We divide 504558 by 42
Our goal is to divide 504558 by 42.

Going ahead to step 1:
5 divided by 42 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 42

Advancing to step 2:
42 goes into 50 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 42 from 50, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 42

Step 3:
If we divide 84 by 42, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 84 from 84, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 42

Step 4:
If we divide 5 by 42, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 120.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 42

Advancing to step 5:
42 can be fit into 55 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1201.0
The remainder is 13 after subtracting 42 from 55.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 42

Step 6:
The number 42 fits into 138 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 12013.0
Subtract 126 from 138 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 12013.2
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
When dividing 360 by 42, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 12013.28
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 42, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 12013.285
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
When dividing 300 by 42, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 12013.2857
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
If we divide 60 by 42, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 12013.28571
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 12013.285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
If we divide 120 by 42, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 12013.2857142
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
42 can be fit into 360 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 12013.28571428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 12013.28571428 and a remainder of 2.4e-08.
