39345 divided by 78 
We want to divide 39345 by 78.

Step 1:
3 divided by 78 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 78

On to step 2:
If we divide 39 by 78, we get 0 and 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.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 78

Going ahead to step 3:
When dividing 393 by 78, we get 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 390 from 393 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 78

Moving on to step 4:
The number 78 fits into 34 0 times, leaving a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 78

Let's proceed to step 5:
345 divided by 78 is 4 with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 504.0
The remainder is 33 after subtracting 312 from 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 6:
If we divide 330 by 78, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 504.4
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
78 goes into 180 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 504.42
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
If we divide 240 by 78, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 504.423
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
When dividing 60 by 78, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 504.423
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
78 goes into 600 7 times with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 504.42307
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
540 divided by 78 is 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 504.423076
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
If we divide 720 by 78, we get 9 and a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 504.4230769
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
180 divided by 78 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 504.42307692
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 504.42307692, and the remainder is 2.4e-08.
