We divide 360990 by 75
We're looking to find how many times 75 goes into 360990.

Let's proceed to step 1:
When dividing 3 by 75, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 75

Step 2:
75 can be fit into 36 0 times, resulting in a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 75

On to step 3:
When dividing 360 by 75, we get 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 300 from 360 to get 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 75

Moving on to step 4:
609 divided by 75 is 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we take 600 away from 609, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 75

Step 5:
75 can be fit into 99 1 times, resulting in a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 481.0
The remainder is 24 after subtracting 75 from 99.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 75

Step 6:
240 divided by 75 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 4813.0
Subtract 225 from 240 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
The number 75 fits into 150 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 4813.2
Deduct 150 from 150 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4813.2
If we subtract 0 from 0, 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.

Advancing to step 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4813.2
Subtract 0 from 0 to 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.

The final outcome is 4813.2, with a leftover of 0.0.
