875155 ÷ 20 
Let's see how many times 20 fits into 875155.

On to step 1:
20 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 20

Moving on to step 2:
When dividing 87 by 20, we get 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 80 from 87 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 20

Going ahead to step 3:
The number 20 fits into 75 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
The remainder is 15 after subtracting 60 from 75.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 20

Moving on to step 4:
When dividing 151 by 20, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 437.0
Subtracting 140 from 151 leaves us with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 20

Going ahead to step 5:
115 divided by 20 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 4375.0
The remainder is 15 after subtracting 100 from 115.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 20

Advancing to step 6:
20 goes into 155 7 times with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 43757.0
If we subtract 140 from 155, we 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.

Let's proceed to step 7:
20 can be fit into 150 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 43757.7
Subtract 140 from 150 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.

Step 8:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 43757.75
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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 43757.75
Subtracting 0 from 0 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.

On to step 10:
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: 43757.75
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.

The final outcome is 43757.75, with a leftover of 0.0.
