Let's divide 979312 by 78
Our goal is to divide 979312 by 78.

Let's proceed to step 1:
When dividing 9 by 78, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
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

Let's proceed to step 2:
When dividing 97 by 78, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 78 from 97 leaves us with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 78

Going ahead to step 3:
199 divided by 78 is 2 with a remainder of 43.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 156 from 199 to get 43.
Grab the next digit (3) from the dividend, add it to 43, then carry on: 433 / 78

Going ahead to step 4:
When dividing 433 by 78, we get 5 with a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtract 390 from 433 to get 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 78

Step 5:
If we divide 431 by 78, we get 5 and a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 1255.0
The remainder is 41 after subtracting 390 from 431.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 78

Going ahead to step 6:
412 divided by 78 is 5 with a remainder of 22.
The next digit of our result is 5. 
Result so far: 12555.0
Subtract 390 from 412 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
78 goes into 220 2 times with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 12555.2
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 8:
If we divide 640 by 78, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 12555.28
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 78, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 12555.282
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
78 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 12555.282
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
If we divide 400 by 78, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 12555.28205
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
The number 78 fits into 100 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 12555.282051
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
If we divide 220 by 78, we get 2 and a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 12555.2820512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 12555.28205128
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 12555.28205128, with a leftover of 1.6e-08.
