845383 divided by 20 
We want to divide 845383 by 20.

On to step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 20

Going ahead to step 2:
If we divide 84 by 20, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 80 from 84, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 20

Step 3:
The number 20 fits into 45 2 times, leaving a remainder of 5.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 40 from 45 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 20

Going ahead to step 4:
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: 422.0
Subtract 40 from 53 to get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 20

Going ahead to step 5:
When dividing 138 by 20, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 4226.0
Subtracting 120 from 138 leaves us with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 20

On to step 6:
20 goes into 183 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 42269.0
If we take 180 away from 183, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 20 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 42269.1
Subtracting 20 from 30 leaves us 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 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 42269.15
Subtracting 100 from 100 leaves us 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 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42269.15
Deduct 0 from 0 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 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42269.15
Subtracting 0 from 0 leaves us 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.

Our division results in 42269.15 with a remaining 0.0.
