4874239 ÷ 909 
We want to figure out the number of times 4874239 can be divided by 909.

Let's proceed to step 1:
When dividing 4 by 909, we get 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.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 909

On to step 2:
48 divided by 909 is 0 with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 909

Going ahead to step 3:
When dividing 487 by 909, we get 0 with a remainder of 487.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 487 leaves us with 487.
Include the next digit (4) from the dividend after 487, then repeat: 4874 / 909

Going ahead to step 4:
When dividing 4874 by 909, we get 5 with a remainder of 329.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 4545 from 4874, we get 329.
Take the next digit (2) from the dividend and append it to 329, then repeat: 3292 / 909

Step 5:
When dividing 3292 by 909, we get 3 with a remainder of 565.
Put 3 as the next digit of the answer. 
Result so far: 53.0
The remainder is 565 after subtracting 2727 from 3292.
Include the next digit (3) from the dividend after 565, then repeat: 5653 / 909

On to step 6:
5653 divided by 909 is 6 with a remainder of 199.
Put 6 as the next digit of the answer. 
Result so far: 536.0
Deduct 5454 from 5653 and we're left with 199.
Append the next digit (9) from the dividend to 199 and continue with: 1999 / 909

Going ahead to step 7:
909 goes into 1999 2 times with a remainder of 181.
Write down 2 as next digit of the result. 
Result so far: 5362.0
Deduct 1818 from 1999 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 8:
The number 909 fits into 1810 1 times, leaving a remainder of 901.
Use 1 as the next digit of our solution. 
Result so far: 5362.1
If we subtract 909 from 1810, we get 901.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9010, and continue the process.

On to step 9:
If we divide 9010 by 909, we get 9 and a remainder of 829.
Record the quotient 9 as the next digit in the result. 
Result so far: 5362.19
If we take 8181 away from 9010, we end up with 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

Advancing to step 10:
8290 divided by 909 is 9 with a remainder of 109.
The next digit of our result is 9. 
Result so far: 5362.199
If we take 8181 away from 8290, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

The quotient of the division is 5362.199, and the remainder is 0.0109.
