We're dividing 79838472 by 991 
Let's see how many times 991 fits into 79838472.

On to step 1:
If we divide 7 by 991, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 991

On to step 2:
991 can be fit into 79 0 times, resulting in a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 991

Advancing to step 3:
The number 991 fits into 798 0 times, leaving a remainder of 798.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 798, we get 798.
Fetch the next digit (3) from the dividend, attach it to 798 and continue: 7983 / 991

On to step 4:
The number 991 fits into 7983 8 times, leaving a remainder of 55.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 7928 from 7983, we get 55.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 991

Moving on to step 5:
The number 991 fits into 558 0 times, leaving a remainder of 558.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we take 0 away from 558, we end up with 558.
Take the next digit (4) from the dividend and append it to 558, then repeat: 5584 / 991

Let's proceed to step 6:
991 can be fit into 5584 5 times, resulting in a remainder of 629.
Use 5 as the next digit of our solution. 
Result so far: 805.0
The remainder is 629 after subtracting 4955 from 5584.
Bring next digit (7) of the dividend behind the 629 and repeat the process: 6297 / 991

Advancing to step 7:
6297 divided by 991 is 6 with a remainder of 351.
The number 6 becomes the next digit in our result. 
Result so far: 8056.0
If we take 5946 away from 6297, we end up with 351.
Grab the next digit (2) from the dividend, add it to 351, then carry on: 3512 / 991

Let's proceed to step 8:
If we divide 3512 by 991, we get 3 and a remainder of 539.
Record the quotient 3 as the next digit in the result. 
Result so far: 80563.0
Deduct 2973 from 3512 and we're left with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Going ahead to step 9:
5390 divided by 991 is 5 with a remainder of 435.
Write down 5 as next digit of the result. 
Result so far: 80563.5
Subtract 4955 from 5390 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Moving on to step 10:
If we divide 4350 by 991, we get 4 and a remainder of 386.
Put 4 as the next digit of the answer. 
Result so far: 80563.54
If we subtract 3964 from 4350, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 11:
991 goes into 3860 3 times with a remainder of 887.
Use 3 as the next digit of our solution. 
Result so far: 80563.543
If we take 2973 away from 3860, we end up with 887.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8870, and continue the process.

Moving on to step 12:
991 can be fit into 8870 8 times, resulting in a remainder of 942.
The number 8 becomes the next digit in our result. 
Result so far: 80563.5438
The remainder is 942 after subtracting 7928 from 8870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9420, and continue the process.

On to step 13:
991 can be fit into 9420 9 times, resulting in a remainder of 501.
Use 9 as the next digit of our solution. 
Result so far: 80563.54389
Subtracting 8919 from 9420 leaves us with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Step 14:
991 can be fit into 5010 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 80563.543895
The remainder is 55 after subtracting 4955 from 5010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 15:
991 can be fit into 550 0 times, resulting in a remainder of 550.
The next digit of our result is 0. 
Result so far: 80563.543895
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 16:
991 can be fit into 5500 5 times, resulting in a remainder of 545.
Write down 5 as next digit of the result. 
Result so far: 80563.54389505
If we subtract 4955 from 5500, we get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

The final outcome is 80563.54389505, with a leftover of 5.45e-07.
