We divide 15213958 by 799
Our goal is to divide 15213958 by 799.

Going ahead to step 1:
1 divided by 799 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 799

Going ahead to step 2:
When dividing 15 by 799, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 799

Let's proceed to step 3:
799 goes into 152 0 times with a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 152 after subtracting 0 from 152.
Append the next digit (1) from the dividend to 152 and continue with: 1521 / 799

On to step 4:
When dividing 1521 by 799, we get 1 with a remainder of 722.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 799 from 1521, we get 722.
Fetch the next digit (3) from the dividend, attach it to 722 and continue: 7223 / 799

Advancing to step 5:
If we divide 7223 by 799, we get 9 and a remainder of 32.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 7191 from 7223 to get 32.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 799

On to step 6:
329 divided by 799 is 0 with a remainder of 329.
Write down 0 as next digit of the result. 
Result so far: 190.0
Subtracting 0 from 329 leaves us with 329.
Fetch the next digit (5) from the dividend, attach it to 329 and continue: 3295 / 799

Step 7:
3295 divided by 799 is 4 with a remainder of 99.
Record the quotient 4 as the next digit in the result. 
Result so far: 1904.0
Deduct 3196 from 3295 and we're left with 99.
Bring next digit (8) of the dividend behind the 99 and repeat the process: 998 / 799

Moving on to step 8:
799 can be fit into 998 1 times, resulting in a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 19041.0
The remainder is 199 after subtracting 799 from 998.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 9:
799 can be fit into 1990 2 times, resulting in a remainder of 392.
The next digit of our result is 2. 
Result so far: 19041.2
Deduct 1598 from 1990 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 10:
When dividing 3920 by 799, we get 4 with a remainder of 724.
The number 4 becomes the next digit in our result. 
Result so far: 19041.24
Deduct 3196 from 3920 and we're left with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Advancing to step 11:
The number 799 fits into 7240 9 times, leaving a remainder of 49.
The next digit of our result is 9. 
Result so far: 19041.249
Subtracting 7191 from 7240 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
799 can be fit into 490 0 times, resulting in a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 19041.249
Subtracting 0 from 490 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 13:
799 goes into 4900 6 times with a remainder of 106.
The number 6 becomes the next digit in our result. 
Result so far: 19041.24906
Subtracting 4794 from 4900 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 14:
The number 799 fits into 1060 1 times, leaving a remainder of 261.
Write down 1 as next digit of the result. 
Result so far: 19041.249061
Subtract 799 from 1060 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 15:
The number 799 fits into 2610 3 times, leaving a remainder of 213.
Use 3 as the next digit of our solution. 
Result so far: 19041.2490613
If we subtract 2397 from 2610, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 16:
2130 divided by 799 is 2 with a remainder of 532.
The next digit of our result is 2. 
Result so far: 19041.24906132
Subtracting 1598 from 2130 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

The final outcome is 19041.24906132, with a leftover of 5.32e-07.
