Let's divide 453336 by 20
Our goal is to divide 453336 by 20.

Going ahead 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
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 20

Moving on to step 2:
45 divided by 20 is 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 5 after subtracting 40 from 45.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 20

Going ahead to step 3:
When dividing 53 by 20, we get 2 with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 40 from 53 and we're left with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 20

Advancing to step 4:
The number 20 fits into 133 6 times, leaving a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 226.0
Deduct 120 from 133 and we're left with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 20

Moving on to step 5:
133 divided by 20 is 6 with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 2266.0
Deduct 120 from 133 and we're left with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 20

Moving on to step 6:
20 goes into 136 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 22666.0
Deduct 120 from 136 and we're left 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.

Going ahead to step 7:
When dividing 160 by 20, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 22666.8
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.

Let's proceed to step 8:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22666.8
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.

On to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22666.8
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.

The final outcome is 22666.8, with a leftover of 0.0.
