We're dividing 863498 by 75 
We want to divide 863498 by 75.

Moving on to step 1:
The number 75 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 75

Step 2:
When dividing 86 by 75, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
If we take 75 away from 86, we end up with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 75

On to step 3:
75 can be fit into 113 1 times, resulting in a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 75 away from 113, we end up with 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 75

Going ahead to step 4:
384 divided by 75 is 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
If we subtract 375 from 384, we get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 75

Let's proceed to step 5:
75 can be fit into 99 1 times, resulting in a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1151.0
If we subtract 75 from 99, we get 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 75

On to step 6:
75 can be fit into 248 3 times, resulting in a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 11513.0
The remainder is 23 after subtracting 225 from 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
The number 75 fits into 230 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 11513.3
Subtract 225 from 230 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 75, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 11513.3
Subtract 0 from 50 to 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.

Moving on to step 9:
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: 11513.306
Subtracting 450 from 500 leaves us 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.

Step 10:
75 can be fit into 500 6 times, resulting in a remainder of 50.
The next digit of our result is 6. 
Result so far: 11513.3066
Subtracting 450 from 500 leaves us 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.

Our division results in 11513.3066 with a remaining 0.0005.
