We're dividing 124312 by 78 
Our goal is to divide 124312 by 78.

On to step 1:
78 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 78

Going ahead to step 2:
The number 78 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 78

Let's proceed to step 3:
78 can be fit into 124 1 times, resulting in a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 78 from 124 to get 46.
Grab the next digit (3) from the dividend, add it to 46, then carry on: 463 / 78

Step 4:
78 can be fit into 463 5 times, resulting in a remainder of 73.
The next digit of our result is 5. 
Result so far: 15.0
If we take 390 away from 463, we end up with 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 78

Advancing to step 5:
The number 78 fits into 731 9 times, leaving a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
Deduct 702 from 731 and we're left with 29.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 78

Step 6:
78 can be fit into 292 3 times, resulting in a remainder of 58.
The next digit of our result is 3. 
Result so far: 1593.0
The remainder is 58 after subtracting 234 from 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
When dividing 580 by 78, we get 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 1593.7
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
340 divided by 78 is 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 1593.74
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.

Advancing to step 9:
78 goes into 280 3 times with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 1593.743
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.

Going ahead to step 10:
When dividing 460 by 78, we get 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 1593.7435
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
78 can be fit into 700 8 times, resulting in a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 1593.74358
If we take 624 away from 700, we end up 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.

Going ahead to step 12:
760 divided by 78 is 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 1593.743589
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
78 goes into 580 7 times with a remainder of 34.
The next digit of our result is 7. 
Result so far: 1593.7435897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
The number 78 fits into 340 4 times, leaving a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 1593.74358974
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 1593.74358974 with a balance of 2.8e-08.
