We look at the division of 42345289 by 539 
We want to figure out the number of times 42345289 can be divided by 539.

Going ahead to step 1:
4 divided by 539 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 539

Let's proceed to step 2:
If we divide 42 by 539, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 539

On to step 3:
When dividing 423 by 539, we get 0 with a remainder of 423.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 423 and we're left with 423.
Bring next digit (4) of the dividend behind the 423 and repeat the process: 4234 / 539

Let's proceed to step 4:
If we divide 4234 by 539, we get 7 and a remainder of 461.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 3773 from 4234 to get 461.
Bring next digit (5) of the dividend behind the 461 and repeat the process: 4615 / 539

On to step 5:
4615 divided by 539 is 8 with a remainder of 303.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we subtract 4312 from 4615, we get 303.
Grab the next digit (2) from the dividend, add it to 303, then carry on: 3032 / 539

Moving on to step 6:
539 can be fit into 3032 5 times, resulting in a remainder of 337.
Use 5 as the next digit of our solution. 
Result so far: 785.0
Subtracting 2695 from 3032 leaves us with 337.
Fetch the next digit (8) from the dividend, attach it to 337 and continue: 3378 / 539

Moving on to step 7:
If we divide 3378 by 539, we get 6 and a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 7856.0
Subtracting 3234 from 3378 leaves us with 144.
Fetch the next digit (9) from the dividend, attach it to 144 and continue: 1449 / 539

Step 8:
1449 divided by 539 is 2 with a remainder of 371.
Use 2 as the next digit of our solution. 
Result so far: 78562.0
If we take 1078 away from 1449, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Let's proceed to step 9:
3710 divided by 539 is 6 with a remainder of 476.
Record the quotient 6 as the next digit in the result. 
Result so far: 78562.6
Subtracting 3234 from 3710 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Advancing to step 10:
If we divide 4760 by 539, we get 8 and a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 78562.68
Deduct 4312 from 4760 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 11:
When dividing 4480 by 539, we get 8 with a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 78562.688
Subtract 4312 from 4480 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 78562.688 with a remainder of 0.0168.
