63671006 divided by 639 
We want to figure out the number of times 63671006 can be divided by 639.

Going ahead to step 1:
639 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
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 639

Moving on to step 2:
63 divided by 639 is 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 639

Going ahead to step 3:
When dividing 636 by 639, we get 0 with a remainder of 636.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 636 leaves us with 636.
Take the next digit (7) from the dividend and append it to 636, then repeat: 6367 / 639

Let's proceed to step 4:
If we divide 6367 by 639, we get 9 and a remainder of 616.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 616 after subtracting 5751 from 6367.
Include the next digit (1) from the dividend after 616, then repeat: 6161 / 639

Moving on to step 5:
639 goes into 6161 9 times with a remainder of 410.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we subtract 5751 from 6161, we get 410.
Append the next digit (0) from the dividend to 410 and continue with: 4100 / 639

Let's proceed to step 6:
When dividing 4100 by 639, we get 6 with a remainder of 266.
Use 6 as the next digit of our solution. 
Result so far: 996.0
Deduct 3834 from 4100 and we're left with 266.
Take the next digit (0) from the dividend and append it to 266, then repeat: 2660 / 639

Moving on to step 7:
If we divide 2660 by 639, we get 4 and a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 9964.0
The remainder is 104 after subtracting 2556 from 2660.
Take the next digit (6) from the dividend and append it to 104, then repeat: 1046 / 639

Going ahead to step 8:
639 can be fit into 1046 1 times, resulting in a remainder of 407.
Put 1 as the next digit of the answer. 
Result so far: 99641.0
Deduct 639 from 1046 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Moving on to step 9:
When dividing 4070 by 639, we get 6 with a remainder of 236.
The next digit of our result is 6. 
Result so far: 99641.6
The remainder is 236 after subtracting 3834 from 4070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 10:
639 goes into 2360 3 times with a remainder of 443.
The number 3 becomes the next digit in our result. 
Result so far: 99641.63
Subtracting 1917 from 2360 leaves us with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Going ahead to step 11:
The number 639 fits into 4430 6 times, leaving a remainder of 596.
The number 6 becomes the next digit in our result. 
Result so far: 99641.636
Subtracting 3834 from 4430 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 12:
If we divide 5960 by 639, we get 9 and a remainder of 209.
The next digit of our result is 9. 
Result so far: 99641.6369
Deduct 5751 from 5960 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 13:
When dividing 2090 by 639, we get 3 with a remainder of 173.
Write down 3 as next digit of the result. 
Result so far: 99641.63693
Deduct 1917 from 2090 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 14:
When dividing 1730 by 639, we get 2 with a remainder of 452.
The next digit of our result is 2. 
Result so far: 99641.636932
Deduct 1278 from 1730 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 15:
639 can be fit into 4520 7 times, resulting in a remainder of 47.
The next digit of our result is 7. 
Result so far: 99641.6369327
Subtract 4473 from 4520 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 16:
When dividing 470 by 639, we get 0 with a remainder of 470.
The number 0 becomes the next digit in our result. 
Result so far: 99641.6369327
Deduct 0 from 470 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

After the division, we end up with 99641.6369327 and a remainder of 4.7e-07.
