We're dividing 313512 by 75 
Let's see how many times 75 fits into 313512.

Let's proceed to step 1:
3 divided by 75 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 75

Step 2:
If we divide 31 by 75, we get 0 and a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 75

On to step 3:
75 can be fit into 313 4 times, resulting in a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 300 from 313 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 75

On to step 4:
75 goes into 135 1 times with a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we subtract 75 from 135, we get 60.
Take the next digit (1) from the dividend and append it to 60, then repeat: 601 / 75

Advancing to step 5:
The number 75 fits into 601 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 418.0
If we take 600 away from 601, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 75

Going ahead to step 6:
The number 75 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 4180.0
Subtract 0 from 12 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
75 goes into 120 1 times with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 4180.1
Subtracting 75 from 120 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 8:
The number 75 fits into 450 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 4180.16
Subtracting 450 from 450 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 75 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4180.16
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 75, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4180.16
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 4180.16 and a remainder of 0.0.
