112568 ÷ 20 
The aim is to understand the frequency of 20 in 112568.

Advancing to step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 20

On to step 2:
If we divide 11 by 20, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 20

Advancing to step 3:
When dividing 112 by 20, we get 5 with a remainder of 12.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 100 from 112 leaves us with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 20

Step 4:
The number 20 fits into 125 6 times, leaving a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we take 120 away from 125, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 20

On to step 5:
When dividing 56 by 20, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 562.0
Deduct 40 from 56 and we're left with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 20

On to step 6:
When dividing 168 by 20, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 5628.0
Deduct 160 from 168 and we're left 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.

Advancing to step 7:
20 goes into 80 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 5628.4
If we take 80 away from 80, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5628.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5628.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 5628.4 and a remainder of 0.0.
