We divide 339310 by 78
We want to figure out the number of times 339310 can be divided by 78.

Step 1:
The number 78 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 78

Moving on to step 2:
78 can be fit into 33 0 times, resulting in a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 78

Going ahead to step 3:
The number 78 fits into 339 4 times, leaving a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 312 from 339 leaves us with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 78

Step 4:
If we divide 273 by 78, we get 3 and a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 234 from 273 leaves us with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 78

On to step 5:
78 goes into 391 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 435.0
If we take 390 away from 391, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 78

On to step 6:
10 divided by 78 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 4350.0
Deduct 0 from 10 and we're left 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.

Step 7:
78 goes into 100 1 times with a remainder of 22.
The next digit of our result is 1. 
Result so far: 4350.1
Subtract 78 from 100 to 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.

On to step 8:
220 divided by 78 is 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 4350.12
If we subtract 156 from 220, we 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.

Moving on to step 9:
If we divide 640 by 78, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 4350.128
Deduct 624 from 640 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
78 goes into 160 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 4350.1282
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
78 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 4350.1282
If we take 0 away from 40, we end up 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.

On to step 12:
78 goes into 400 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 4350.128205
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
100 divided by 78 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 4350.1282051
Subtracting 78 from 100 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 14:
When dividing 220 by 78, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 4350.12820512
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 4350.12820512 with a balance of 6.4e-08.
