We divide 43239074 by 542
We're looking to find how many times 542 goes into 43239074.

Going ahead to step 1:
542 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 542

On to step 2:
542 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 542

Moving on to step 3:
542 goes into 432 0 times with a remainder of 432.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 432, we end up with 432.
Take the next digit (3) from the dividend and append it to 432, then repeat: 4323 / 542

On to step 4:
The number 542 fits into 4323 7 times, leaving a remainder of 529.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 3794 from 4323 leaves us with 529.
Fetch the next digit (9) from the dividend, attach it to 529 and continue: 5299 / 542

Advancing to step 5:
542 goes into 5299 9 times with a remainder of 421.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
If we subtract 4878 from 5299, we get 421.
Grab the next digit (0) from the dividend, add it to 421, then carry on: 4210 / 542

Let's proceed to step 6:
The number 542 fits into 4210 7 times, leaving a remainder of 416.
Use 7 as the next digit of our solution. 
Result so far: 797.0
Subtracting 3794 from 4210 leaves us with 416.
Include the next digit (7) from the dividend after 416, then repeat: 4167 / 542

Moving on to step 7:
If we divide 4167 by 542, we get 7 and a remainder of 373.
Record the quotient 7 as the next digit in the result. 
Result so far: 7977.0
If we subtract 3794 from 4167, we get 373.
Include the next digit (4) from the dividend after 373, then repeat: 3734 / 542

Going ahead to step 8:
If we divide 3734 by 542, we get 6 and a remainder of 482.
Record the quotient 6 as the next digit in the result. 
Result so far: 79776.0
If we subtract 3252 from 3734, we get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 9:
542 goes into 4820 8 times with a remainder of 484.
The next digit of our result is 8. 
Result so far: 79776.8
If we subtract 4336 from 4820, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 10:
If we divide 4840 by 542, we get 8 and a remainder of 504.
Write down 8 as next digit of the result. 
Result so far: 79776.88
Subtracting 4336 from 4840 leaves us with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

The final result is 79776.88 with a remainder of 0.504.
