Let's divide 75087832 by 399
Our goal is to divide 75087832 by 399.

Advancing to step 1:
399 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 399

Advancing to step 2:
When dividing 75 by 399, we get 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Take the next digit (0) from the dividend and append it to 75, then repeat: 750 / 399

Going ahead to step 3:
750 divided by 399 is 1 with a remainder of 351.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 399 from 750 leaves us with 351.
Include the next digit (8) from the dividend after 351, then repeat: 3518 / 399

Going ahead to step 4:
399 goes into 3518 8 times with a remainder of 326.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 3192 away from 3518, we end up with 326.
Bring next digit (7) of the dividend behind the 326 and repeat the process: 3267 / 399

Step 5:
3267 divided by 399 is 8 with a remainder of 75.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
Subtract 3192 from 3267 to get 75.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 399

Step 6:
399 goes into 758 1 times with a remainder of 359.
Record the quotient 1 as the next digit in the result. 
Result so far: 1881.0
The remainder is 359 after subtracting 399 from 758.
Fetch the next digit (3) from the dividend, attach it to 359 and continue: 3593 / 399

Advancing to step 7:
When dividing 3593 by 399, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 18819.0
Subtract 3591 from 3593 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 399

Moving on to step 8:
399 can be fit into 22 0 times, resulting in a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 188190.0
If we subtract 0 from 22, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
If we divide 220 by 399, we get 0 and a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 188190.0
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 10:
399 can be fit into 2200 5 times, resulting in a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 188190.05
Deduct 1995 from 2200 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 11:
2050 divided by 399 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 188190.055
If we take 1995 away from 2050, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 188190.055 with a remaining 0.0055.
