We're dividing 874815 by 20 
We want to figure out the number of times 874815 can be divided by 20.

Moving on to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 20

Advancing to step 2:
When dividing 87 by 20, we get 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 80 from 87 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 20

Advancing to step 3:
20 can be fit into 74 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
The remainder is 14 after subtracting 60 from 74.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 20

Step 4:
20 goes into 148 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 437.0
Deduct 140 from 148 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 20

Step 5:
When dividing 81 by 20, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4374.0
If we subtract 80 from 81, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 20

On to step 6:
20 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 43740.0
Subtract 0 from 15 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
When dividing 150 by 20, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 43740.7
If we take 140 away from 150, we end up 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: 43740.75
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.

Let's proceed to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 43740.75
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.

On to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43740.75
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 quotient of the division is 43740.75, and the remainder is 0.0.
