382639 divided by 78 
Let's see how many times 78 fits into 382639.

Advancing to step 1:
78 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 78

Going ahead to step 2:
78 can be fit into 38 0 times, resulting in a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 78

Going ahead to step 3:
If we divide 382 by 78, we get 4 and a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 312 from 382 to get 70.
Include the next digit (6) from the dividend after 70, then repeat: 706 / 78

Going ahead to step 4:
If we divide 706 by 78, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtract 702 from 706 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 78

On to step 5:
When dividing 43 by 78, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 490.0
Subtract 0 from 43 to get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 78

Moving on to step 6:
78 can be fit into 439 5 times, resulting in a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 4905.0
Deduct 390 from 439 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
When dividing 490 by 78, we get 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 4905.6
Subtracting 468 from 490 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
78 goes into 220 2 times with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 4905.62
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 4905.628
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 4905.6282
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
40 divided by 78 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 4905.6282
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
78 goes into 400 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 4905.628205
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
100 divided by 78 is 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 4905.6282051
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
When dividing 220 by 78, we get 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 4905.62820512
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 4905.62820512 and a remainder of 6.4e-08.
