527905 ÷ 91 
The aim is to understand the frequency of 91 in 527905.

Going ahead to step 1:
The number 91 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 91

Advancing to step 2:
52 divided by 91 is 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 91

Advancing to step 3:
91 can be fit into 527 5 times, resulting in a remainder of 72.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 72 after subtracting 455 from 527.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 91

Moving on to step 4:
When dividing 729 by 91, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
If we subtract 728 from 729, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 91

On to step 5:
When dividing 10 by 91, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 580.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 91

Step 6:
91 goes into 105 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 5801.0
If we take 91 away from 105, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
91 can be fit into 140 1 times, resulting in a remainder of 49.
The next digit of our result is 1. 
Result so far: 5801.1
Deduct 91 from 140 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 8:
91 can be fit into 490 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 5801.15
Deduct 455 from 490 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
91 goes into 350 3 times with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 5801.153
Subtract 273 from 350 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 10:
91 goes into 770 8 times with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 5801.1538
The remainder is 42 after subtracting 728 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
91 goes into 420 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 5801.15384
Deduct 364 from 420 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
If we divide 560 by 91, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 5801.153846
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
91 goes into 140 1 times with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 5801.1538461
Subtract 91 from 140 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 14:
490 divided by 91 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 5801.15384615
If we take 455 away from 490, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 5801.15384615, and the remainder is 3.5e-08.
