Let's divide 866440 by 20
Our goal is to divide 866440 by 20.

On 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
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 20

Advancing to step 2:
20 can be fit into 86 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 6 after subtracting 80 from 86.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 20

On to step 3:
The number 20 fits into 66 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 6 after subtracting 60 from 66.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 20

Advancing to step 4:
64 divided by 20 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 433.0
Deduct 60 from 64 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 20

Going ahead to step 5:
When dividing 44 by 20, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 4332.0
Deduct 40 from 44 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 20

Going ahead to step 6:
The number 20 fits into 40 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 43322.0
If we subtract 40 from 40, 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.

On to step 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 43322.0
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 8:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 43322.0
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.

The quotient of the division is 43322.0, and the remainder is 0.0.
