We divide 878382 by 20
We want to figure out the number of times 878382 can be divided by 20.

Step 1:
The number 20 fits into 8 0 times, leaving 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.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 20

Going ahead to step 2:
20 goes into 87 4 times with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 80 from 87, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 20

Step 3:
20 can be fit into 78 3 times, resulting in a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 60 from 78 leaves us with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 20

Going ahead to step 4:
The number 20 fits into 183 9 times, leaving a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 439.0
Subtract 180 from 183 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 20

Going ahead to step 5:
If we divide 38 by 20, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 4391.0
If we take 20 away from 38, we end up with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 20

Moving on to step 6:
When dividing 182 by 20, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 43919.0
If we subtract 180 from 182, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 goes into 20 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 43919.1
If we take 20 away from 20, 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.

Going ahead to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43919.1
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.

Advancing 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: 43919.1
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.

The final result is 43919.1 with a remainder of 0.0.
