516003 divided by 42 
Our goal is to divide 516003 by 42.

Moving on to step 1:
42 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 42

Moving on to step 2:
If we divide 51 by 42, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 42 from 51, we get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 42

Moving on to step 3:
When dividing 96 by 42, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 84 away from 96, we end up with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 42

Moving on to step 4:
If we divide 120 by 42, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
The remainder is 36 after subtracting 84 from 120.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 42

Moving on to step 5:
When dividing 360 by 42, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 1228.0
If we take 336 away from 360, we end up with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 42

Going ahead to step 6:
42 goes into 243 5 times with a remainder of 33.
The next digit of our result is 5. 
Result so far: 12285.0
Subtract 210 from 243 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
42 can be fit into 330 7 times, resulting in a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 12285.7
If we take 294 away from 330, 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.

Advancing 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: 12285.78
Subtract 336 from 360 to 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.

Let's proceed to step 9:
When dividing 240 by 42, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 12285.785
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
The number 42 fits into 300 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 12285.7857
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:
When dividing 60 by 42, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 12285.78571
If we take 42 away from 60, we end up 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.

Let's proceed to step 12:
When dividing 180 by 42, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 12285.785714
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
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: 12285.7857142
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.

Going ahead to step 14:
When dividing 360 by 42, we get 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 12285.78571428
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.

The quotient of the division is 12285.78571428, and the remainder is 2.4e-08.
