639381 ÷ 75 
Let's see how many times 75 fits into 639381.

Advancing to step 1:
75 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 75

Advancing to step 2:
75 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 75

Step 3:
639 divided by 75 is 8 with a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 39 after subtracting 600 from 639.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 75

Moving on to step 4:
75 can be fit into 393 5 times, resulting in a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we subtract 375 from 393, we get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 75

Let's proceed to step 5:
75 goes into 188 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 852.0
The remainder is 38 after subtracting 150 from 188.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 75

Going ahead to step 6:
The number 75 fits into 381 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 8525.0
Subtracting 375 from 381 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
If we divide 60 by 75, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 8525.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
600 divided by 75 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8525.08
The remainder is 0 after subtracting 600 from 600.
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:
0 divided by 75 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8525.08
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.

Step 10:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8525.08
If we take 0 away from 0, we end up with 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 quotient of the division is 8525.08, and the remainder is 0.0.
