We're dividing 549422 by 78 
We want to figure out the number of times 549422 can be divided by 78.

Step 1:
If we divide 5 by 78, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 78

Moving on to step 2:
The number 78 fits into 54 0 times, leaving a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 78

Step 3:
When dividing 549 by 78, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 546 from 549, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 78

Let's proceed to step 4:
If we divide 34 by 78, we get 0 and a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
The remainder is 34 after subtracting 0 from 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 78

Let's proceed to step 5:
78 goes into 342 4 times with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 704.0
If we take 312 away from 342, we end up with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 78

Moving on to step 6:
When dividing 302 by 78, we get 3 with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 7043.0
Subtract 234 from 302 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 7:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 7043.8
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 8:
If we divide 560 by 78, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 7043.87
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
If we divide 140 by 78, we get 1 and a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 7043.871
Deduct 78 from 140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
If we divide 620 by 78, we get 7 and a remainder of 74.
The next digit of our result is 7. 
Result so far: 7043.8717
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 11:
740 divided by 78 is 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 7043.87179
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
If we divide 380 by 78, we get 4 and a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 7043.871794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
The number 78 fits into 680 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 7043.8717948
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 7043.87179487
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 7043.87179487 with a remainder of 1.4e-08.
