487637 ÷ 42 
We want to figure out the number of times 487637 can be divided by 42.

Going ahead to step 1:
The number 42 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 42

Advancing to step 2:
42 goes into 48 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 42 from 48 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 42

Step 3:
The number 42 fits into 67 1 times, leaving a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 42 from 67 to get 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 42

Step 4:
The number 42 fits into 256 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 116.0
Subtracting 252 from 256 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 42

Advancing to step 5:
The number 42 fits into 43 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1161.0
If we subtract 42 from 43, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 42

On to step 6:
42 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 11610.0
If we take 0 away from 17, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
The number 42 fits into 170 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 11610.4
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
The number 42 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 11610.4
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
42 goes into 200 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 11610.404
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
42 goes into 320 7 times with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 11610.4047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
260 divided by 42 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 11610.40476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
42 goes into 80 1 times with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 11610.404761
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
42 can be fit into 380 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 11610.4047619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
When dividing 20 by 42, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11610.4047619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 11610.4047619 with a remaining 2e-08.
