We look at the division of 634039 by 75 
We're looking to find how many times 75 goes into 634039.

On to step 1:
75 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 75

Going ahead to step 2:
When dividing 63 by 75, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Bring next digit (4) of the dividend behind the 63 and repeat the process: 634 / 75

Moving on to step 3:
75 can be fit into 634 8 times, resulting in a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 34 after subtracting 600 from 634.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 75

On to step 4:
The number 75 fits into 340 4 times, leaving a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 84.0
The remainder is 40 after subtracting 300 from 340.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 75

Step 5:
If we divide 403 by 75, we get 5 and a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 845.0
Subtract 375 from 403 to get 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 75

Advancing to step 6:
75 goes into 289 3 times with a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 8453.0
If we subtract 225 from 289, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
If we divide 640 by 75, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 8453.8
If we subtract 600 from 640, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
75 can be fit into 400 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 8453.85
If we subtract 375 from 400, 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.

Step 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 8453.853
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 10:
When dividing 250 by 75, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 8453.8533
Subtract 225 from 250 to 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.

The quotient of the division is 8453.8533, and the remainder is 0.00025.
