398175 divided by 2 
Let's see how many times 2 fits into 398175.

On to step 1:
The number 2 fits into 3 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 1 after subtracting 2 from 3.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Let's proceed to step 2:
2 goes into 19 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 18 from 19 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

On to step 3:
When dividing 18 by 2, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
If we subtract 18 from 18, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Moving on to step 4:
When dividing 1 by 2, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 1990.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

Advancing to step 5:
2 can be fit into 17 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 19908.0
If we subtract 16 from 17, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Going ahead to step 6:
When dividing 15 by 2, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 199087.0
The remainder is 1 after subtracting 14 from 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 199087.5
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 199087.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 199087.5
Subtract 0 from 0 to get 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 199087.5 with a remainder of 0.0.
