We look at the division of 498463 by 42 
We want to figure out the number of times 498463 can be divided by 42.

Moving on to step 1:
When dividing 4 by 42, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 42

Advancing to step 2:
42 goes into 49 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 42 away from 49, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 42

Moving on to step 3:
When dividing 78 by 42, we get 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 42 from 78 leaves us with 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 42

On to step 4:
364 divided by 42 is 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
The remainder is 28 after subtracting 336 from 364.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 42

Going ahead to step 5:
42 can be fit into 286 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 1186.0
Deduct 252 from 286 and we're left with 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 42

Step 6:
If we divide 343 by 42, we get 8 and a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 11868.0
The remainder is 7 after subtracting 336 from 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 42 is 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 11868.1
Subtracting 42 from 70 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
If we divide 280 by 42, we get 6 and a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 11868.16
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
The number 42 fits into 280 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 11868.166
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 11868.166, with a leftover of 0.0028.
