88097221 ÷ 831 
We want to figure out the number of times 88097221 can be divided by 831.

Let's proceed to step 1:
The number 831 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 831

On to step 2:
The number 831 fits into 88 0 times, leaving a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Fetch the next digit (0) from the dividend, attach it to 88 and continue: 880 / 831

Step 3:
When dividing 880 by 831, we get 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 831 from 880 and we're left with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 831

Advancing to step 4:
499 divided by 831 is 0 with a remainder of 499.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 499, we get 499.
Grab the next digit (7) from the dividend, add it to 499, then carry on: 4997 / 831

On to step 5:
The number 831 fits into 4997 6 times, leaving a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
Subtracting 4986 from 4997 leaves us with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 831

Advancing to step 6:
If we divide 112 by 831, we get 0 and a remainder of 112.
The next digit of our result is 0. 
Result so far: 1060.0
Subtract 0 from 112 to get 112.
Include the next digit (2) from the dividend after 112, then repeat: 1122 / 831

Moving on to step 7:
If we divide 1122 by 831, we get 1 and a remainder of 291.
Put 1 as the next digit of the answer. 
Result so far: 10601.0
If we subtract 831 from 1122, we get 291.
Take the next digit (1) from the dividend and append it to 291, then repeat: 2911 / 831

On to step 8:
831 can be fit into 2911 3 times, resulting in a remainder of 418.
The number 3 becomes the next digit in our result. 
Result so far: 106013.0
If we take 2493 away from 2911, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 9:
The number 831 fits into 4180 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 106013.5
If we subtract 4155 from 4180, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
831 goes into 250 0 times with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 106013.5
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 11:
The number 831 fits into 2500 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 106013.503
If we take 2493 away from 2500, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
When dividing 70 by 831, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 106013.503
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
The number 831 fits into 700 0 times, leaving a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 106013.503
If we take 0 away from 700, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Our division results in 106013.503 with a remaining 0.0007.
