Let's divide 456936 by 20
We want to figure out the number of times 456936 can be divided by 20.

Advancing to step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 20

Step 2:
If we divide 45 by 20, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 5 after subtracting 40 from 45.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 20

Step 3:
20 goes into 56 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtracting 40 from 56 leaves us with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 20

On to step 4:
169 divided by 20 is 8 with a remainder of 9.
The next digit of our result is 8. 
Result so far: 228.0
If we take 160 away from 169, we end up with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 20

Step 5:
If we divide 93 by 20, we get 4 and a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 2284.0
The remainder is 13 after subtracting 80 from 93.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 20

Step 6:
When dividing 136 by 20, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 22846.0
Subtracting 120 from 136 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
20 goes into 160 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 22846.8
Deduct 160 from 160 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.

Step 8:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22846.8
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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22846.8
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.

The quotient of the division is 22846.8, and the remainder is 0.0.
