We're dividing 23310021 by 527 
The aim is to understand the frequency of 527 in 23310021.

Step 1:
The number 527 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 527

Advancing to step 2:
23 divided by 527 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 527

Moving on to step 3:
527 can be fit into 233 0 times, resulting in a remainder of 233.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 233 and we're left with 233.
Include the next digit (1) from the dividend after 233, then repeat: 2331 / 527

Moving on to step 4:
If we divide 2331 by 527, we get 4 and a remainder of 223.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 2108 from 2331 to get 223.
Append the next digit (0) from the dividend to 223 and continue with: 2230 / 527

Moving on to step 5:
The number 527 fits into 2230 4 times, leaving a remainder of 122.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtracting 2108 from 2230 leaves us with 122.
Append the next digit (0) from the dividend to 122 and continue with: 1220 / 527

On to step 6:
If we divide 1220 by 527, we get 2 and a remainder of 166.
Write down 2 as next digit of the result. 
Result so far: 442.0
If we subtract 1054 from 1220, we get 166.
Bring next digit (2) of the dividend behind the 166 and repeat the process: 1662 / 527

Advancing to step 7:
If we divide 1662 by 527, we get 3 and a remainder of 81.
The number 3 becomes the next digit in our result. 
Result so far: 4423.0
Deduct 1581 from 1662 and we're left with 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 527

Going ahead to step 8:
If we divide 811 by 527, we get 1 and a remainder of 284.
The next digit of our result is 1. 
Result so far: 44231.0
The remainder is 284 after subtracting 527 from 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 9:
When dividing 2840 by 527, we get 5 with a remainder of 205.
The next digit of our result is 5. 
Result so far: 44231.5
Subtract 2635 from 2840 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 10:
The number 527 fits into 2050 3 times, leaving a remainder of 469.
Put 3 as the next digit of the answer. 
Result so far: 44231.53
Deduct 1581 from 2050 and we're left with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Going ahead to step 11:
4690 divided by 527 is 8 with a remainder of 474.
Use 8 as the next digit of our solution. 
Result so far: 44231.538
Subtract 4216 from 4690 to get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 12:
The number 527 fits into 4740 8 times, leaving a remainder of 524.
Record the quotient 8 as the next digit in the result. 
Result so far: 44231.5388
Subtracting 4216 from 4740 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

The final outcome is 44231.5388, with a leftover of 0.00524.
