Let's divide 812342 by 20
We're looking to find how many times 20 goes into 812342.

Let's proceed to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 20

Let's proceed to step 2:
The number 20 fits into 81 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 80 from 81, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 20

Going ahead to step 3:
When dividing 12 by 20, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 20

Going ahead to step 4:
If we divide 123 by 20, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 406.0
If we take 120 away from 123, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 20

Let's proceed to step 5:
The number 20 fits into 34 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 4061.0
If we subtract 20 from 34, we get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 20

Advancing to step 6:
20 goes into 142 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 40617.0
Deduct 140 from 142 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 20, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 40617.1
The remainder is 0 after subtracting 20 from 20.
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:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40617.1
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.

Step 9:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40617.1
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.

Our division results in 40617.1 with a remaining 0.0.
