485787 divided by 42 
We're looking to find how many times 42 goes into 485787.

Advancing to step 1:
4 divided by 42 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 42

Moving on to step 2:
42 can be fit into 48 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 42 from 48 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 42

Going ahead to step 3:
If we divide 65 by 42, we get 1 and a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 23 after subtracting 42 from 65.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 42

On to step 4:
The number 42 fits into 237 5 times, leaving a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtract 210 from 237 to get 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 42

Going ahead to step 5:
278 divided by 42 is 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 1156.0
If we take 252 away from 278, we end up with 26.
Include the next digit (7) from the dividend after 26, then repeat: 267 / 42

Advancing to step 6:
42 can be fit into 267 6 times, resulting in a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 11566.0
Subtracting 252 from 267 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
The number 42 fits into 150 3 times, leaving a remainder of 24.
The next digit of our result is 3. 
Result so far: 11566.3
The remainder is 24 after subtracting 126 from 150.
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 8:
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: 11566.35
Deduct 210 from 240 and we're left 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.

Let's proceed to step 9:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 11566.357
If we take 294 away from 300, we end up 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.

Going ahead to step 10:
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: 11566.3571
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 11:
The number 42 fits into 180 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 11566.35714
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 12:
The number 42 fits into 120 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 11566.357142
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.

Let's proceed to step 13:
360 divided by 42 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 11566.3571428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
240 divided by 42 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 11566.35714285
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.

After the division, we end up with 11566.35714285 and a remainder of 3e-08.
