 57 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 138370.0
If we take 0 away from 37, we end up with 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 57

Moving on to step 8:
57 can be fit into 379 6 times, resulting in a remainder of 37.
The next digit of our result is 6. 
Result so far: 1383706.0
If we take 342 away from 379, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
370 divided by 57 is 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 1383706.6
Subtract 342 from 370 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
If we divide 280 by 57, we get 4 and a remainder of 52.
The next digit of our result is 4. 
Result so far: 1383706.64
If we subtract 228 from 280, we get 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:
520 divided by 57 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 1383706.649
Deduct 513 from 520 and we're left 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.

Let's proceed to step 12:
If we divide 70 by 57, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1383706.6491
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.

Going ahead to step 13:
When dividing 130 by 57, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 1383706.64912
If we take 114 away from 130, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
When dividing 160 by 57, we get 2 with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 1383706.649122
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 quotient of the division is 1383706.649122, and the remainder is 4.6e-06.
