We look at the division of 591366 by 75 
We're looking to find how many times 75 goes into 591366.

Step 1:
When dividing 5 by 75, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 75

Let's proceed to step 2:
75 can be fit into 59 0 times, resulting in a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 59 leaves us with 59.
Bring next digit (1) of the dividend behind the 59 and repeat the process: 591 / 75

On to step 3:
75 goes into 591 7 times with a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 525 from 591, we get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 75

Moving on to step 4:
When dividing 663 by 75, we get 8 with a remainder of 63.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtract 600 from 663 to get 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 75

Step 5:
75 goes into 636 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 788.0
If we take 600 away from 636, we end up with 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 75

Step 6:
75 goes into 366 4 times with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 7884.0
If we subtract 300 from 366, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 7:
If we divide 660 by 75, we get 8 and a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 7884.8
Subtracting 600 from 660 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
75 goes into 600 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 7884.88
If we subtract 600 from 600, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 7884.88 with a remaining 0.0.
