99831361 ÷ 397 
The aim is to understand the frequency of 397 in 99831361.

Going ahead to step 1:
If we divide 9 by 397, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 397

Let's proceed to step 2:
397 can be fit into 99 0 times, resulting in a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Fetch the next digit (8) from the dividend, attach it to 99 and continue: 998 / 397

Step 3:
397 goes into 998 2 times with a remainder of 204.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 794 from 998 to get 204.
Fetch the next digit (3) from the dividend, attach it to 204 and continue: 2043 / 397

Advancing to step 4:
When dividing 2043 by 397, we get 5 with a remainder of 58.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 1985 from 2043, we get 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 397

Step 5:
When dividing 581 by 397, we get 1 with a remainder of 184.
Put 1 as the next digit of the answer. 
Result so far: 251.0
Deduct 397 from 581 and we're left with 184.
Append the next digit (3) from the dividend to 184 and continue with: 1843 / 397

Advancing to step 6:
If we divide 1843 by 397, we get 4 and a remainder of 255.
Write down 4 as next digit of the result. 
Result so far: 2514.0
The remainder is 255 after subtracting 1588 from 1843.
Fetch the next digit (6) from the dividend, attach it to 255 and continue: 2556 / 397

Step 7:
397 can be fit into 2556 6 times, resulting in a remainder of 174.
Put 6 as the next digit of the answer. 
Result so far: 25146.0
Deduct 2382 from 2556 and we're left with 174.
Grab the next digit (1) from the dividend, add it to 174, then carry on: 1741 / 397

Going ahead to step 8:
The number 397 fits into 1741 4 times, leaving a remainder of 153.
Record the quotient 4 as the next digit in the result. 
Result so far: 251464.0
If we subtract 1588 from 1741, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 9:
If we divide 1530 by 397, we get 3 and a remainder of 339.
Put 3 as the next digit of the answer. 
Result so far: 251464.3
If we take 1191 away from 1530, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

On to step 10:
The number 397 fits into 3390 8 times, leaving a remainder of 214.
Record the quotient 8 as the next digit in the result. 
Result so far: 251464.38
Deduct 3176 from 3390 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 11:
If we divide 2140 by 397, we get 5 and a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 251464.385
If we take 1985 away from 2140, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 12:
When dividing 1550 by 397, we get 3 with a remainder of 359.
Write down 3 as next digit of the result. 
Result so far: 251464.3853
The remainder is 359 after subtracting 1191 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Step 13:
If we divide 3590 by 397, we get 9 and a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 251464.38539
Deduct 3573 from 3590 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 14:
397 can be fit into 170 0 times, resulting in a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 251464.38539
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 15:
397 goes into 1700 4 times with a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 251464.3853904
Subtracting 1588 from 1700 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 16:
1120 divided by 397 is 2 with a remainder of 326.
The number 2 becomes the next digit in our result. 
Result so far: 251464.38539042
Deduct 794 from 1120 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Our division results in 251464.38539042 with a remaining 3.26e-07.
