455683 divided by 20 
We're looking to find how many times 20 goes into 455683.

Going ahead to step 1:
4 divided by 20 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 20

Moving on to step 2:
20 goes into 45 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 40 from 45, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 20

On to step 3:
If we divide 55 by 20, we get 2 and a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 40 from 55 to get 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 20

Going ahead to step 4:
When dividing 156 by 20, we get 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 227.0
If we take 140 away from 156, we end up with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 20

Let's proceed to step 5:
If we divide 168 by 20, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 2278.0
If we subtract 160 from 168, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 20

Let's proceed to step 6:
When dividing 83 by 20, we get 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 22784.0
Subtract 80 from 83 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 22784.1
Deduct 20 from 30 and we're left 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.

Let's proceed to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 22784.15
If we take 100 away from 100, 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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22784.15
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:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22784.15
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.

After the division, we end up with 22784.15 and a remainder of 0.0.
