99220750 divided by 397 
We want to figure out the number of times 99220750 can be divided by 397.

Going ahead to step 1:
9 divided by 397 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 397

Let's proceed to step 2:
99 divided by 397 is 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Bring next digit (2) of the dividend behind the 99 and repeat the process: 992 / 397

Going ahead to step 3:
397 can be fit into 992 2 times, resulting in a remainder of 198.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 198 after subtracting 794 from 992.
Take the next digit (2) from the dividend and append it to 198, then repeat: 1982 / 397

On to step 4:
1982 divided by 397 is 4 with a remainder of 394.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 1588 from 1982, we get 394.
Grab the next digit (0) from the dividend, add it to 394, then carry on: 3940 / 397

On to step 5:
The number 397 fits into 3940 9 times, leaving a remainder of 367.
The next digit of our result is 9. 
Result so far: 249.0
Subtracting 3573 from 3940 leaves us with 367.
Fetch the next digit (7) from the dividend, attach it to 367 and continue: 3677 / 397

Going ahead to step 6:
The number 397 fits into 3677 9 times, leaving a remainder of 104.
The number 9 becomes the next digit in our result. 
Result so far: 2499.0
The remainder is 104 after subtracting 3573 from 3677.
Include the next digit (5) from the dividend after 104, then repeat: 1045 / 397

On to step 7:
397 goes into 1045 2 times with a remainder of 251.
Write down 2 as next digit of the result. 
Result so far: 24992.0
The remainder is 251 after subtracting 794 from 1045.
Include the next digit (0) from the dividend after 251, then repeat: 2510 / 397

Let's proceed to step 8:
397 goes into 2510 6 times with a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 249926.0
If we subtract 2382 from 2510, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 9:
When dividing 1280 by 397, we get 3 with a remainder of 89.
Write down 3 as next digit of the result. 
Result so far: 249926.3
Deduct 1191 from 1280 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 10:
890 divided by 397 is 2 with a remainder of 96.
The next digit of our result is 2. 
Result so far: 249926.32
If we take 794 away from 890, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 11:
397 can be fit into 960 2 times, resulting in a remainder of 166.
Write down 2 as next digit of the result. 
Result so far: 249926.322
The remainder is 166 after subtracting 794 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final result is 249926.322 with a remainder of 0.0166.
