74392 ÷ 78 
Our goal is to divide 74392 by 78.

Step 1:
78 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 78

Step 2:
The number 78 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 78

Step 3:
78 goes into 743 9 times with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 702 from 743 leaves us with 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 78

On to step 4:
78 goes into 419 5 times with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
The remainder is 29 after subtracting 390 from 419.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 78

On to step 5:
When dividing 292 by 78, we get 3 with a remainder of 58.
The next digit of our result is 3. 
Result so far: 953.0
Subtract 234 from 292 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 6:
580 divided by 78 is 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 953.7
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 7:
78 goes into 340 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 953.74
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.

Going ahead to step 8:
The number 78 fits into 280 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 953.743
If we subtract 234 from 280, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
If we divide 460 by 78, we get 5 and a remainder of 70.
The next digit of our result is 5. 
Result so far: 953.7435
Deduct 390 from 460 and we're left 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.

Let's proceed to step 10:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 953.74358
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
760 divided by 78 is 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 953.743589
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 12:
If we divide 580 by 78, we get 7 and a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 953.7435897
Subtracting 546 from 580 leaves us 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.

Step 13:
The number 78 fits into 340 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 953.74358974
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.

The quotient of the division is 953.74358974, and the remainder is 2.8e-08.
