We're dividing 846381 by 20 
Let's see how many times 20 fits into 846381.

Going ahead to step 1:
20 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 20

Step 2:
When dividing 84 by 20, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 80 from 84 leaves us with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 20

Going ahead to step 3:
The number 20 fits into 46 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 40 from 46 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 20

Going ahead to step 4:
20 can be fit into 63 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 423.0
If we subtract 60 from 63, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 20

On to step 5:
The number 20 fits into 38 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 4231.0
Subtract 20 from 38 to get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 20

Moving on to step 6:
20 goes into 181 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 42319.0
If we subtract 180 from 181, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
20 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 42319.0
If we take 0 away from 10, we end up 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.

Going ahead to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 42319.05
If we subtract 100 from 100, we 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:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 42319.05
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:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42319.05
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.

The final outcome is 42319.05, with a leftover of 0.0.
