We look at the division of 21233307 by 887 
Let's see how many times 887 fits into 21233307.

Going ahead to step 1:
When dividing 2 by 887, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 887

On to step 2:
If we divide 21 by 887, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 887

Step 3:
If we divide 212 by 887, we get 0 and a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Take the next digit (3) from the dividend and append it to 212, then repeat: 2123 / 887

Let's proceed to step 4:
887 goes into 2123 2 times with a remainder of 349.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1774 from 2123 to get 349.
Include the next digit (3) from the dividend after 349, then repeat: 3493 / 887

Let's proceed to step 5:
When dividing 3493 by 887, we get 3 with a remainder of 832.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 2661 from 3493 and we're left with 832.
Take the next digit (3) from the dividend and append it to 832, then repeat: 8323 / 887

On to step 6:
887 goes into 8323 9 times with a remainder of 340.
The number 9 becomes the next digit in our result. 
Result so far: 239.0
If we take 7983 away from 8323, we end up with 340.
Grab the next digit (0) from the dividend, add it to 340, then carry on: 3400 / 887

Step 7:
The number 887 fits into 3400 3 times, leaving a remainder of 739.
Put 3 as the next digit of the answer. 
Result so far: 2393.0
If we take 2661 away from 3400, we end up with 739.
Include the next digit (7) from the dividend after 739, then repeat: 7397 / 887

Advancing to step 8:
887 can be fit into 7397 8 times, resulting in a remainder of 301.
The number 8 becomes the next digit in our result. 
Result so far: 23938.0
If we take 7096 away from 7397, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 9:
If we divide 3010 by 887, we get 3 and a remainder of 349.
Use 3 as the next digit of our solution. 
Result so far: 23938.3
Deduct 2661 from 3010 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 10:
When dividing 3490 by 887, we get 3 with a remainder of 829.
Write down 3 as next digit of the result. 
Result so far: 23938.33
If we subtract 2661 from 3490, we get 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

The final outcome is 23938.33, with a leftover of 0.829.
