We divide 877185 by 20
Let's see how many times 20 fits into 877185.

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
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 20

Going ahead to step 2:
20 goes into 87 4 times with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 80 from 87, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 20

Advancing to step 3:
The number 20 fits into 77 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we take 60 away from 77, we end up with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 20

On to step 4:
When dividing 171 by 20, we get 8 with a remainder of 11.
The next digit of our result is 8. 
Result so far: 438.0
Subtracting 160 from 171 leaves us with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 20

Advancing to step 5:
If we divide 118 by 20, we get 5 and a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 4385.0
Deduct 100 from 118 and we're left with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 20

Going ahead to step 6:
If we divide 185 by 20, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 43859.0
The remainder is 5 after subtracting 180 from 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
20 can be fit into 50 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 43859.2
Subtracting 40 from 50 leaves us 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.

Moving on to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 43859.25
Deduct 100 from 100 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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43859.25
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.

Let's proceed to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43859.25
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.

The quotient of the division is 43859.25, and the remainder is 0.0.
