We're dividing 355690 by 75 
We want to divide 355690 by 75.

On to step 1:
75 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 75

On to step 2:
The number 75 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 75

Moving on to step 3:
If we divide 355 by 75, we get 4 and a remainder of 55.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 300 from 355, we get 55.
Bring next digit (6) of the dividend behind the 55 and repeat the process: 556 / 75

Step 4:
If we divide 556 by 75, we get 7 and a remainder of 31.
The next digit of our result is 7. 
Result so far: 47.0
If we take 525 away from 556, we end up with 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 75

Going ahead to step 5:
If we divide 319 by 75, we get 4 and a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 474.0
If we take 300 away from 319, we end up with 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 75

Moving on to step 6:
190 divided by 75 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 4742.0
The remainder is 40 after subtracting 150 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
75 goes into 400 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 4742.5
If we take 375 away from 400, 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.

Going ahead to step 8:
If we divide 250 by 75, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 4742.53
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.

On to step 9:
75 goes into 250 3 times with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 4742.533
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.

After the division, we end up with 4742.533 and a remainder of 0.0025.
