We're dividing 248558 by 42 
Our goal is to divide 248558 by 42.

Step 1:
42 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 42

Going ahead to step 2:
If we divide 24 by 42, we get 0 and a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 42

On to step 3:
42 goes into 248 5 times with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 210 from 248, we get 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 42

On to step 4:
42 goes into 385 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we take 378 away from 385, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 42

Advancing to step 5:
When dividing 75 by 42, we get 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 591.0
Deduct 42 from 75 and we're left with 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 42

Let's proceed to step 6:
When dividing 338 by 42, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 5918.0
The remainder is 2 after subtracting 336 from 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
If we divide 20 by 42, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 5918.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 42 is 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 5918.04
The remainder is 32 after subtracting 168 from 200.
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 9:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 5918.047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
When dividing 260 by 42, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 5918.0476
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 5918.04761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
When dividing 380 by 42, we get 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 5918.047619
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
The number 42 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5918.047619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
42 goes into 200 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 5918.04761904
Subtracting 168 from 200 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.

The final outcome is 5918.04761904, with a leftover of 3.2e-08.
