We look at the division of 639332 by 74 
We want to figure out the number of times 639332 can be divided by 74.

On to step 1:
74 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 74

On to step 2:
74 can be fit into 63 0 times, resulting in a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 74

Let's proceed to step 3:
639 divided by 74 is 8 with a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 592 away from 639, we end up with 47.
Append the next digit (3) from the dividend to 47 and continue with: 473 / 74

Step 4:
473 divided by 74 is 6 with a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtract 444 from 473 to get 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 74

Step 5:
The number 74 fits into 293 3 times, leaving a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 863.0
If we subtract 222 from 293, we get 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 74

On to step 6:
74 goes into 712 9 times with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 8639.0
If we take 666 away from 712, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
460 divided by 74 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 8639.6
The remainder is 16 after subtracting 444 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
160 divided by 74 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 8639.62
Deduct 148 from 160 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
If we divide 120 by 74, we get 1 and a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 8639.621
The remainder is 46 after subtracting 74 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
460 divided by 74 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 8639.6216
Subtracting 444 from 460 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
160 divided by 74 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 8639.62162
The remainder is 12 after subtracting 148 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
The number 74 fits into 120 1 times, leaving a remainder of 46.
The next digit of our result is 1. 
Result so far: 8639.621621
Deduct 74 from 120 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
74 can be fit into 460 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 8639.6216216
Subtract 444 from 460 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
When dividing 160 by 74, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 8639.62162162
If we take 148 away from 160, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 8639.62162162 with a remaining 1.2e-08.
