739834 ÷ 91 
The aim is to understand the frequency of 91 in 739834.

On to step 1:
If we divide 7 by 91, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 91

Moving on to step 2:
When dividing 73 by 91, we get 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 91

Advancing to step 3:
If we divide 739 by 91, we get 8 and a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 728 from 739 to get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 91

Going ahead to step 4:
118 divided by 91 is 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 81.0
If we take 91 away from 118, we end up with 27.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 91

Moving on to step 5:
When dividing 273 by 91, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 813.0
Subtract 273 from 273 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 91

Step 6:
4 divided by 91 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 8130.0
Deduct 0 from 4 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
91 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 8130.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
91 can be fit into 400 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 8130.04
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
The number 91 fits into 360 3 times, leaving a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 8130.043
Subtracting 273 from 360 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 10:
When dividing 870 by 91, we get 9 with a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 8130.0439
If we take 819 away from 870, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 11:
510 divided by 91 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 8130.04395
Subtract 455 from 510 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 12:
If we divide 550 by 91, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 8130.043956
If we subtract 546 from 550, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
When dividing 40 by 91, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8130.043956
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
400 divided by 91 is 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 8130.04395604
Subtract 364 from 400 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 8130.04395604 with a balance of 3.6e-08.
