We divide 426652 by 91
The aim is to understand the frequency of 91 in 426652.

On to step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 91

Moving on to step 2:
91 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 91

Step 3:
91 can be fit into 426 4 times, resulting in a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 62 after subtracting 364 from 426.
Bring next digit (6) of the dividend behind the 62 and repeat the process: 626 / 91

Let's proceed to step 4:
The number 91 fits into 626 6 times, leaving a remainder of 80.
The next digit of our result is 6. 
Result so far: 46.0
Subtract 546 from 626 to get 80.
Grab the next digit (5) from the dividend, add it to 80, then carry on: 805 / 91

Let's proceed to step 5:
91 goes into 805 8 times with a remainder of 77.
The next digit of our result is 8. 
Result so far: 468.0
If we subtract 728 from 805, we get 77.
Bring next digit (2) of the dividend behind the 77 and repeat the process: 772 / 91

Let's proceed to step 6:
When dividing 772 by 91, we get 8 with a remainder of 44.
The next digit of our result is 8. 
Result so far: 4688.0
Subtract 728 from 772 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
91 can be fit into 440 4 times, resulting in a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 4688.4
Subtract 364 from 440 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 8:
91 can be fit into 760 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 4688.48
If we subtract 728 from 760, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
When dividing 320 by 91, we get 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 4688.483
Subtract 273 from 320 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 10:
When dividing 470 by 91, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 4688.4835
If we subtract 455 from 470, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
If we divide 150 by 91, we get 1 and a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 4688.48351
If we subtract 91 from 150, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 12:
When dividing 590 by 91, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 4688.483516
If we take 546 away from 590, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
440 divided by 91 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 4688.4835164
Deduct 364 from 440 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.

Moving on to step 14:
When dividing 760 by 91, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 4688.48351648
Subtract 728 from 760 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 4688.48351648 with a remainder of 3.2e-08.
