We look at the division of 542434 by 78 
We want to figure out the number of times 542434 can be divided by 78.

On to step 1:
78 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 78

Advancing to step 2:
78 can be fit into 54 0 times, resulting in a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 78

On to step 3:
542 divided by 78 is 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 468 from 542 and we're left with 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 78

Moving on to step 4:
744 divided by 78 is 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Deduct 702 from 744 and we're left with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 78

On to step 5:
The number 78 fits into 423 5 times, leaving a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 695.0
Deduct 390 from 423 and we're left with 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 78

Going ahead to step 6:
When dividing 334 by 78, we get 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 6954.0
If we subtract 312 from 334, we 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.

Going ahead to step 7:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 6954.2
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
When dividing 640 by 78, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 6954.28
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.

Let's proceed to step 9:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 6954.282
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
If we divide 40 by 78, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 6954.282
Subtracting 0 from 40 leaves us 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.

Advancing to step 11:
If we divide 400 by 78, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 6954.28205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
78 goes into 100 1 times with a remainder of 22.
The next digit of our result is 1. 
Result so far: 6954.282051
Subtracting 78 from 100 leaves us 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.

Let's proceed to step 13:
220 divided by 78 is 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 6954.2820512
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:
If we divide 640 by 78, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 6954.28205128
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.

In conclusion, the division gives 6954.28205128 with a balance of 1.6e-08.
