Let's divide 921178 by 78
We want to divide 921178 by 78.

Advancing to step 1:
78 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 78

On to step 2:
When dividing 92 by 78, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 78 away from 92, we end up with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 78

Step 3:
When dividing 141 by 78, we get 1 with a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 78 from 141 and we're left with 63.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 78

Step 4:
631 divided by 78 is 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 118.0
Deduct 624 from 631 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 78

Moving on to step 5:
When dividing 77 by 78, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 1180.0
If we subtract 0 from 77, we get 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 78

Step 6:
When dividing 778 by 78, we get 9 with a remainder of 76.
Use 9 as the next digit of our solution. 
Result so far: 11809.0
The remainder is 76 after subtracting 702 from 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 7:
When dividing 760 by 78, we get 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 11809.9
Deduct 702 from 760 and we're left 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.

Step 8:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 11809.97
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.

Let's proceed to step 9:
When dividing 340 by 78, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 11809.974
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.

Step 10:
78 can be fit into 280 3 times, resulting in a remainder of 46.
The next digit of our result is 3. 
Result so far: 11809.9743
Deduct 234 from 280 and we're left 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.

Moving on to step 11:
460 divided by 78 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 11809.97435
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 11809.974358
The remainder is 76 after subtracting 624 from 700.
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 13:
If we divide 760 by 78, we get 9 and a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 11809.9743589
Deduct 702 from 760 and we're left 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.

On to step 14:
78 goes into 580 7 times with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 11809.97435897
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The quotient of the division is 11809.97435897, and the remainder is 3.4e-08.
