We're dividing 23503611 by 406 
We want to figure out the number of times 23503611 can be divided by 406.

Step 1:
The number 406 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 406

Moving on to step 2:
The number 406 fits into 23 0 times, leaving a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 406

Step 3:
The number 406 fits into 235 0 times, leaving a remainder of 235.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 235 to get 235.
Take the next digit (0) from the dividend and append it to 235, then repeat: 2350 / 406

Step 4:
When dividing 2350 by 406, we get 5 with a remainder of 320.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 2030 from 2350 leaves us with 320.
Grab the next digit (3) from the dividend, add it to 320, then carry on: 3203 / 406

Advancing to step 5:
3203 divided by 406 is 7 with a remainder of 361.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we take 2842 away from 3203, we end up with 361.
Include the next digit (6) from the dividend after 361, then repeat: 3616 / 406

Step 6:
3616 divided by 406 is 8 with a remainder of 368.
The next digit of our result is 8. 
Result so far: 578.0
Deduct 3248 from 3616 and we're left with 368.
Bring next digit (1) of the dividend behind the 368 and repeat the process: 3681 / 406

Step 7:
406 can be fit into 3681 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 5789.0
Subtract 3654 from 3681 to get 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 406

Step 8:
If we divide 271 by 406, we get 0 and a remainder of 271.
The next digit of our result is 0. 
Result so far: 57890.0
Subtract 0 from 271 to get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 9:
406 can be fit into 2710 6 times, resulting in a remainder of 274.
Record the quotient 6 as the next digit in the result. 
Result so far: 57890.6
Subtract 2436 from 2710 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 10:
406 can be fit into 2740 6 times, resulting in a remainder of 304.
Use 6 as the next digit of our solution. 
Result so far: 57890.66
If we take 2436 away from 2740, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final result is 57890.66 with a remainder of 0.304.
