We look at the division of 842800 by 75 
We're looking to find how many times 75 goes into 842800.

On to step 1:
The number 75 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 75

Let's proceed to step 2:
75 can be fit into 84 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 75 away from 84, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 75

Step 3:
92 divided by 75 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 75 from 92 and we're left with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 75

On to step 4:
75 goes into 178 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Deduct 150 from 178 and we're left with 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 75

Let's proceed to step 5:
When dividing 280 by 75, we get 3 with a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 1123.0
Subtracting 225 from 280 leaves us with 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 75

Step 6:
If we divide 550 by 75, we get 7 and a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 11237.0
Deduct 525 from 550 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
75 goes into 250 3 times with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 11237.3
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 11237.33
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 11237.33 with a remaining 0.025.
