We look at the division of 91971135 by 949 
The aim is to understand the frequency of 949 in 91971135.

On to step 1:
949 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 949

Going ahead to step 2:
949 goes into 91 0 times with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Append the next digit (9) from the dividend to 91 and continue with: 919 / 949

Advancing to step 3:
949 goes into 919 0 times with a remainder of 919.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 919 after subtracting 0 from 919.
Take the next digit (7) from the dividend and append it to 919, then repeat: 9197 / 949

Going ahead to step 4:
949 can be fit into 9197 9 times, resulting in a remainder of 656.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 8541 from 9197, we get 656.
Take the next digit (1) from the dividend and append it to 656, then repeat: 6561 / 949

Moving on to step 5:
If we divide 6561 by 949, we get 6 and a remainder of 867.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we take 5694 away from 6561, we end up with 867.
Append the next digit (1) from the dividend to 867 and continue with: 8671 / 949

Going ahead to step 6:
949 goes into 8671 9 times with a remainder of 130.
Record the quotient 9 as the next digit in the result. 
Result so far: 969.0
If we take 8541 away from 8671, we end up with 130.
Include the next digit (3) from the dividend after 130, then repeat: 1303 / 949

Going ahead to step 7:
949 goes into 1303 1 times with a remainder of 354.
The number 1 becomes the next digit in our result. 
Result so far: 9691.0
Subtracting 949 from 1303 leaves us with 354.
Take the next digit (5) from the dividend and append it to 354, then repeat: 3545 / 949

Step 8:
When dividing 3545 by 949, we get 3 with a remainder of 698.
The number 3 becomes the next digit in our result. 
Result so far: 96913.0
If we take 2847 away from 3545, we end up with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Going ahead to step 9:
The number 949 fits into 6980 7 times, leaving a remainder of 337.
Write down 7 as next digit of the result. 
Result so far: 96913.7
The remainder is 337 after subtracting 6643 from 6980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Going ahead to step 10:
3370 divided by 949 is 3 with a remainder of 523.
Put 3 as the next digit of the answer. 
Result so far: 96913.73
Deduct 2847 from 3370 and we're left with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Step 11:
When dividing 5230 by 949, we get 5 with a remainder of 485.
Record the quotient 5 as the next digit in the result. 
Result so far: 96913.735
If we subtract 4745 from 5230, we get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 12:
If we divide 4850 by 949, we get 5 and a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 96913.7355
Subtract 4745 from 4850 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 96913.7355 with a remainder of 0.00105.
