Let's divide 918201 by 91
The aim is to understand the frequency of 91 in 918201.

Moving on to step 1:
91 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 91

Step 2:
The number 91 fits into 91 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 91 from 91 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 91

Let's proceed to step 3:
8 divided by 91 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 91

Advancing to step 4:
When dividing 82 by 91, we get 0 with a remainder of 82.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 82 and we're left with 82.
Fetch the next digit (0) from the dividend, attach it to 82 and continue: 820 / 91

Moving on to step 5:
91 can be fit into 820 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1009.0
Deduct 819 from 820 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 91

Moving on to step 6:
91 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 10090.0
If we subtract 0 from 11, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
110 divided by 91 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 10090.1
Subtracting 91 from 110 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
If we divide 190 by 91, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 10090.12
The remainder is 8 after subtracting 182 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
91 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 10090.12
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
91 can be fit into 800 8 times, resulting in a remainder of 72.
The next digit of our result is 8. 
Result so far: 10090.1208
The remainder is 72 after subtracting 728 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 11:
91 can be fit into 720 7 times, resulting in a remainder of 83.
The next digit of our result is 7. 
Result so far: 10090.12087
If we subtract 637 from 720, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 12:
91 goes into 830 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 10090.120879
If we subtract 819 from 830, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
91 goes into 110 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 10090.1208791
If we subtract 91 from 110, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 14:
When dividing 190 by 91, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 10090.12087912
Subtracting 182 from 190 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 10090.12087912, with a leftover of 8e-09.
