We divide 99119091 by 371
The aim is to understand the frequency of 371 in 99119091.

Going ahead to step 1:
9 divided by 371 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 371

On to step 2:
371 goes into 99 0 times 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.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 371

On to step 3:
991 divided by 371 is 2 with a remainder of 249.
The next digit of our result is 2. 
Result so far: 2.0
If we take 742 away from 991, we end up with 249.
Fetch the next digit (1) from the dividend, attach it to 249 and continue: 2491 / 371

On to step 4:
371 goes into 2491 6 times with a remainder of 265.
Use 6 as the next digit of our solution. 
Result so far: 26.0
The remainder is 265 after subtracting 2226 from 2491.
Grab the next digit (9) from the dividend, add it to 265, then carry on: 2659 / 371

Going ahead to step 5:
371 goes into 2659 7 times with a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 267.0
If we subtract 2597 from 2659, we get 62.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 371

Let's proceed to step 6:
371 can be fit into 620 1 times, resulting in a remainder of 249.
Write down 1 as next digit of the result. 
Result so far: 2671.0
Subtract 371 from 620 to get 249.
Include the next digit (9) from the dividend after 249, then repeat: 2499 / 371

Advancing to step 7:
371 can be fit into 2499 6 times, resulting in a remainder of 273.
The number 6 becomes the next digit in our result. 
Result so far: 26716.0
If we subtract 2226 from 2499, we get 273.
Include the next digit (1) from the dividend after 273, then repeat: 2731 / 371

On to step 8:
When dividing 2731 by 371, we get 7 with a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 267167.0
Subtracting 2597 from 2731 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 9:
371 can be fit into 1340 3 times, resulting in a remainder of 227.
The number 3 becomes the next digit in our result. 
Result so far: 267167.3
If we take 1113 away from 1340, we end up with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Moving on to step 10:
371 goes into 2270 6 times with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 267167.36
Subtract 2226 from 2270 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
440 divided by 371 is 1 with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 267167.361
If we take 371 away from 440, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 12:
371 goes into 690 1 times with a remainder of 319.
Use 1 as the next digit of our solution. 
Result so far: 267167.3611
If we subtract 371 from 690, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

The final result is 267167.3611 with a remainder of 0.00319.
