22521 divided by 68 
The aim is to understand the frequency of 68 in 22521.

Moving on to step 1:
2 divided by 68 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 68

Step 2:
22 divided by 68 is 0 with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 68

Moving on to step 3:
68 goes into 225 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 204 from 225 leaves us with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 68

Let's proceed to step 4:
68 goes into 212 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 204 from 212 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 68

Let's proceed to step 5:
68 goes into 81 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 331.0
Subtract 68 from 81 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 6:
68 can be fit into 130 1 times, resulting in a remainder of 62.
The next digit of our result is 1. 
Result so far: 331.1
Subtracting 68 from 130 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
68 goes into 620 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 331.19
Subtracting 612 from 620 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
80 divided by 68 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 331.191
Subtracting 68 from 80 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
The number 68 fits into 120 1 times, leaving a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 331.1911
The remainder is 52 after subtracting 68 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 331.1911 with a balance of 0.00052.
