We're dividing 336910 by 78 
We want to divide 336910 by 78.

Going ahead to step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 78

Let's proceed to step 2:
33 divided by 78 is 0 with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 78

Moving on to step 3:
If we divide 336 by 78, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 312 from 336, we get 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 78

Step 4:
When dividing 249 by 78, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 234 away from 249, we end up with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 78

Going ahead to step 5:
If we divide 151 by 78, we get 1 and a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 431.0
Deduct 78 from 151 and we're left with 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 78

Step 6:
When dividing 730 by 78, we get 9 with a remainder of 28.
The next digit of our result is 9. 
Result so far: 4319.0
The remainder is 28 after subtracting 702 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
When dividing 280 by 78, we get 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 4319.3
The remainder is 46 after subtracting 234 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
If we divide 460 by 78, we get 5 and a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 4319.35
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
78 goes into 700 8 times with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 4319.358
Subtracting 624 from 700 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
If we divide 760 by 78, we get 9 and a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 4319.3589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
When dividing 580 by 78, we get 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 4319.35897
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
The number 78 fits into 340 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 4319.358974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
78 goes into 280 3 times with a remainder of 46.
The next digit of our result is 3. 
Result so far: 4319.3589743
Subtracting 234 from 280 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 14:
The number 78 fits into 460 5 times, leaving a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 4319.35897435
If we subtract 390 from 460, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 4319.35897435 with a remaining 7e-08.
