We're dividing 734199 by 91 
The aim is to understand the frequency of 91 in 734199.

Moving on to step 1:
91 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 91

Moving on to step 2:
If we divide 73 by 91, we get 0 and a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Fetch the next digit (4) from the dividend, attach it to 73 and continue: 734 / 91

Advancing to step 3:
When dividing 734 by 91, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 728 from 734 to get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 91

Step 4:
91 can be fit into 61 0 times, resulting in a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we subtract 0 from 61, we get 61.
Fetch the next digit (9) from the dividend, attach it to 61 and continue: 619 / 91

Advancing to step 5:
619 divided by 91 is 6 with a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 806.0
If we subtract 546 from 619, we get 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 91

Advancing to step 6:
When dividing 739 by 91, we get 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 8068.0
The remainder is 11 after subtracting 728 from 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
91 can be fit into 110 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 8068.1
Deduct 91 from 110 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
190 divided by 91 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 8068.12
If we take 182 away from 190, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
If we divide 80 by 91, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 8068.12
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
800 divided by 91 is 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 8068.1208
Subtract 728 from 800 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 11:
91 goes into 720 7 times with a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 8068.12087
If we take 637 away from 720, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 12:
830 divided by 91 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 8068.120879
Subtract 819 from 830 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 13:
91 goes into 110 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 8068.1208791
If we take 91 away from 110, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
The number 91 fits into 190 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 8068.12087912
The remainder is 8 after subtracting 182 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 8068.12087912, with a leftover of 8e-09.
