107142 divided by 20 
The aim is to understand the frequency of 20 in 107142.

Advancing to step 1:
If we divide 1 by 20, we get 0 and 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.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 20

Step 2:
20 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 20

On to step 3:
The number 20 fits into 107 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 100 from 107 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 20

Step 4:
20 goes into 71 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Deduct 60 from 71 and we're left with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 20

Step 5:
20 goes into 114 5 times with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 535.0
If we take 100 away from 114, we end up with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 20

Moving on to step 6:
If we divide 142 by 20, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 5357.0
Deduct 140 from 142 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 20, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 5357.1
If we take 20 away from 20, 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.

Step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5357.1
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.

Going ahead to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5357.1
The remainder is 0 after subtracting 0 from 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 outcome is 5357.1, with a leftover of 0.0.
