497963 ÷ 42 
Let's see how many times 42 fits into 497963.

Going ahead to step 1:
42 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 42

On to step 2:
The number 42 fits into 49 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 42 from 49, we get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 42

Going ahead to step 3:
77 divided by 42 is 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 42 from 77 and we're left with 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 42

Step 4:
359 divided by 42 is 8 with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 118.0
Deduct 336 from 359 and we're left with 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 42

Advancing to step 5:
236 divided by 42 is 5 with a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 1185.0
If we take 210 away from 236, we end up with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 42

Advancing to step 6:
When dividing 263 by 42, we get 6 with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 11856.0
The remainder is 11 after subtracting 252 from 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
When dividing 110 by 42, we get 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 11856.2
Deduct 84 from 110 and we're left with 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 8:
When dividing 260 by 42, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 11856.26
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
When dividing 80 by 42, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 11856.261
If we take 42 away from 80, we end up 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.

Going ahead to step 10:
If we divide 380 by 42, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 11856.2619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
If we divide 20 by 42, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11856.2619
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
42 goes into 200 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 11856.261904
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
When dividing 320 by 42, we get 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 11856.2619047
If we subtract 294 from 320, we 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.

On to step 14:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 11856.26190476
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 11856.26190476 and a remainder of 8e-09.
