663964 ÷ 75 
Our goal is to divide 663964 by 75.

Advancing to step 1:
75 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 75

On to step 2:
75 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 75

Step 3:
If we divide 663 by 75, we get 8 and a remainder of 63.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 600 from 663 and we're left with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 75

Step 4:
639 divided by 75 is 8 with a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 88.0
The remainder is 39 after subtracting 600 from 639.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 75

Step 5:
396 divided by 75 is 5 with a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 885.0
Deduct 375 from 396 and we're left with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 75

Moving on to step 6:
When dividing 214 by 75, we get 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 8852.0
Subtracting 150 from 214 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 7:
75 goes into 640 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 8852.8
If we take 600 away from 640, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
When dividing 400 by 75, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 8852.85
Subtracting 375 from 400 leaves us 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:
250 divided by 75 is 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 8852.853
Deduct 225 from 250 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.

Step 10:
If we divide 250 by 75, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 8852.8533
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.

In conclusion, the division gives 8852.8533 with a balance of 0.00025.
