18403520 divided by 452 
Let's see how many times 452 fits into 18403520.

On to step 1:
If we divide 1 by 452, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 452

Moving on to step 2:
When dividing 18 by 452, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 452

Going ahead to step 3:
452 can be fit into 184 0 times, resulting in a remainder of 184.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 184 after subtracting 0 from 184.
Take the next digit (0) from the dividend and append it to 184, then repeat: 1840 / 452

Step 4:
452 goes into 1840 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 1808 away from 1840, we end up with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 452

Advancing to step 5:
323 divided by 452 is 0 with a remainder of 323.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
The remainder is 323 after subtracting 0 from 323.
Include the next digit (5) from the dividend after 323, then repeat: 3235 / 452

Advancing to step 6:
452 goes into 3235 7 times with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 407.0
The remainder is 71 after subtracting 3164 from 3235.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 452

Moving on to step 7:
452 can be fit into 712 1 times, resulting in a remainder of 260.
The next digit of our result is 1. 
Result so far: 4071.0
The remainder is 260 after subtracting 452 from 712.
Take the next digit (0) from the dividend and append it to 260, then repeat: 2600 / 452

Advancing to step 8:
The number 452 fits into 2600 5 times, leaving a remainder of 340.
The next digit of our result is 5. 
Result so far: 40715.0
If we subtract 2260 from 2600, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 9:
If we divide 3400 by 452, we get 7 and a remainder of 236.
Write down 7 as next digit of the result. 
Result so far: 40715.7
If we subtract 3164 from 3400, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 10:
The number 452 fits into 2360 5 times, leaving a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 40715.75
If we subtract 2260 from 2360, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
452 goes into 1000 2 times with a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 40715.752
If we subtract 904 from 1000, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 12:
452 goes into 960 2 times with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 40715.7522
The remainder is 56 after subtracting 904 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 40715.7522 with a remainder of 0.00056.
