We look at the division of 18256945 by 456 
We're looking to find how many times 456 goes into 18256945.

Going ahead to step 1:
456 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 456

Step 2:
456 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 456

Advancing to step 3:
If we divide 182 by 456, we get 0 and a remainder of 182.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 182, we end up with 182.
Fetch the next digit (5) from the dividend, attach it to 182 and continue: 1825 / 456

Going ahead to step 4:
1825 divided by 456 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 1 after subtracting 1824 from 1825.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 456

Step 5:
456 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 16, we end up with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 456

Going ahead to step 6:
The number 456 fits into 169 0 times, leaving a remainder of 169.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
If we subtract 0 from 169, we get 169.
Bring next digit (4) of the dividend behind the 169 and repeat the process: 1694 / 456

Step 7:
If we divide 1694 by 456, we get 3 and a remainder of 326.
The number 3 becomes the next digit in our result. 
Result so far: 4003.0
If we take 1368 away from 1694, we end up with 326.
Grab the next digit (5) from the dividend, add it to 326, then carry on: 3265 / 456

Advancing to step 8:
3265 divided by 456 is 7 with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 40037.0
If we subtract 3192 from 3265, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 9:
456 goes into 730 1 times with a remainder of 274.
Record the quotient 1 as the next digit in the result. 
Result so far: 40037.1
The remainder is 274 after subtracting 456 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 10:
456 can be fit into 2740 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 40037.16
If we subtract 2736 from 2740, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
40 divided by 456 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 40037.16
Subtracting 0 from 40 leaves us with 40.
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 12:
456 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 40037.16
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 40037.16, with a leftover of 0.004.
