180207 ÷ 20 
We want to figure out the number of times 180207 can be divided by 20.

On to step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 20

Advancing to step 2:
If we divide 18 by 20, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 20

Going ahead to step 3:
20 goes into 180 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
If we take 180 away from 180, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 20

Going ahead to step 4:
20 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 20

Moving on to step 5:
If we divide 20 by 20, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 901.0
Deduct 20 from 20 and we're left with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 20

Advancing to step 6:
20 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 9010.0
Deduct 0 from 7 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
When dividing 70 by 20, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 9010.3
The remainder is 10 after subtracting 60 from 70.
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.
The next digit of our result is 5. 
Result so far: 9010.35
If we subtract 100 from 100, 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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9010.35
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.

On to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9010.35
Subtract 0 from 0 to 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.

After the division, we end up with 9010.35 and a remainder of 0.0.
