978264 ÷ 78 
Our goal is to divide 978264 by 78.

Step 1:
78 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 78

Moving on to step 2:
The number 78 fits into 97 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 19 after subtracting 78 from 97.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 78

Let's proceed to step 3:
The number 78 fits into 198 2 times, leaving 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.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 78

Going ahead to step 4:
422 divided by 78 is 5 with a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Subtract 390 from 422 to get 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 78

Going ahead to step 5:
If we divide 326 by 78, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 1254.0
The remainder is 14 after subtracting 312 from 326.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 78

Let's proceed to step 6:
If we divide 144 by 78, we get 1 and a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 12541.0
Subtract 78 from 144 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
78 goes into 660 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 12541.8
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
360 divided by 78 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 12541.84
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 12541.846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
120 divided by 78 is 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 12541.8461
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 12541.84615
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
When dividing 300 by 78, we get 3 with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 12541.846153
The remainder is 66 after subtracting 234 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 13:
When dividing 660 by 78, we get 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 12541.8461538
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
When dividing 360 by 78, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 12541.84615384
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 12541.84615384 with a remainder of 4.8e-08.
