639330 ÷ 75 
We're looking to find how many times 75 goes into 639330.

On to step 1:
If we divide 6 by 75, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 75

Let's proceed to step 2:
If we divide 63 by 75, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 75

Advancing to step 3:
639 divided by 75 is 8 with a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 600 from 639 and we're left with 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 75

Going ahead to step 4:
If we divide 393 by 75, we get 5 and a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtract 375 from 393 to get 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 75

Step 5:
If we divide 183 by 75, we get 2 and a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 852.0
Deduct 150 from 183 and we're left with 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 75

Going ahead to step 6:
If we divide 330 by 75, we get 4 and a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 8524.0
The remainder is 30 after subtracting 300 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
75 can be fit into 300 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 8524.4
Deduct 300 from 300 and we're left 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.

Advancing to step 8:
0 divided by 75 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8524.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8524.4
Deduct 0 from 0 and we're left 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.

After the division, we end up with 8524.4 and a remainder of 0.0.
