556542 ÷ 42 
We want to divide 556542 by 42.

Step 1:
42 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 42

Going ahead to step 2:
55 divided by 42 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 42 from 55, we get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 42

Step 3:
When dividing 136 by 42, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 126 from 136 and we're left with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 42

Step 4:
105 divided by 42 is 2 with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Deduct 84 from 105 and we're left with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 42

Let's proceed to step 5:
The number 42 fits into 214 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 1325.0
Subtract 210 from 214 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 42

On to step 6:
42 goes into 42 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 13251.0
If we take 42 away from 42, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
The number 42 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13251.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 42 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13251.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 13251.0 with a remaining 0.0.
