Let's divide 639293 by 66
We're looking to find how many times 66 goes into 639293.

Moving on to step 1:
The number 66 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 66

Advancing to step 2:
66 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 66

Advancing to step 3:
66 goes into 639 9 times with a remainder of 45.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 594 from 639 and we're left with 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 66

Going ahead to step 4:
The number 66 fits into 452 6 times, leaving a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 96.0
Subtract 396 from 452 to get 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 66

Going ahead to step 5:
66 can be fit into 569 8 times, resulting in a remainder of 41.
Write down 8 as next digit of the result. 
Result so far: 968.0
Subtract 528 from 569 to get 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 66

Advancing to step 6:
413 divided by 66 is 6 with a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 9686.0
If we take 396 away from 413, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
If we divide 170 by 66, we get 2 and a remainder of 38.
The next digit of our result is 2. 
Result so far: 9686.2
If we take 132 away from 170, we end up 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.

Step 8:
When dividing 380 by 66, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 9686.25
Subtracting 330 from 380 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.

Let's proceed to step 9:
66 goes into 500 7 times with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 9686.257
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
If we divide 380 by 66, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 9686.2575
Deduct 330 from 380 and we're left 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.

Moving on to step 11:
If we divide 500 by 66, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 9686.25757
Deduct 462 from 500 and we're left 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 12:
If we divide 380 by 66, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 9686.257575
Subtracting 330 from 380 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.

Moving on to step 13:
If we divide 500 by 66, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 9686.2575757
Subtracting 462 from 500 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.

Let's proceed to step 14:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 9686.25757575
Deduct 330 from 380 and we're left 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.

Our division results in 9686.25757575 with a remaining 5e-08.
