398963 divided by 75 
We want to divide 398963 by 75.

Moving on to step 1:
The number 75 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 75

Advancing to step 2:
If we divide 39 by 75, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 75

Moving on to step 3:
398 divided by 75 is 5 with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 375 from 398 to get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 75

Going ahead to step 4:
The number 75 fits into 239 3 times, leaving a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Deduct 225 from 239 and we're left with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 75

Moving on to step 5:
75 goes into 146 1 times with a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 531.0
Deduct 75 from 146 and we're left with 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 75

Advancing to step 6:
75 goes into 713 9 times with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 5319.0
Subtracting 675 from 713 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
If we divide 380 by 75, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 5319.5
If we take 375 away from 380, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
50 divided by 75 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 5319.5
Subtracting 0 from 50 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.

Advancing to step 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
The next digit of our result is 6. 
Result so far: 5319.506
If we subtract 450 from 500, we 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.

Going ahead to step 10:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 5319.5066
If we subtract 450 from 500, we 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.

Our division results in 5319.5066 with a remaining 0.0005.
