We look at the division of 57242839 by 799 
Let's see how many times 799 fits into 57242839.

Advancing to step 1:
5 divided by 799 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 799

Advancing to step 2:
The number 799 fits into 57 0 times, leaving a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Grab the next digit (2) from the dividend, add it to 57, then carry on: 572 / 799

Step 3:
572 divided by 799 is 0 with a remainder of 572.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 572, we get 572.
Append the next digit (4) from the dividend to 572 and continue with: 5724 / 799

Step 4:
If we divide 5724 by 799, we get 7 and a remainder of 131.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 5593 from 5724, we get 131.
Bring next digit (2) of the dividend behind the 131 and repeat the process: 1312 / 799

On to step 5:
1312 divided by 799 is 1 with a remainder of 513.
The next digit of our result is 1. 
Result so far: 71.0
Deduct 799 from 1312 and we're left with 513.
Include the next digit (8) from the dividend after 513, then repeat: 5138 / 799

Going ahead to step 6:
When dividing 5138 by 799, we get 6 with a remainder of 344.
The next digit of our result is 6. 
Result so far: 716.0
Subtract 4794 from 5138 to get 344.
Include the next digit (3) from the dividend after 344, then repeat: 3443 / 799

Going ahead to step 7:
If we divide 3443 by 799, we get 4 and a remainder of 247.
The next digit of our result is 4. 
Result so far: 7164.0
Subtracting 3196 from 3443 leaves us with 247.
Include the next digit (9) from the dividend after 247, then repeat: 2479 / 799

Let's proceed to step 8:
2479 divided by 799 is 3 with a remainder of 82.
The next digit of our result is 3. 
Result so far: 71643.0
Subtracting 2397 from 2479 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
The number 799 fits into 820 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 71643.1
Subtracting 799 from 820 leaves us 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.

On to step 10:
When dividing 210 by 799, we get 0 with a remainder of 210.
The next digit of our result is 0. 
Result so far: 71643.1
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 11:
The number 799 fits into 2100 2 times, leaving a remainder of 502.
The next digit of our result is 2. 
Result so far: 71643.102
Subtract 1598 from 2100 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Let's proceed to step 12:
The number 799 fits into 5020 6 times, leaving a remainder of 226.
Put 6 as the next digit of the answer. 
Result so far: 71643.1026
If we take 4794 away from 5020, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 13:
2260 divided by 799 is 2 with a remainder of 662.
The number 2 becomes the next digit in our result. 
Result so far: 71643.10262
Subtracting 1598 from 2260 leaves us with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Advancing to step 14:
If we divide 6620 by 799, we get 8 and a remainder of 228.
The number 8 becomes the next digit in our result. 
Result so far: 71643.102628
Subtract 6392 from 6620 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 15:
If we divide 2280 by 799, we get 2 and a remainder of 682.
The number 2 becomes the next digit in our result. 
Result so far: 71643.1026282
Subtract 1598 from 2280 to get 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Let's proceed to step 16:
The number 799 fits into 6820 8 times, leaving a remainder of 428.
Use 8 as the next digit of our solution. 
Result so far: 71643.10262828
Deduct 6392 from 6820 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

After the division, we end up with 71643.10262828 and a remainder of 4.28e-07.
