Let's divide 478867 by 20
We're looking to find how many times 20 goes into 478867.

Step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 20

On to step 2:
When dividing 47 by 20, we get 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 40 from 47 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 20

On to step 3:
If we divide 78 by 20, we get 3 and a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 60 away from 78, we end up with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 20

Step 4:
20 goes into 188 9 times with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 239.0
Deduct 180 from 188 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 20

Advancing to step 5:
If we divide 86 by 20, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 2394.0
Subtracting 80 from 86 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 20

Advancing to step 6:
20 goes into 67 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 23943.0
If we subtract 60 from 67, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
20 can be fit into 70 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 23943.3
Subtract 60 from 70 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.

On to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 23943.35
Subtract 100 from 100 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.

Moving 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: 23943.35
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.

Going ahead to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 23943.35
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 final result is 23943.35 with a remainder of 0.0.
