We're dividing 43172892 by 252 
The aim is to understand the frequency of 252 in 43172892.

Going ahead to step 1:
252 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 252

Step 2:
252 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 252

Advancing to step 3:
252 can be fit into 431 1 times, resulting in a remainder of 179.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 252 from 431 to get 179.
Grab the next digit (7) from the dividend, add it to 179, then carry on: 1797 / 252

On to step 4:
When dividing 1797 by 252, we get 7 with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 1764 from 1797 and we're left with 33.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 252

Going ahead to step 5:
332 divided by 252 is 1 with a remainder of 80.
The next digit of our result is 1. 
Result so far: 171.0
If we subtract 252 from 332, we get 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 252

Moving on to step 6:
If we divide 808 by 252, we get 3 and a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 1713.0
Deduct 756 from 808 and we're left with 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 252

Moving on to step 7:
If we divide 529 by 252, we get 2 and a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 17132.0
Subtract 504 from 529 to get 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 252

Step 8:
The number 252 fits into 252 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 171321.0
If we take 252 away from 252, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 252, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 171321.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 252 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 171321.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 171321.0 and a remainder of 0.0.
