We're dividing 91215373 by 113 
The aim is to understand the frequency of 113 in 91215373.

Going ahead to step 1:
113 can be fit into 9 0 times, resulting in 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.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 113

Advancing to step 2:
If we divide 91 by 113, we get 0 and a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Grab the next digit (2) from the dividend, add it to 91, then carry on: 912 / 113

Step 3:
113 goes into 912 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 904 from 912, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 113

Going ahead to step 4:
If we divide 81 by 113, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we subtract 0 from 81, we get 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 113

Advancing to step 5:
The number 113 fits into 815 7 times, leaving a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 807.0
Deduct 791 from 815 and we're left with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 113

Step 6:
113 can be fit into 243 2 times, resulting in a remainder of 17.
The next digit of our result is 2. 
Result so far: 8072.0
Subtract 226 from 243 to get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 113

On to step 7:
If we divide 177 by 113, we get 1 and a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 80721.0
The remainder is 64 after subtracting 113 from 177.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 113

Let's proceed to step 8:
When dividing 643 by 113, we get 5 with a remainder of 78.
Use 5 as the next digit of our solution. 
Result so far: 807215.0
Subtracting 565 from 643 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
When dividing 780 by 113, we get 6 with a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 807215.6
If we take 678 away from 780, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 10:
When dividing 1020 by 113, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 807215.69
If we subtract 1017 from 1020, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
113 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 807215.69
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
When dividing 300 by 113, we get 2 with a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 807215.6902
The remainder is 74 after subtracting 226 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 13:
When dividing 740 by 113, we get 6 with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 807215.69026
Subtracting 678 from 740 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
If we divide 620 by 113, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 807215.690265
The remainder is 55 after subtracting 565 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 15:
550 divided by 113 is 4 with a remainder of 98.
Record the quotient 4 as the next digit in the result. 
Result so far: 807215.6902654
Subtract 452 from 550 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 16:
113 can be fit into 980 8 times, resulting in a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 807215.69026548
Deduct 904 from 980 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 807215.69026548, with a leftover of 7.6e-08.
