146580 divided by 20 
We're looking to find how many times 20 goes into 146580.

On to step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 20

Going ahead to step 2:
The number 20 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 20

Moving on to step 3:
20 can be fit into 146 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 140 from 146, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 20

On to step 4:
20 goes into 65 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 73.0
Subtract 60 from 65 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 20

On to step 5:
The number 20 fits into 58 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 732.0
Deduct 40 from 58 and we're left with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 20

Let's proceed to step 6:
When dividing 180 by 20, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 7329.0
The remainder is 0 after subtracting 180 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
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: 7329.0
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.

Moving on to step 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7329.0
If we take 0 away from 0, 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.

The quotient of the division is 7329.0, and the remainder is 0.0.
