We look at the division of 65379134 by 639 
Our goal is to divide 65379134 by 639.

Step 1:
6 divided by 639 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 639

Going ahead to step 2:
639 goes into 65 0 times with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 639

Going ahead to step 3:
639 can be fit into 653 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 639 from 653 to get 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 639

On to step 4:
If we divide 147 by 639, we get 0 and a remainder of 147.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 147, we end up with 147.
Include the next digit (9) from the dividend after 147, then repeat: 1479 / 639

Going ahead to step 5:
If we divide 1479 by 639, we get 2 and a remainder of 201.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 201 after subtracting 1278 from 1479.
Fetch the next digit (1) from the dividend, attach it to 201 and continue: 2011 / 639

Going ahead to step 6:
When dividing 2011 by 639, we get 3 with a remainder of 94.
The next digit of our result is 3. 
Result so far: 1023.0
Subtracting 1917 from 2011 leaves us with 94.
Bring next digit (3) of the dividend behind the 94 and repeat the process: 943 / 639

Advancing to step 7:
943 divided by 639 is 1 with a remainder of 304.
Record the quotient 1 as the next digit in the result. 
Result so far: 10231.0
Deduct 639 from 943 and we're left with 304.
Take the next digit (4) from the dividend and append it to 304, then repeat: 3044 / 639

Going ahead to step 8:
When dividing 3044 by 639, we get 4 with a remainder of 488.
Use 4 as the next digit of our solution. 
Result so far: 102314.0
The remainder is 488 after subtracting 2556 from 3044.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 9:
4880 divided by 639 is 7 with a remainder of 407.
Record the quotient 7 as the next digit in the result. 
Result so far: 102314.7
The remainder is 407 after subtracting 4473 from 4880.
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 10:
639 can be fit into 4070 6 times, resulting in a remainder of 236.
The number 6 becomes the next digit in our result. 
Result so far: 102314.76
Subtract 3834 from 4070 to get 236.
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 11:
639 can be fit into 2360 3 times, resulting in a remainder of 443.
Record the quotient 3 as the next digit in the result. 
Result so far: 102314.763
Subtract 1917 from 2360 to get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Advancing to step 12:
639 goes into 4430 6 times with a remainder of 596.
Record the quotient 6 as the next digit in the result. 
Result so far: 102314.7636
Deduct 3834 from 4430 and we're left 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.

On to step 13:
5960 divided by 639 is 9 with a remainder of 209.
Put 9 as the next digit of the answer. 
Result so far: 102314.76369
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.

Advancing to step 14:
639 goes into 2090 3 times with a remainder of 173.
Record the quotient 3 as the next digit in the result. 
Result so far: 102314.763693
Subtract 1917 from 2090 to get 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 15:
639 goes into 1730 2 times with a remainder of 452.
The next digit of our result is 2. 
Result so far: 102314.7636932
If we take 1278 away from 1730, we end up 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.

Advancing to step 16:
If we divide 4520 by 639, we get 7 and a remainder of 47.
The next digit of our result is 7. 
Result so far: 102314.76369327
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.

Our division results in 102314.76369327 with a remaining 4.7e-08.
