We're dividing 6219611 by 91 
The aim is to understand the frequency of 91 in 6219611.

Step 1:
91 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 91

Advancing to step 2:
When dividing 62 by 91, we get 0 with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 91

Advancing to step 3:
91 can be fit into 621 6 times, resulting in a remainder of 75.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 546 from 621 leaves us with 75.
Include the next digit (9) from the dividend after 75, then repeat: 759 / 91

Moving on to step 4:
The number 91 fits into 759 8 times, leaving a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
If we subtract 728 from 759, we get 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 91

Moving on to step 5:
If we divide 316 by 91, we get 3 and a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 683.0
If we subtract 273 from 316, we get 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 91

On to step 6:
91 goes into 431 4 times with a remainder of 67.
Put 4 as the next digit of the answer. 
Result so far: 6834.0
Subtracting 364 from 431 leaves us with 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 91

Going ahead to step 7:
The number 91 fits into 671 7 times, leaving a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 68347.0
If we subtract 637 from 671, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
340 divided by 91 is 3 with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 68347.3
If we subtract 273 from 340, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
When dividing 670 by 91, we get 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 68347.37
Subtract 637 from 670 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
When dividing 330 by 91, we get 3 with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 68347.373
Subtracting 273 from 330 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 11:
91 can be fit into 570 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 68347.3736
Subtracting 546 from 570 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
If we divide 240 by 91, we get 2 and a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 68347.37362
The remainder is 58 after subtracting 182 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 13:
The number 91 fits into 580 6 times, leaving a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 68347.373626
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
91 can be fit into 340 3 times, resulting in a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 68347.3736263
If we take 273 away from 340, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 15:
When dividing 670 by 91, we get 7 with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 68347.37362637
Subtracting 637 from 670 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Our division results in 68347.37362637 with a remaining 3.3e-08.
