869104 ÷ 75 
Our goal is to divide 869104 by 75.

Advancing to step 1:
8 divided by 75 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 75

Moving on to step 2:
If we divide 86 by 75, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 75 away from 86, we end up with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 75

Going ahead to step 3:
119 divided by 75 is 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 75 from 119 leaves us with 44.
Include the next digit (1) from the dividend after 44, then repeat: 441 / 75

Moving on to step 4:
If we divide 441 by 75, we get 5 and a remainder of 66.
The next digit of our result is 5. 
Result so far: 115.0
Subtract 375 from 441 to get 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 75

Going ahead to step 5:
When dividing 660 by 75, we get 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 1158.0
Subtracting 600 from 660 leaves us with 60.
Append the next digit (4) from the dividend to 60 and continue with: 604 / 75

On to step 6:
75 can be fit into 604 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 11588.0
Subtract 600 from 604 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
The number 75 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 11588.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
75 goes into 400 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 11588.05
If we take 375 away from 400, we end up 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:
If we divide 250 by 75, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 11588.053
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.

Moving on to step 10:
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: 11588.0533
If we subtract 225 from 250, 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.

After the division, we end up with 11588.0533 and a remainder of 0.00025.
