Let's divide 117144 by 20
The aim is to understand the frequency of 20 in 117144.

Step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 20

Going ahead to step 2:
The number 20 fits into 11 0 times, leaving a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 20

Let's proceed to step 3:
The number 20 fits into 117 5 times, leaving a remainder of 17.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 17 after subtracting 100 from 117.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 20

Advancing to step 4:
20 can be fit into 171 8 times, resulting in a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 58.0
If we take 160 away from 171, we end up with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 20

Step 5:
The number 20 fits into 114 5 times, leaving a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 585.0
The remainder is 14 after subtracting 100 from 114.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 20

Let's proceed to step 6:
20 goes into 144 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 5857.0
Deduct 140 from 144 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 20, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 5857.2
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5857.2
Subtracting 0 from 0 leaves us 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.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5857.2
If we take 0 away from 0, 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.

The final result is 5857.2 with a remainder of 0.0.
