18166033 divided by 252 
We want to figure out the number of times 18166033 can be divided by 252.

Step 1:
When dividing 1 by 252, we get 0 with 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 / 252

On to step 2:
If we divide 18 by 252, we get 0 and 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 (1) from the dividend after 18, then repeat: 181 / 252

Moving on to step 3:
If we divide 181 by 252, we get 0 and a remainder of 181.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 181 leaves us with 181.
Take the next digit (6) from the dividend and append it to 181, then repeat: 1816 / 252

Going ahead to step 4:
1816 divided by 252 is 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 1764 from 1816 and we're left with 52.
Take the next digit (6) from the dividend and append it to 52, then repeat: 526 / 252

Advancing to step 5:
The number 252 fits into 526 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 22 after subtracting 504 from 526.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 252

On to step 6:
252 can be fit into 220 0 times, resulting in a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 720.0
The remainder is 220 after subtracting 0 from 220.
Include the next digit (3) from the dividend after 220, then repeat: 2203 / 252

Step 7:
When dividing 2203 by 252, we get 8 with a remainder of 187.
The number 8 becomes the next digit in our result. 
Result so far: 7208.0
Subtract 2016 from 2203 to get 187.
Fetch the next digit (3) from the dividend, attach it to 187 and continue: 1873 / 252

Moving on to step 8:
252 goes into 1873 7 times with a remainder of 109.
Put 7 as the next digit of the answer. 
Result so far: 72087.0
The remainder is 109 after subtracting 1764 from 1873.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 9:
252 goes into 1090 4 times with a remainder of 82.
Put 4 as the next digit of the answer. 
Result so far: 72087.4
The remainder is 82 after subtracting 1008 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
820 divided by 252 is 3 with a remainder of 64.
The next digit of our result is 3. 
Result so far: 72087.43
If we take 756 away from 820, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
The number 252 fits into 640 2 times, leaving a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 72087.432
The remainder is 136 after subtracting 504 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 12:
If we divide 1360 by 252, we get 5 and a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 72087.4325
If we subtract 1260 from 1360, 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.

Moving on to step 13:
If we divide 1000 by 252, we get 3 and a remainder of 244.
Record the quotient 3 as the next digit in the result. 
Result so far: 72087.43253
If we subtract 756 from 1000, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 14:
The number 252 fits into 2440 9 times, leaving a remainder of 172.
The number 9 becomes the next digit in our result. 
Result so far: 72087.432539
Subtract 2268 from 2440 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 15:
1720 divided by 252 is 6 with a remainder of 208.
Write down 6 as next digit of the result. 
Result so far: 72087.4325396
Deduct 1512 from 1720 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 16:
252 goes into 2080 8 times with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 72087.43253968
Subtract 2016 from 2080 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 72087.43253968 and a remainder of 6.4e-08.
