489760 divided by 42 
We're looking to find how many times 42 goes into 489760.

On to step 1:
4 divided by 42 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 42

On to step 2:
42 goes into 48 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 42 from 48 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 42

Let's proceed to step 3:
If we divide 69 by 42, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 42 from 69 leaves us with 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 42

Let's proceed to step 4:
42 can be fit into 277 6 times, resulting in a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we subtract 252 from 277, we get 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 42

Going ahead to step 5:
256 divided by 42 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 1166.0
If we subtract 252 from 256, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 42

Step 6:
42 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 11660.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
If we divide 400 by 42, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 11660.9
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 11660.95
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 11660.952
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
160 divided by 42 is 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 11660.9523
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
340 divided by 42 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 11660.95238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
When dividing 40 by 42, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 11660.95238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 11660.9523809
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 11660.95238095
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 11660.95238095 with a remaining 1e-08.
