548248 ÷ 42 
We want to divide 548248 by 42.

On to step 1:
42 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 42

Moving on to step 2:
If we divide 54 by 42, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 42 away from 54, we end up with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 42

Moving on to step 3:
The number 42 fits into 128 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 13.0
If we take 126 away from 128, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 42

On to step 4:
42 can be fit into 22 0 times, resulting in a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 130.0
Subtracting 0 from 22 leaves us with 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 42

Step 5:
42 goes into 224 5 times with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 1305.0
Subtract 210 from 224 to get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 42

Going ahead to step 6:
The number 42 fits into 148 3 times, leaving a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 13053.0
Deduct 126 from 148 and we're left 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 7:
220 divided by 42 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 13053.5
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 13053.52
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
If we divide 160 by 42, we get 3 and a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 13053.523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
42 goes into 340 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 13053.5238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
42 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 13053.5238
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.

Going ahead to step 12:
42 goes into 400 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 13053.523809
Deduct 378 from 400 and we're left 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.

On to step 13:
42 goes into 220 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 13053.5238095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
42 can be fit into 100 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 13053.52380952
Subtract 84 from 100 to 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.

The final result is 13053.52380952 with a remainder of 1.6e-08.
