Let's divide 78344956 by 639
We want to divide 78344956 by 639.

Let's proceed to step 1:
639 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 639

Advancing to step 2:
The number 639 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 639

Advancing to step 3:
783 divided by 639 is 1 with a remainder of 144.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 639 from 783 to get 144.
Append the next digit (4) from the dividend to 144 and continue with: 1444 / 639

On to step 4:
639 can be fit into 1444 2 times, resulting in a remainder of 166.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 166 after subtracting 1278 from 1444.
Append the next digit (4) from the dividend to 166 and continue with: 1664 / 639

Let's proceed to step 5:
When dividing 1664 by 639, we get 2 with a remainder of 386.
The next digit of our result is 2. 
Result so far: 122.0
If we take 1278 away from 1664, we end up with 386.
Append the next digit (9) from the dividend to 386 and continue with: 3869 / 639

Step 6:
When dividing 3869 by 639, we get 6 with a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 1226.0
If we subtract 3834 from 3869, we get 35.
Take the next digit (5) from the dividend and append it to 35, then repeat: 355 / 639

Moving on to step 7:
If we divide 355 by 639, we get 0 and a remainder of 355.
Record the quotient 0 as the next digit in the result. 
Result so far: 12260.0
If we subtract 0 from 355, we get 355.
Include the next digit (6) from the dividend after 355, then repeat: 3556 / 639

Moving on to step 8:
When dividing 3556 by 639, we get 5 with a remainder of 361.
The next digit of our result is 5. 
Result so far: 122605.0
The remainder is 361 after subtracting 3195 from 3556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 9:
The number 639 fits into 3610 5 times, leaving a remainder of 415.
Write down 5 as next digit of the result. 
Result so far: 122605.5
If we take 3195 away from 3610, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 10:
639 can be fit into 4150 6 times, resulting in a remainder of 316.
The number 6 becomes the next digit in our result. 
Result so far: 122605.56
Subtracting 3834 from 4150 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 11:
639 goes into 3160 4 times with a remainder of 604.
Put 4 as the next digit of the answer. 
Result so far: 122605.564
If we subtract 2556 from 3160, we get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Advancing to step 12:
639 can be fit into 6040 9 times, resulting in a remainder of 289.
The next digit of our result is 9. 
Result so far: 122605.5649
The remainder is 289 after subtracting 5751 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Advancing to step 13:
The number 639 fits into 2890 4 times, leaving a remainder of 334.
The number 4 becomes the next digit in our result. 
Result so far: 122605.56494
Subtract 2556 from 2890 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 14:
639 goes into 3340 5 times with a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 122605.564945
If we subtract 3195 from 3340, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 15:
If we divide 1450 by 639, we get 2 and a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 122605.5649452
Subtracting 1278 from 1450 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 16:
1720 divided by 639 is 2 with a remainder of 442.
The number 2 becomes the next digit in our result. 
Result so far: 122605.56494522
The remainder is 442 after subtracting 1278 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

The quotient of the division is 122605.56494522, and the remainder is 4.42e-07.
