We look at the division of 340772 by 75 
We're looking to find how many times 75 goes into 340772.

Step 1:
When dividing 3 by 75, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 75

Going ahead to step 2:
The number 75 fits into 34 0 times, leaving a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 75

Advancing to step 3:
The number 75 fits into 340 4 times, leaving a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 300 from 340 leaves us with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 75

Let's proceed to step 4:
407 divided by 75 is 5 with a remainder of 32.
The next digit of our result is 5. 
Result so far: 45.0
Deduct 375 from 407 and we're left with 32.
Grab the next digit (7) from the dividend, add it to 32, then carry on: 327 / 75

Advancing to step 5:
327 divided by 75 is 4 with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 454.0
If we take 300 away from 327, we end up with 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 75

On to step 6:
The number 75 fits into 272 3 times, leaving a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 4543.0
Subtracting 225 from 272 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 7:
The number 75 fits into 470 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 4543.6
Subtract 450 from 470 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
75 goes into 200 2 times with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 4543.62
If we take 150 away from 200, we end up 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.

Let's proceed to step 9:
When dividing 500 by 75, we get 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 4543.626
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
500 divided by 75 is 6 with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 4543.6266
Deduct 450 from 500 and we're left 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.

The final outcome is 4543.6266, with a leftover of 0.0005.
