99231901 divided by 397 
We want to figure out the number of times 99231901 can be divided by 397.

Moving on 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
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 397

Step 2:
When dividing 99 by 397, we get 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (2) from the dividend after 99, then repeat: 992 / 397

Advancing to step 3:
The number 397 fits into 992 2 times, leaving a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 794 from 992 to get 198.
Fetch the next digit (3) from the dividend, attach it to 198 and continue: 1983 / 397

Going ahead to step 4:
397 goes into 1983 4 times with a remainder of 395.
The next digit of our result is 4. 
Result so far: 24.0
If we take 1588 away from 1983, we end up with 395.
Fetch the next digit (1) from the dividend, attach it to 395 and continue: 3951 / 397

Advancing to step 5:
397 goes into 3951 9 times with a remainder of 378.
Write down 9 as next digit of the result. 
Result so far: 249.0
Subtract 3573 from 3951 to get 378.
Take the next digit (9) from the dividend and append it to 378, then repeat: 3789 / 397

On to step 6:
397 can be fit into 3789 9 times, resulting in a remainder of 216.
Write down 9 as next digit of the result. 
Result so far: 2499.0
Deduct 3573 from 3789 and we're left with 216.
Append the next digit (0) from the dividend to 216 and continue with: 2160 / 397

On to step 7:
The number 397 fits into 2160 5 times, leaving a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 24995.0
Subtracting 1985 from 2160 leaves us with 175.
Fetch the next digit (1) from the dividend, attach it to 175 and continue: 1751 / 397

On to step 8:
If we divide 1751 by 397, we get 4 and a remainder of 163.
The next digit of our result is 4. 
Result so far: 249954.0
If we subtract 1588 from 1751, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 9:
When dividing 1630 by 397, we get 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 249954.4
If we subtract 1588 from 1630, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
When dividing 420 by 397, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 249954.41
If we subtract 397 from 420, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
The number 397 fits into 230 0 times, leaving a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 249954.41
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 12:
If we divide 2300 by 397, we get 5 and a remainder of 315.
Write down 5 as next digit of the result. 
Result so far: 249954.4105
Deduct 1985 from 2300 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 13:
397 goes into 3150 7 times with a remainder of 371.
Write down 7 as next digit of the result. 
Result so far: 249954.41057
If we subtract 2779 from 3150, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 14:
397 can be fit into 3710 9 times, resulting in a remainder of 137.
Record the quotient 9 as the next digit in the result. 
Result so far: 249954.410579
If we take 3573 away from 3710, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Let's proceed to step 15:
397 can be fit into 1370 3 times, resulting in a remainder of 179.
Write down 3 as next digit of the result. 
Result so far: 249954.4105793
If we take 1191 away from 1370, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 16:
397 goes into 1790 4 times with a remainder of 202.
Use 4 as the next digit of our solution. 
Result so far: 249954.41057934
Subtract 1588 from 1790 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The final result is 249954.41057934 with a remainder of 2.02e-07.
