91722690 ÷ 791 
Let's see how many times 791 fits into 91722690.

Going ahead to step 1:
If we divide 9 by 791, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 791

On to step 2:
791 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 791

Let's proceed to step 3:
If we divide 917 by 791, we get 1 and a remainder of 126.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 791 from 917 and we're left with 126.
Take the next digit (2) from the dividend and append it to 126, then repeat: 1262 / 791

On to step 4:
When dividing 1262 by 791, we get 1 with a remainder of 471.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 471 after subtracting 791 from 1262.
Include the next digit (2) from the dividend after 471, then repeat: 4712 / 791

Going ahead to step 5:
If we divide 4712 by 791, we get 5 and a remainder of 757.
Use 5 as the next digit of our solution. 
Result so far: 115.0
If we subtract 3955 from 4712, we get 757.
Fetch the next digit (6) from the dividend, attach it to 757 and continue: 7576 / 791

Going ahead to step 6:
7576 divided by 791 is 9 with a remainder of 457.
Put 9 as the next digit of the answer. 
Result so far: 1159.0
Deduct 7119 from 7576 and we're left with 457.
Fetch the next digit (9) from the dividend, attach it to 457 and continue: 4579 / 791

Step 7:
When dividing 4579 by 791, we get 5 with a remainder of 624.
The next digit of our result is 5. 
Result so far: 11595.0
Subtracting 3955 from 4579 leaves us with 624.
Take the next digit (0) from the dividend and append it to 624, then repeat: 6240 / 791

Let's proceed to step 8:
If we divide 6240 by 791, we get 7 and a remainder of 703.
Put 7 as the next digit of the answer. 
Result so far: 115957.0
Subtracting 5537 from 6240 leaves us with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Advancing to step 9:
The number 791 fits into 7030 8 times, leaving a remainder of 702.
The number 8 becomes the next digit in our result. 
Result so far: 115957.8
Subtract 6328 from 7030 to get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Step 10:
The number 791 fits into 7020 8 times, leaving a remainder of 692.
Use 8 as the next digit of our solution. 
Result so far: 115957.88
If we take 6328 away from 7020, we end up with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Our division results in 115957.88 with a remaining 0.692.
