We're dividing 88917226 by 324 
The aim is to understand the frequency of 324 in 88917226.

On to step 1:
324 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 324

Moving on to step 2:
324 goes into 88 0 times with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 324

Going ahead to step 3:
324 can be fit into 889 2 times, resulting in a remainder of 241.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 648 from 889 to get 241.
Grab the next digit (1) from the dividend, add it to 241, then carry on: 2411 / 324

Advancing to step 4:
324 can be fit into 2411 7 times, resulting in a remainder of 143.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 2268 from 2411 leaves us with 143.
Append the next digit (7) from the dividend to 143 and continue with: 1437 / 324

Advancing to step 5:
When dividing 1437 by 324, we get 4 with a remainder of 141.
The number 4 becomes the next digit in our result. 
Result so far: 274.0
Deduct 1296 from 1437 and we're left with 141.
Append the next digit (2) from the dividend to 141 and continue with: 1412 / 324

On to step 6:
324 goes into 1412 4 times with a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 2744.0
The remainder is 116 after subtracting 1296 from 1412.
Fetch the next digit (2) from the dividend, attach it to 116 and continue: 1162 / 324

Going ahead to step 7:
When dividing 1162 by 324, we get 3 with a remainder of 190.
Put 3 as the next digit of the answer. 
Result so far: 27443.0
If we take 972 away from 1162, we end up with 190.
Fetch the next digit (6) from the dividend, attach it to 190 and continue: 1906 / 324

On to step 8:
When dividing 1906 by 324, we get 5 with a remainder of 286.
Write down 5 as next digit of the result. 
Result so far: 274435.0
If we take 1620 away from 1906, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 9:
2860 divided by 324 is 8 with a remainder of 268.
Record the quotient 8 as the next digit in the result. 
Result so far: 274435.8
If we take 2592 away from 2860, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 10:
When dividing 2680 by 324, we get 8 with a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 274435.88
If we take 2592 away from 2680, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 274435.88 and a remainder of 0.088.
