We divide 342394 by 78
Our goal is to divide 342394 by 78.

Going ahead to step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 78

On to step 2:
78 goes into 34 0 times with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 78

Step 3:
The number 78 fits into 342 4 times, leaving a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 312 from 342 and we're left with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 78

Advancing to step 4:
The number 78 fits into 303 3 times, leaving a remainder of 69.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 234 from 303, we get 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 78

Moving on to step 5:
78 goes into 699 8 times with a remainder of 75.
Put 8 as the next digit of the answer. 
Result so far: 438.0
If we subtract 624 from 699, we get 75.
Grab the next digit (4) from the dividend, add it to 75, then carry on: 754 / 78

On to step 6:
78 goes into 754 9 times with a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 4389.0
If we take 702 away from 754, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
When dividing 520 by 78, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 4389.6
Subtract 468 from 520 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
78 goes into 520 6 times with a remainder of 52.
The next digit of our result is 6. 
Result so far: 4389.66
If we subtract 468 from 520, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 4389.66 with a balance of 0.052.
