14364140 ÷ 20 
The aim is to understand the frequency of 20 in 14364140.

Step 1:
1 divided by 20 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 20

Moving on to step 2:
If we divide 14 by 20, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 20

Moving on to step 3:
The number 20 fits into 143 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 140 from 143 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 20

Going ahead to step 4:
20 goes into 36 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 20 from 36, we get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 20

Going ahead to step 5:
If we divide 164 by 20, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 718.0
The remainder is 4 after subtracting 160 from 164.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 20

Moving on to step 6:
The number 20 fits into 41 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 7182.0
Subtracting 40 from 41 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 20

Advancing to step 7:
20 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 71820.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 20

Moving on to step 8:
When dividing 140 by 20, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 718207.0
The remainder is 0 after subtracting 140 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 718207.0
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.

Advancing to step 10:
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: 718207.0
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.

After the division, we end up with 718207.0 and a remainder of 0.0.
