We divide 870239 by 75
Let's see how many times 75 fits into 870239.

Moving on to step 1:
If we divide 8 by 75, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 75

Moving on to step 2:
75 can be fit into 87 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 75 from 87 and we're left with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 75

Advancing to step 3:
120 divided by 75 is 1 with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 75 from 120 leaves us with 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 75

Step 4:
75 goes into 452 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 116.0
If we subtract 450 from 452, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 75

On to step 5:
The number 75 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 1160.0
If we subtract 0 from 23, we get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 75

On to step 6:
75 goes into 239 3 times with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 11603.0
If we subtract 225 from 239, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
140 divided by 75 is 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 11603.1
Subtract 75 from 140 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 8:
When dividing 650 by 75, we get 8 with a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 11603.18
If we subtract 600 from 650, we 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.

Step 9:
500 divided by 75 is 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 11603.186
If we take 450 away from 500, we end up 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.

On to step 10:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 11603.1866
Deduct 450 from 500 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.

The final result is 11603.1866 with a remainder of 0.0005.
