We're dividing 78336387 by 439 
We want to figure out the number of times 78336387 can be divided by 439.

Step 1:
If we divide 7 by 439, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 439

Advancing to step 2:
If we divide 78 by 439, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 439

Moving on to step 3:
439 goes into 783 1 times with a remainder of 344.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 439 from 783 and we're left with 344.
Append the next digit (3) from the dividend to 344 and continue with: 3443 / 439

Going ahead to step 4:
The number 439 fits into 3443 7 times, leaving a remainder of 370.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 370 after subtracting 3073 from 3443.
Append the next digit (6) from the dividend to 370 and continue with: 3706 / 439

Step 5:
If we divide 3706 by 439, we get 8 and a remainder of 194.
Write down 8 as next digit of the result. 
Result so far: 178.0
Subtracting 3512 from 3706 leaves us with 194.
Append the next digit (3) from the dividend to 194 and continue with: 1943 / 439

Going ahead to step 6:
If we divide 1943 by 439, we get 4 and a remainder of 187.
Use 4 as the next digit of our solution. 
Result so far: 1784.0
Deduct 1756 from 1943 and we're left with 187.
Grab the next digit (8) from the dividend, add it to 187, then carry on: 1878 / 439

Advancing to step 7:
If we divide 1878 by 439, we get 4 and a remainder of 122.
The next digit of our result is 4. 
Result so far: 17844.0
Subtracting 1756 from 1878 leaves us with 122.
Fetch the next digit (7) from the dividend, attach it to 122 and continue: 1227 / 439

Let's proceed to step 8:
The number 439 fits into 1227 2 times, leaving a remainder of 349.
The number 2 becomes the next digit in our result. 
Result so far: 178442.0
If we take 878 away from 1227, we end up with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Let's proceed to step 9:
The number 439 fits into 3490 7 times, leaving a remainder of 417.
Use 7 as the next digit of our solution. 
Result so far: 178442.7
Deduct 3073 from 3490 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Moving on to step 10:
439 can be fit into 4170 9 times, resulting in a remainder of 219.
Record the quotient 9 as the next digit in the result. 
Result so far: 178442.79
If we take 3951 away from 4170, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Advancing to step 11:
439 goes into 2190 4 times with a remainder of 434.
Write down 4 as next digit of the result. 
Result so far: 178442.794
Subtract 1756 from 2190 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 12:
When dividing 4340 by 439, we get 9 with a remainder of 389.
Put 9 as the next digit of the answer. 
Result so far: 178442.7949
Subtract 3951 from 4340 to get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 13:
3890 divided by 439 is 8 with a remainder of 378.
The next digit of our result is 8. 
Result so far: 178442.79498
Subtract 3512 from 3890 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 14:
439 can be fit into 3780 8 times, resulting in a remainder of 268.
Record the quotient 8 as the next digit in the result. 
Result so far: 178442.794988
If we take 3512 away from 3780, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

In conclusion, the division gives 178442.794988 with a balance of 2.68e-05.
