We divide 402233 by 20
We want to divide 402233 by 20.

Let's proceed to step 1:
20 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 20

Step 2:
If we divide 40 by 20, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 40 away from 40, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 20

Going ahead to step 3:
The number 20 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 2, we end up with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 20

Moving on to step 4:
22 divided by 20 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 201.0
The remainder is 2 after subtracting 20 from 22.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 20

Going ahead to step 5:
If we divide 23 by 20, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 2011.0
If we subtract 20 from 23, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 20

On to step 6:
20 goes into 33 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 20111.0
The remainder is 13 after subtracting 20 from 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
130 divided by 20 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 20111.6
Subtract 120 from 130 to get 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:
If we divide 100 by 20, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 20111.65
Subtract 100 from 100 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.

Let's proceed to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20111.65
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.

On to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20111.65
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.

Our division results in 20111.65 with a remaining 0.0.
