We're dividing 840909 by 75 
Let's see how many times 75 fits into 840909.

On to step 1:
When dividing 8 by 75, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 75

Let's proceed to step 2:
The number 75 fits into 84 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 9 after subtracting 75 from 84.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 75

Moving on to step 3:
If we divide 90 by 75, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 75 from 90 to get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 75

Step 4:
When dividing 159 by 75, we get 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtracting 150 from 159 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 75

Advancing to step 5:
The number 75 fits into 90 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1121.0
If we subtract 75 from 90, we get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 75

Moving on to step 6:
75 goes into 159 2 times with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 11212.0
If we subtract 150 from 159, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
75 goes into 90 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 11212.1
If we subtract 75 from 90, we 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.

Step 8:
75 goes into 150 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 11212.12
If we take 150 away from 150, we end up 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.

Moving on to step 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11212.12
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11212.12
The remainder is 0 after subtracting 0 from 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 result is 11212.12 with a remainder of 0.0.
