Let's divide 807041 by 91
The aim is to understand the frequency of 91 in 807041.

On to step 1:
The number 91 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 91

On to step 2:
If we divide 80 by 91, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 91

On to step 3:
If we divide 807 by 91, we get 8 and a remainder of 79.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 728 away from 807, we end up with 79.
Fetch the next digit (0) from the dividend, attach it to 79 and continue: 790 / 91

Going ahead to step 4:
If we divide 790 by 91, we get 8 and a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
If we subtract 728 from 790, we get 62.
Fetch the next digit (4) from the dividend, attach it to 62 and continue: 624 / 91

Moving on to step 5:
When dividing 624 by 91, we get 6 with a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 886.0
If we subtract 546 from 624, we get 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 91

Advancing to step 6:
When dividing 781 by 91, we get 8 with a remainder of 53.
The next digit of our result is 8. 
Result so far: 8868.0
If we take 728 away from 781, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
91 goes into 530 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 8868.5
If we take 455 away from 530, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 8:
The number 91 fits into 750 8 times, leaving a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 8868.58
If we subtract 728 from 750, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
The number 91 fits into 220 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 8868.582
If we take 182 away from 220, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
The number 91 fits into 380 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 8868.5824
Deduct 364 from 380 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
When dividing 160 by 91, we get 1 with a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 8868.58241
The remainder is 69 after subtracting 91 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 12:
When dividing 690 by 91, we get 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 8868.582417
The remainder is 53 after subtracting 637 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 13:
If we divide 530 by 91, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 8868.5824175
The remainder is 75 after subtracting 455 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
750 divided by 91 is 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 8868.58241758
Subtract 728 from 750 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 8868.58241758 with a balance of 2.2e-08.
