We divide 206735 by 20
The aim is to understand the frequency of 20 in 206735.

On to step 1:
When dividing 2 by 20, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 20

Going ahead to step 2:
When dividing 20 by 20, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 20 from 20 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 20

Advancing to step 3:
20 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 6, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 20

Moving on to step 4:
20 goes into 67 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 103.0
If we take 60 away from 67, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 20

Advancing to step 5:
When dividing 73 by 20, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 1033.0
Subtract 60 from 73 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 20

Advancing to step 6:
When dividing 135 by 20, we get 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 10336.0
The remainder is 15 after subtracting 120 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
150 divided by 20 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 10336.7
If we take 140 away from 150, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10336.75
Deduct 100 from 100 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.

Advancing to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10336.75
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.

Going ahead to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 10336.75
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 10336.75 and a remainder of 0.0.
