We're dividing 878653 by 75 
We're looking to find how many times 75 goes into 878653.

Going ahead to step 1:
75 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 75

Going ahead to step 2:
75 goes into 87 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 75 from 87, we get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 75

On to step 3:
When dividing 128 by 75, we get 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 75 from 128, we get 53.
Take the next digit (6) from the dividend and append it to 53, then repeat: 536 / 75

Moving on to step 4:
The number 75 fits into 536 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 117.0
Deduct 525 from 536 and we're left with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 75

Going ahead to step 5:
The number 75 fits into 115 1 times, leaving a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1171.0
The remainder is 40 after subtracting 75 from 115.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 75

Advancing to step 6:
When dividing 403 by 75, we get 5 with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 11715.0
Subtract 375 from 403 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
280 divided by 75 is 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 11715.3
Subtract 225 from 280 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 8:
When dividing 550 by 75, we get 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 11715.37
Deduct 525 from 550 and we're left 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.

Advancing to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 11715.373
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.

Advancing to step 10:
250 divided by 75 is 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 11715.3733
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.

Our division results in 11715.3733 with a remaining 0.00025.
