We're dividing 636487 by 75 
We want to divide 636487 by 75.

Going ahead to step 1:
75 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 75

Let's proceed to step 2:
63 divided by 75 is 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 75

Step 3:
75 can be fit into 636 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 600 away from 636, we end up with 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 75

Going ahead to step 4:
When dividing 364 by 75, we get 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtract 300 from 364 to get 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 75

Advancing to step 5:
75 can be fit into 648 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 848.0
If we subtract 600 from 648, we get 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 75

Advancing to step 6:
If we divide 487 by 75, we get 6 and a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 8486.0
Subtracting 450 from 487 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
When dividing 370 by 75, we get 4 with a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 8486.4
If we take 300 away from 370, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
700 divided by 75 is 9 with a remainder of 25.
The next digit of our result is 9. 
Result so far: 8486.49
If we take 675 away from 700, 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.

Advancing to step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 8486.493
Deduct 225 from 250 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 10:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 8486.4933
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.

The quotient of the division is 8486.4933, and the remainder is 0.00025.
