We look at the division of 42540219 by 248 
Let's see how many times 248 fits into 42540219.

Step 1:
When dividing 4 by 248, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 248

Let's proceed to step 2:
The number 248 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 248

Moving on to step 3:
425 divided by 248 is 1 with a remainder of 177.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 248 from 425 and we're left with 177.
Grab the next digit (4) from the dividend, add it to 177, then carry on: 1774 / 248

On to step 4:
1774 divided by 248 is 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 1736 away from 1774, we end up with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 248

Going ahead to step 5:
When dividing 380 by 248, we get 1 with a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 171.0
Deduct 248 from 380 and we're left with 132.
Append the next digit (2) from the dividend to 132 and continue with: 1322 / 248

Advancing to step 6:
The number 248 fits into 1322 5 times, leaving a remainder of 82.
Write down 5 as next digit of the result. 
Result so far: 1715.0
The remainder is 82 after subtracting 1240 from 1322.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 248

Going ahead to step 7:
248 can be fit into 821 3 times, resulting in a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 17153.0
The remainder is 77 after subtracting 744 from 821.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 248

Step 8:
248 goes into 779 3 times with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 171533.0
The remainder is 35 after subtracting 744 from 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
248 can be fit into 350 1 times, resulting in a remainder of 102.
Record the quotient 1 as the next digit in the result. 
Result so far: 171533.1
Deduct 248 from 350 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 10:
When dividing 1020 by 248, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 171533.14
Deduct 992 from 1020 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.

Going ahead to step 11:
248 goes into 280 1 times with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 171533.141
Subtracting 248 from 280 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
If we divide 320 by 248, we get 1 and a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 171533.1411
If we subtract 248 from 320, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 171533.1411 with a balance of 0.00072.
