We divide 146080 by 20
We want to figure out the number of times 146080 can be divided by 20.

Let's proceed to step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 20

Going ahead to step 2:
14 divided by 20 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 20

On to step 3:
146 divided by 20 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 140 from 146 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 20

Step 4:
60 divided by 20 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtract 60 from 60 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 20

Step 5:
8 divided by 20 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 730.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 20

On to step 6:
If we divide 80 by 20, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 7304.0
The remainder is 0 after subtracting 80 from 80.
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 7:
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: 7304.0
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.

On to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7304.0
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 7304.0 and a remainder of 0.0.
