886389 ÷ 20 
We want to divide 886389 by 20.

Going ahead to step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 20

On to step 2:
20 goes into 88 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 80 from 88, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 20

Step 3:
86 divided by 20 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtract 80 from 86 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 20

Advancing to step 4:
If we divide 63 by 20, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 443.0
If we take 60 away from 63, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 20

Advancing to step 5:
20 goes into 38 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 4431.0
Subtract 20 from 38 to get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 20

Going ahead to step 6:
20 can be fit into 189 9 times, resulting in a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 44319.0
The remainder is 9 after subtracting 180 from 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
20 goes into 90 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 44319.4
The remainder is 10 after subtracting 80 from 90.
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:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 44319.45
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.

Advancing to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 44319.45
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.

On 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: 44319.45
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.

The final outcome is 44319.45, with a leftover of 0.0.
