Let's divide 671980 by 75
We want to figure out the number of times 671980 can be divided by 75.

Let's proceed to step 1:
When dividing 6 by 75, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 75

Moving on to step 2:
If we divide 67 by 75, we get 0 and a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 75

On to step 3:
If we divide 671 by 75, we get 8 and a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 600 from 671, we get 71.
Take the next digit (9) from the dividend and append it to 71, then repeat: 719 / 75

Going ahead to step 4:
75 goes into 719 9 times with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Deduct 675 from 719 and we're left with 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 75

Let's proceed to step 5:
75 goes into 448 5 times with a remainder of 73.
The number 5 becomes the next digit in our result. 
Result so far: 895.0
Subtract 375 from 448 to get 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 75

Moving on to step 6:
The number 75 fits into 730 9 times, leaving a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 8959.0
If we subtract 675 from 730, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 7:
The number 75 fits into 550 7 times, leaving a remainder of 25.
The next digit of our result is 7. 
Result so far: 8959.7
If we subtract 525 from 550, we 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.

Going ahead to step 8:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 8959.73
Subtracting 225 from 250 leaves us 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.

Let's proceed to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 8959.733
Subtract 225 from 250 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.

The final result is 8959.733 with a remainder of 0.0025.
