Let's divide 391955 by 78
Let's see how many times 78 fits into 391955.

Going ahead to step 1:
3 divided by 78 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 78

Step 2:
The number 78 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 78

Advancing to step 3:
The number 78 fits into 391 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 390 from 391, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 78

Step 4:
78 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 19, we get 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 78

Let's proceed to step 5:
78 goes into 195 2 times with a remainder of 39.
The next digit of our result is 2. 
Result so far: 502.0
The remainder is 39 after subtracting 156 from 195.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 78

Going ahead to step 6:
78 goes into 395 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5025.0
Deduct 390 from 395 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
If we divide 50 by 78, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 5025.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 5025.06
Subtract 468 from 500 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
78 can be fit into 320 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 5025.064
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
78 goes into 80 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 5025.0641
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
78 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 5025.0641
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
The number 78 fits into 200 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 5025.064102
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 13:
78 goes into 440 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 5025.0641025
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
500 divided by 78 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 5025.06410256
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 5025.06410256, and the remainder is 3.2e-08.
