We look at the division of 15920466 by 799 
We're looking to find how many times 799 goes into 15920466.

Step 1:
The number 799 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 799

Advancing to step 2:
If we divide 15 by 799, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 799

Advancing to step 3:
If we divide 159 by 799, we get 0 and a remainder of 159.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 159 and we're left with 159.
Include the next digit (2) from the dividend after 159, then repeat: 1592 / 799

Moving on to step 4:
799 can be fit into 1592 1 times, resulting in a remainder of 793.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 799 from 1592 leaves us with 793.
Take the next digit (0) from the dividend and append it to 793, then repeat: 7930 / 799

Going ahead to step 5:
When dividing 7930 by 799, we get 9 with a remainder of 739.
The next digit of our result is 9. 
Result so far: 19.0
If we take 7191 away from 7930, we end up with 739.
Fetch the next digit (4) from the dividend, attach it to 739 and continue: 7394 / 799

Step 6:
When dividing 7394 by 799, we get 9 with a remainder of 203.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
The remainder is 203 after subtracting 7191 from 7394.
Append the next digit (6) from the dividend to 203 and continue with: 2036 / 799

On to step 7:
When dividing 2036 by 799, we get 2 with a remainder of 438.
Record the quotient 2 as the next digit in the result. 
Result so far: 1992.0
Deduct 1598 from 2036 and we're left with 438.
Fetch the next digit (6) from the dividend, attach it to 438 and continue: 4386 / 799

On to step 8:
4386 divided by 799 is 5 with a remainder of 391.
The number 5 becomes the next digit in our result. 
Result so far: 19925.0
Subtract 3995 from 4386 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Step 9:
3910 divided by 799 is 4 with a remainder of 714.
Use 4 as the next digit of our solution. 
Result so far: 19925.4
The remainder is 714 after subtracting 3196 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Let's proceed to step 10:
If we divide 7140 by 799, we get 8 and a remainder of 748.
Put 8 as the next digit of the answer. 
Result so far: 19925.48
If we take 6392 away from 7140, we end up with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Step 11:
When dividing 7480 by 799, we get 9 with a remainder of 289.
The next digit of our result is 9. 
Result so far: 19925.489
The remainder is 289 after subtracting 7191 from 7480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 12:
799 can be fit into 2890 3 times, resulting in a remainder of 493.
The number 3 becomes the next digit in our result. 
Result so far: 19925.4893
If we subtract 2397 from 2890, we get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Going ahead to step 13:
If we divide 4930 by 799, we get 6 and a remainder of 136.
The next digit of our result is 6. 
Result so far: 19925.48936
Deduct 4794 from 4930 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 14:
1360 divided by 799 is 1 with a remainder of 561.
Record the quotient 1 as the next digit in the result. 
Result so far: 19925.489361
If we subtract 799 from 1360, we get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Step 15:
The number 799 fits into 5610 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 19925.4893617
Subtracting 5593 from 5610 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 16:
170 divided by 799 is 0 with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 19925.4893617
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The quotient of the division is 19925.4893617, and the remainder is 1.7e-07.
