We're dividing 374312 by 75 
We want to divide 374312 by 75.

Step 1:
If we divide 3 by 75, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 75

Advancing to step 2:
The number 75 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 75

On to step 3:
75 can be fit into 374 4 times, resulting in a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 300 from 374 leaves us with 74.
Bring next digit (3) of the dividend behind the 74 and repeat the process: 743 / 75

Step 4:
75 can be fit into 743 9 times, resulting in a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we subtract 675 from 743, we get 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 75

On to step 5:
If we divide 681 by 75, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 499.0
Subtracting 675 from 681 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 75

Step 6:
When dividing 62 by 75, we get 0 with a remainder of 62.
The next digit of our result is 0. 
Result so far: 4990.0
If we take 0 away from 62, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 7:
If we divide 620 by 75, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 4990.8
Deduct 600 from 620 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 75 fits into 200 2 times, leaving a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 4990.82
Subtracting 150 from 200 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 4990.826
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 75, we get 6 and a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 4990.8266
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 4990.8266, with a leftover of 0.0005.
