Let's divide 19668789 by 799
We want to divide 19668789 by 799.

On to step 1:
799 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 799

On to step 2:
When dividing 19 by 799, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 799

Advancing to step 3:
When dividing 196 by 799, we get 0 with a remainder of 196.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 196 to get 196.
Append the next digit (6) from the dividend to 196 and continue with: 1966 / 799

Going ahead to step 4:
If we divide 1966 by 799, we get 2 and a remainder of 368.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1598 from 1966 to get 368.
Grab the next digit (8) from the dividend, add it to 368, then carry on: 3688 / 799

Advancing to step 5:
If we divide 3688 by 799, we get 4 and a remainder of 492.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 3196 from 3688, we get 492.
Grab the next digit (7) from the dividend, add it to 492, then carry on: 4927 / 799

Step 6:
799 can be fit into 4927 6 times, resulting in a remainder of 133.
The next digit of our result is 6. 
Result so far: 246.0
Deduct 4794 from 4927 and we're left with 133.
Take the next digit (8) from the dividend and append it to 133, then repeat: 1338 / 799

On to step 7:
1338 divided by 799 is 1 with a remainder of 539.
The number 1 becomes the next digit in our result. 
Result so far: 2461.0
Subtract 799 from 1338 to get 539.
Fetch the next digit (9) from the dividend, attach it to 539 and continue: 5399 / 799

Going ahead to step 8:
When dividing 5399 by 799, we get 6 with a remainder of 605.
The next digit of our result is 6. 
Result so far: 24616.0
If we take 4794 away from 5399, we end up with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Advancing to step 9:
When dividing 6050 by 799, we get 7 with a remainder of 457.
Write down 7 as next digit of the result. 
Result so far: 24616.7
If we subtract 5593 from 6050, we get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Moving on to step 10:
799 goes into 4570 5 times with a remainder of 575.
Record the quotient 5 as the next digit in the result. 
Result so far: 24616.75
Deduct 3995 from 4570 and we're left with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Going ahead to step 11:
When dividing 5750 by 799, we get 7 with a remainder of 157.
The next digit of our result is 7. 
Result so far: 24616.757
Subtracting 5593 from 5750 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 12:
If we divide 1570 by 799, we get 1 and a remainder of 771.
Put 1 as the next digit of the answer. 
Result so far: 24616.7571
The remainder is 771 after subtracting 799 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

Going ahead to step 13:
799 goes into 7710 9 times with a remainder of 519.
Put 9 as the next digit of the answer. 
Result so far: 24616.75719
The remainder is 519 after subtracting 7191 from 7710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Advancing to step 14:
If we divide 5190 by 799, we get 6 and a remainder of 396.
The next digit of our result is 6. 
Result so far: 24616.757196
Deduct 4794 from 5190 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 15:
The number 799 fits into 3960 4 times, leaving a remainder of 764.
The number 4 becomes the next digit in our result. 
Result so far: 24616.7571964
The remainder is 764 after subtracting 3196 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

On to step 16:
7640 divided by 799 is 9 with a remainder of 449.
The next digit of our result is 9. 
Result so far: 24616.75719649
Subtracting 7191 from 7640 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Our division results in 24616.75719649 with a remaining 4.49e-07.
