Let's divide 868379 by 20
We want to figure out the number of times 868379 can be divided by 20.

Let's proceed to 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
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 20

On to step 2:
The number 20 fits into 86 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 4.0
If we take 80 away from 86, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 20

Advancing to step 3:
20 goes into 68 3 times with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
The remainder is 8 after subtracting 60 from 68.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 20

Let's proceed to step 4:
When dividing 83 by 20, we get 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 434.0
If we take 80 away from 83, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 20

Moving on to step 5:
20 can be fit into 37 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 4341.0
The remainder is 17 after subtracting 20 from 37.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 20

Let's proceed to step 6:
If we divide 179 by 20, we get 8 and a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 43418.0
Subtract 160 from 179 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
20 can be fit into 190 9 times, resulting in a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 43418.9
Deduct 180 from 190 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:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 43418.95
Subtracting 100 from 100 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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 43418.95
Deduct 0 from 0 and we're left 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.
Use 0 as the next digit of our solution. 
Result so far: 43418.95
If we subtract 0 from 0, 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.

After the division, we end up with 43418.95 and a remainder of 0.0.
