Let's divide 198045 by 91
The aim is to understand the frequency of 91 in 198045.

Going ahead to step 1:
If we divide 1 by 91, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 91

Step 2:
91 goes into 19 0 times with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 91

Let's proceed to step 3:
The number 91 fits into 198 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 182 from 198 leaves us with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 91

Going ahead to step 4:
When dividing 160 by 91, we get 1 with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 91 from 160 leaves us with 69.
Include the next digit (4) from the dividend after 69, then repeat: 694 / 91

Moving on to step 5:
If we divide 694 by 91, we get 7 and a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 217.0
The remainder is 57 after subtracting 637 from 694.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 91

Moving on to step 6:
If we divide 575 by 91, we get 6 and a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 2176.0
Deduct 546 from 575 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
91 goes into 290 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 2176.3
Subtract 273 from 290 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
91 can be fit into 170 1 times, resulting in a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 2176.31
If we take 91 away from 170, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 9:
91 goes into 790 8 times with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 2176.318
Deduct 728 from 790 and we're left 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.

Moving on to step 10:
91 goes into 620 6 times with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 2176.3186
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 11:
If we divide 740 by 91, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 2176.31868
Deduct 728 from 740 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
When dividing 120 by 91, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 2176.318681
If we take 91 away from 120, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
The number 91 fits into 290 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 2176.3186813
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
91 can be fit into 170 1 times, resulting in a remainder of 79.
The next digit of our result is 1. 
Result so far: 2176.31868131
Subtract 91 from 170 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The quotient of the division is 2176.31868131, and the remainder is 7.9e-08.
