We look at the division of 91004365 by 527 
The aim is to understand the frequency of 527 in 91004365.

Moving on to step 1:
If we divide 9 by 527, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 527

Going ahead to step 2:
When dividing 91 by 527, we get 0 with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Fetch the next digit (0) from the dividend, attach it to 91 and continue: 910 / 527

Going ahead to step 3:
527 goes into 910 1 times with a remainder of 383.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 527 from 910 leaves us with 383.
Grab the next digit (0) from the dividend, add it to 383, then carry on: 3830 / 527

Moving on to step 4:
The number 527 fits into 3830 7 times, leaving a remainder of 141.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 141 after subtracting 3689 from 3830.
Grab the next digit (4) from the dividend, add it to 141, then carry on: 1414 / 527

Let's proceed to step 5:
527 goes into 1414 2 times with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Deduct 1054 from 1414 and we're left with 360.
Take the next digit (3) from the dividend and append it to 360, then repeat: 3603 / 527

Going ahead to step 6:
The number 527 fits into 3603 6 times, leaving a remainder of 441.
The number 6 becomes the next digit in our result. 
Result so far: 1726.0
Deduct 3162 from 3603 and we're left with 441.
Bring next digit (6) of the dividend behind the 441 and repeat the process: 4416 / 527

Step 7:
If we divide 4416 by 527, we get 8 and a remainder of 200.
The number 8 becomes the next digit in our result. 
Result so far: 17268.0
If we take 4216 away from 4416, we end up with 200.
Include the next digit (5) from the dividend after 200, then repeat: 2005 / 527

Step 8:
If we divide 2005 by 527, we get 3 and a remainder of 424.
Record the quotient 3 as the next digit in the result. 
Result so far: 172683.0
The remainder is 424 after subtracting 1581 from 2005.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 9:
527 goes into 4240 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 172683.8
Deduct 4216 from 4240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
527 can be fit into 240 0 times, resulting in a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 172683.8
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 11:
When dividing 2400 by 527, we get 4 with a remainder of 292.
Use 4 as the next digit of our solution. 
Result so far: 172683.804
If we subtract 2108 from 2400, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 12:
When dividing 2920 by 527, we get 5 with a remainder of 285.
The number 5 becomes the next digit in our result. 
Result so far: 172683.8045
The remainder is 285 after subtracting 2635 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 13:
527 goes into 2850 5 times with a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 172683.80455
If we subtract 2635 from 2850, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

The final result is 172683.80455 with a remainder of 0.000215.
