We're dividing 744700 by 91 
The aim is to understand the frequency of 91 in 744700.

Advancing to step 1:
91 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 91

Let's proceed to step 2:
When dividing 74 by 91, we get 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 91

Step 3:
The number 91 fits into 744 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 728 from 744 and we're left with 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 91

On to step 4:
When dividing 167 by 91, we get 1 with a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we subtract 91 from 167, we get 76.
Append the next digit (0) from the dividend to 76 and continue with: 760 / 91

Advancing to step 5:
The number 91 fits into 760 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 818.0
If we take 728 away from 760, we end up with 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 91

Advancing to step 6:
320 divided by 91 is 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 8183.0
If we take 273 away from 320, we end up with 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 7:
470 divided by 91 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 8183.5
Deduct 455 from 470 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
91 can be fit into 150 1 times, resulting in a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 8183.51
The remainder is 59 after subtracting 91 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
If we divide 590 by 91, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 8183.516
The remainder is 44 after subtracting 546 from 590.
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 10:
If we divide 440 by 91, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 8183.5164
Subtracting 364 from 440 leaves us 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.

Advancing to step 11:
The number 91 fits into 760 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 8183.51648
The remainder is 32 after subtracting 728 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
91 goes into 320 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 8183.516483
Subtracting 273 from 320 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 13:
If we divide 470 by 91, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 8183.5164835
Subtracting 455 from 470 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
91 can be fit into 150 1 times, resulting in a remainder of 59.
The next digit of our result is 1. 
Result so far: 8183.51648351
If we take 91 away from 150, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final outcome is 8183.51648351, with a leftover of 5.9e-08.
