We're dividing 978369 by 78 
We want to divide 978369 by 78.

Step 1:
The number 78 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 78

On to step 2:
78 goes into 97 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 78 from 97 leaves us with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 78

Let's proceed to step 3:
If we divide 198 by 78, we get 2 and a remainder of 42.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 156 from 198 and we're left with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 78

On to step 4:
423 divided by 78 is 5 with a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 125.0
If we subtract 390 from 423, we get 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 78

Advancing to step 5:
78 goes into 336 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 1254.0
Subtract 312 from 336 to get 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 78

On to step 6:
78 can be fit into 249 3 times, resulting in a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 12543.0
The remainder is 15 after subtracting 234 from 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
When dividing 150 by 78, we get 1 with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 12543.1
Deduct 78 from 150 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 8:
If we divide 720 by 78, we get 9 and a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 12543.19
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
180 divided by 78 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12543.192
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
If we divide 240 by 78, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 12543.1923
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
If we divide 60 by 78, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 12543.1923
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
600 divided by 78 is 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 12543.192307
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 13:
78 can be fit into 540 6 times, resulting in a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 12543.1923076
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
78 goes into 720 9 times with a remainder of 18.
The next digit of our result is 9. 
Result so far: 12543.19230769
Subtracting 702 from 720 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 12543.19230769 with a remainder of 1.8e-08.
