Let's divide 378040 by 75
We want to divide 378040 by 75.

Going ahead 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
Subtract 0 from 3 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 75

Step 2:
75 goes into 37 0 times with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 75

Advancing to step 3:
When dividing 378 by 75, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 375 from 378 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 75

On to step 4:
75 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 75

On to step 5:
304 divided by 75 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 504.0
If we subtract 300 from 304, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 75

On to step 6:
The number 75 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 5040.0
Subtract 0 from 40 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.

On to step 7:
400 divided by 75 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 5040.5
Subtract 375 from 400 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.

On to step 8:
When dividing 250 by 75, we get 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 5040.53
The remainder is 25 after subtracting 225 from 250.
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 9:
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: 5040.533
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 result is 5040.533 with a remainder of 0.0025.
