Let's divide 776598 by 91
The aim is to understand the frequency of 91 in 776598.

Going ahead to step 1:
91 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 91

Advancing to step 2:
If we divide 77 by 91, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 91

Advancing to step 3:
91 goes into 776 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 728 from 776 and we're left with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 91

Step 4:
91 can be fit into 485 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 85.0
If we take 455 away from 485, we end up with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 91

Step 5:
91 goes into 309 3 times with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 853.0
The remainder is 36 after subtracting 273 from 309.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 91

Moving on to step 6:
The number 91 fits into 368 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 8534.0
Subtracting 364 from 368 leaves us 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.

Going ahead to step 7:
91 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8534.0
Subtract 0 from 40 to 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 8:
91 can be fit into 400 4 times, resulting in a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 8534.04
If we take 364 away from 400, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
The number 91 fits into 360 3 times, leaving a remainder of 87.
The next digit of our result is 3. 
Result so far: 8534.043
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.

Let's proceed to step 10:
The number 91 fits into 870 9 times, leaving a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 8534.0439
If we subtract 819 from 870, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
510 divided by 91 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 8534.04395
Deduct 455 from 510 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 12:
When dividing 550 by 91, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 8534.043956
If we take 546 away from 550, we end up 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.

On to step 13:
The number 91 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8534.043956
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
If we divide 400 by 91, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 8534.04395604
Subtracting 364 from 400 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 8534.04395604 with a remaining 3.6e-08.
