873821 divided by 20 
We want to divide 873821 by 20.

Advancing to step 1:
20 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 20

On to step 2:
The number 20 fits into 87 4 times, leaving a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 80 from 87 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 20

On to step 3:
20 can be fit into 73 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we take 60 away from 73, we end up with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 20

Let's proceed to step 4:
When dividing 138 by 20, we get 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 436.0
If we subtract 120 from 138, we get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 20

Going ahead to step 5:
If we divide 182 by 20, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 4369.0
The remainder is 2 after subtracting 180 from 182.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 20

Step 6:
When dividing 21 by 20, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 43691.0
The remainder is 1 after subtracting 20 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 20 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 43691.0
Deduct 0 from 10 and we're left 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.

Step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 43691.05
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.

Going ahead to 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: 43691.05
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.

Moving on to step 10:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43691.05
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 quotient of the division is 43691.05, and the remainder is 0.0.
