We divide 817873 by 20
Let's see how many times 20 fits into 817873.

Going ahead to step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 20

Advancing to step 2:
When dividing 81 by 20, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 1 after subtracting 80 from 81.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 20

Advancing to step 3:
If we divide 17 by 20, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 20

Moving on to step 4:
When dividing 178 by 20, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 408.0
Subtract 160 from 178 to get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 20

Let's proceed to step 5:
If we divide 187 by 20, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 4089.0
If we take 180 away from 187, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 20

Let's proceed to step 6:
When dividing 73 by 20, we get 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 40893.0
If we take 60 away from 73, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
When dividing 130 by 20, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 40893.6
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:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 40893.65
The remainder is 0 after subtracting 100 from 100.
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 40893.65
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.

Going ahead to step 10:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40893.65
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.

In conclusion, the division gives 40893.65 with a balance of 0.0.
