We divide 869407 by 75
We want to figure out the number of times 869407 can be divided by 75.

On to step 1:
If we divide 8 by 75, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 75

Going ahead to step 2:
75 can be fit into 86 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 75 from 86 leaves us with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 75

Moving on to step 3:
75 can be fit into 119 1 times, resulting in a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 75 from 119 leaves us with 44.
Bring next digit (4) of the dividend behind the 44 and repeat the process: 444 / 75

Let's proceed to step 4:
If we divide 444 by 75, we get 5 and a remainder of 69.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
The remainder is 69 after subtracting 375 from 444.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 75

Moving on to step 5:
75 goes into 690 9 times with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 1159.0
If we subtract 675 from 690, we get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 75

Let's proceed to step 6:
When dividing 157 by 75, we get 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 11592.0
Subtracting 150 from 157 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
When dividing 70 by 75, we get 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 11592.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
If we divide 700 by 75, we get 9 and a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 11592.09
Subtract 675 from 700 to 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.

Let's proceed to step 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 11592.093
Subtract 225 from 250 to 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.

Moving on to step 10:
75 goes into 250 3 times with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 11592.0933
If we take 225 away from 250, 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.

The final outcome is 11592.0933, with a leftover of 0.00025.
