We look at the division of 73803854 by 252 
The aim is to understand the frequency of 252 in 73803854.

Step 1:
When dividing 7 by 252, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 252

Step 2:
252 can be fit into 73 0 times, resulting in a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 252

Moving on to step 3:
When dividing 738 by 252, we get 2 with a remainder of 234.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 504 from 738 and we're left with 234.
Fetch the next digit (0) from the dividend, attach it to 234 and continue: 2340 / 252

Moving on to step 4:
252 goes into 2340 9 times with a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 2268 away from 2340, we end up with 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 252

Advancing to step 5:
If we divide 723 by 252, we get 2 and a remainder of 219.
The number 2 becomes the next digit in our result. 
Result so far: 292.0
If we take 504 away from 723, we end up with 219.
Append the next digit (8) from the dividend to 219 and continue with: 2198 / 252

Step 6:
If we divide 2198 by 252, we get 8 and a remainder of 182.
Use 8 as the next digit of our solution. 
Result so far: 2928.0
The remainder is 182 after subtracting 2016 from 2198.
Take the next digit (5) from the dividend and append it to 182, then repeat: 1825 / 252

On to step 7:
When dividing 1825 by 252, we get 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 29287.0
The remainder is 61 after subtracting 1764 from 1825.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 252

Step 8:
When dividing 614 by 252, we get 2 with a remainder of 110.
Use 2 as the next digit of our solution. 
Result so far: 292872.0
If we subtract 504 from 614, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 9:
If we divide 1100 by 252, we get 4 and a remainder of 92.
Record the quotient 4 as the next digit in the result. 
Result so far: 292872.4
If we take 1008 away from 1100, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
When dividing 920 by 252, we get 3 with a remainder of 164.
Use 3 as the next digit of our solution. 
Result so far: 292872.43
If we subtract 756 from 920, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 11:
The number 252 fits into 1640 6 times, leaving a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 292872.436
The remainder is 128 after subtracting 1512 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 12:
252 can be fit into 1280 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 292872.4365
The remainder is 20 after subtracting 1260 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
When dividing 200 by 252, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 292872.4365
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 14:
When dividing 2000 by 252, we get 7 with a remainder of 236.
Use 7 as the next digit of our solution. 
Result so far: 292872.436507
The remainder is 236 after subtracting 1764 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 15:
The number 252 fits into 2360 9 times, leaving a remainder of 92.
Record the quotient 9 as the next digit in the result. 
Result so far: 292872.4365079
Subtracting 2268 from 2360 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 16:
920 divided by 252 is 3 with a remainder of 164.
Write down 3 as next digit of the result. 
Result so far: 292872.43650793
The remainder is 164 after subtracting 756 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The final outcome is 292872.43650793, with a leftover of 1.64e-07.
