288436 divided by 45 
Let's see how many times 45 fits into 288436.

Step 1:
2 divided by 45 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 45

On to step 2:
If we divide 28 by 45, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 45

Let's proceed to step 3:
If we divide 288 by 45, we get 6 and a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 18 after subtracting 270 from 288.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 45

Advancing to step 4:
When dividing 184 by 45, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we subtract 180 from 184, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 45

Advancing to step 5:
The number 45 fits into 43 0 times, leaving a remainder of 43.
The next digit of our result is 0. 
Result so far: 640.0
If we subtract 0 from 43, we get 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 45

Step 6:
When dividing 436 by 45, we get 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 6409.0
If we take 405 away from 436, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
45 can be fit into 310 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 6409.6
If we subtract 270 from 310, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 6409.68
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 45, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 6409.688
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 6409.688, with a leftover of 0.004.
