378497 ÷ 75 
Let's see how many times 75 fits into 378497.

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
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 75

Let's proceed to 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
Subtracting 0 from 37 leaves us with 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 75

Let's proceed to step 3:
The number 75 fits into 378 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 375 from 378 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 75

Moving on to step 4:
75 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 50.0
If we subtract 0 from 34, we get 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 75

Moving on to step 5:
349 divided by 75 is 4 with a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 504.0
Subtracting 300 from 349 leaves us with 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 75

Going ahead to step 6:
75 goes into 497 6 times with a remainder of 47.
The number 6 becomes the next digit in our result. 
Result so far: 5046.0
Subtract 450 from 497 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
75 goes into 470 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 5046.6
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.

Let's proceed to step 8:
200 divided by 75 is 2 with a remainder of 50.
The next digit of our result is 2. 
Result so far: 5046.62
Deduct 150 from 200 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.

Moving on to step 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 5046.626
Subtract 450 from 500 to 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.

Advancing 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: 5046.6266
Subtracting 450 from 500 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.

The final outcome is 5046.6266, with a leftover of 0.0005.
