Let's divide 68478877 by 639
Let's see how many times 639 fits into 68478877.

Let's proceed to step 1:
6 divided by 639 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 639

Let's proceed to step 2:
639 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 639

Advancing to step 3:
639 can be fit into 684 1 times, resulting in a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 639 from 684 and we're left with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 639

Going ahead to step 4:
639 goes into 457 0 times with a remainder of 457.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 457 after subtracting 0 from 457.
Fetch the next digit (8) from the dividend, attach it to 457 and continue: 4578 / 639

Going ahead to step 5:
4578 divided by 639 is 7 with a remainder of 105.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Deduct 4473 from 4578 and we're left with 105.
Include the next digit (8) from the dividend after 105, then repeat: 1058 / 639

Step 6:
The number 639 fits into 1058 1 times, leaving a remainder of 419.
Put 1 as the next digit of the answer. 
Result so far: 1071.0
Subtracting 639 from 1058 leaves us with 419.
Bring next digit (7) of the dividend behind the 419 and repeat the process: 4197 / 639

Advancing to step 7:
The number 639 fits into 4197 6 times, leaving a remainder of 363.
Write down 6 as next digit of the result. 
Result so far: 10716.0
Subtract 3834 from 4197 to get 363.
Bring next digit (7) of the dividend behind the 363 and repeat the process: 3637 / 639

Moving on to step 8:
If we divide 3637 by 639, we get 5 and a remainder of 442.
Put 5 as the next digit of the answer. 
Result so far: 107165.0
If we subtract 3195 from 3637, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 9:
If we divide 4420 by 639, we get 6 and a remainder of 586.
Write down 6 as next digit of the result. 
Result so far: 107165.6
Subtracting 3834 from 4420 leaves us with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Advancing to step 10:
If we divide 5860 by 639, we get 9 and a remainder of 109.
Put 9 as the next digit of the answer. 
Result so far: 107165.69
Subtract 5751 from 5860 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 11:
639 can be fit into 1090 1 times, resulting in a remainder of 451.
Use 1 as the next digit of our solution. 
Result so far: 107165.691
Deduct 639 from 1090 and we're left with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Going ahead to step 12:
639 goes into 4510 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 107165.6917
If we subtract 4473 from 4510, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 13:
When dividing 370 by 639, we get 0 with a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 107165.6917
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 14:
639 can be fit into 3700 5 times, resulting in a remainder of 505.
The next digit of our result is 5. 
Result so far: 107165.691705
Deduct 3195 from 3700 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Advancing to step 15:
5050 divided by 639 is 7 with a remainder of 577.
Write down 7 as next digit of the result. 
Result so far: 107165.6917057
Subtract 4473 from 5050 to get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Going ahead to step 16:
639 goes into 5770 9 times with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 107165.69170579
If we take 5751 away from 5770, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 107165.69170579 with a remainder of 1.9e-08.
