We look at the division of 40043645 by 452 
We want to figure out the number of times 40043645 can be divided by 452.

On to step 1:
When dividing 4 by 452, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 452

Let's proceed to step 2:
40 divided by 452 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 452

Going ahead to step 3:
452 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 400 leaves us with 400.
Bring next digit (4) of the dividend behind the 400 and repeat the process: 4004 / 452

Moving on to step 4:
452 can be fit into 4004 8 times, resulting in a remainder of 388.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 3616 from 4004 to get 388.
Bring next digit (3) of the dividend behind the 388 and repeat the process: 3883 / 452

Advancing to step 5:
452 can be fit into 3883 8 times, resulting in a remainder of 267.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Deduct 3616 from 3883 and we're left with 267.
Include the next digit (6) from the dividend after 267, then repeat: 2676 / 452

Step 6:
When dividing 2676 by 452, we get 5 with a remainder of 416.
The next digit of our result is 5. 
Result so far: 885.0
The remainder is 416 after subtracting 2260 from 2676.
Grab the next digit (4) from the dividend, add it to 416, then carry on: 4164 / 452

Step 7:
452 goes into 4164 9 times with a remainder of 96.
The next digit of our result is 9. 
Result so far: 8859.0
The remainder is 96 after subtracting 4068 from 4164.
Grab the next digit (5) from the dividend, add it to 96, then carry on: 965 / 452

Let's proceed to step 8:
The number 452 fits into 965 2 times, leaving a remainder of 61.
The next digit of our result is 2. 
Result so far: 88592.0
Subtract 904 from 965 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 9:
610 divided by 452 is 1 with a remainder of 158.
Record the quotient 1 as the next digit in the result. 
Result so far: 88592.1
The remainder is 158 after subtracting 452 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 10:
452 can be fit into 1580 3 times, resulting in a remainder of 224.
Put 3 as the next digit of the answer. 
Result so far: 88592.13
If we subtract 1356 from 1580, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 11:
The number 452 fits into 2240 4 times, leaving a remainder of 432.
The number 4 becomes the next digit in our result. 
Result so far: 88592.134
The remainder is 432 after subtracting 1808 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 12:
4320 divided by 452 is 9 with a remainder of 252.
Record the quotient 9 as the next digit in the result. 
Result so far: 88592.1349
If we take 4068 away from 4320, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 13:
2520 divided by 452 is 5 with a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 88592.13495
The remainder is 260 after subtracting 2260 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 14:
452 goes into 2600 5 times with a remainder of 340.
Use 5 as the next digit of our solution. 
Result so far: 88592.134955
The remainder is 340 after subtracting 2260 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

After the division, we end up with 88592.134955 and a remainder of 3.4e-05.
