We divide 635809 by 75
We want to figure out the number of times 635809 can be divided by 75.

Step 1:
The number 75 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 75

On to step 2:
The number 75 fits into 63 0 times, leaving a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 75

Advancing to step 3:
635 divided by 75 is 8 with a remainder of 35.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 600 from 635, we get 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 75

Moving on to step 4:
When dividing 358 by 75, we get 4 with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Subtract 300 from 358 to get 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 75

Let's proceed to step 5:
When dividing 580 by 75, we get 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 847.0
Subtract 525 from 580 to get 55.
Include the next digit (9) from the dividend after 55, then repeat: 559 / 75

Step 6:
If we divide 559 by 75, we get 7 and a remainder of 34.
The next digit of our result is 7. 
Result so far: 8477.0
Subtracting 525 from 559 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
75 goes into 340 4 times with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 8477.4
Subtract 300 from 340 to 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.

Advancing to step 8:
75 goes into 400 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 8477.45
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.

On to step 9:
75 goes into 250 3 times with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 8477.453
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.

Let's proceed to step 10:
If we divide 250 by 75, we get 3 and a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 8477.4533
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.

The final outcome is 8477.4533, with a leftover of 0.00025.
