548690 ÷ 42 
Our goal is to divide 548690 by 42.

Moving on to step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 42

Advancing to step 2:
42 can be fit into 54 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 12 after subtracting 42 from 54.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 42

Going ahead to step 3:
When dividing 128 by 42, we get 3 with 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.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 42

Step 4:
If we divide 26 by 42, we get 0 and a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 130.0
The remainder is 26 after subtracting 0 from 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 42

Advancing to step 5:
42 can be fit into 269 6 times, resulting in a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 1306.0
The remainder is 17 after subtracting 252 from 269.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 42

Step 6:
170 divided by 42 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 13064.0
If we take 168 away from 170, we end up 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 7:
If we divide 20 by 42, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 13064.0
If we take 0 away from 20, we end up 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.

On to step 8:
The number 42 fits into 200 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 13064.04
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.

Going ahead to step 9:
When dividing 320 by 42, we get 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 13064.047
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.

Step 10:
42 goes into 260 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 13064.0476
If we take 252 away from 260, we end up with 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:
80 divided by 42 is 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 13064.04761
Deduct 42 from 80 and we're left 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:
380 divided by 42 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 13064.047619
If we subtract 378 from 380, we get 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:
If we divide 20 by 42, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 13064.047619
Deduct 0 from 20 and we're left 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.

Going ahead to step 14:
200 divided by 42 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 13064.04761904
If we take 168 away from 200, we end up 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 13064.04761904, with a leftover of 3.2e-08.
