Let's divide 83409612 by 252
The aim is to understand the frequency of 252 in 83409612.

On to step 1:
If we divide 8 by 252, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 252

Going ahead to step 2:
252 can be fit into 83 0 times, resulting in a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 252

Advancing to step 3:
The number 252 fits into 834 3 times, leaving a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 756 from 834 and we're left with 78.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 252

Moving on to step 4:
780 divided by 252 is 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Deduct 756 from 780 and we're left with 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 252

Step 5:
252 can be fit into 249 0 times, resulting in a remainder of 249.
Write down 0 as next digit of the result. 
Result so far: 330.0
Deduct 0 from 249 and we're left with 249.
Include the next digit (6) from the dividend after 249, then repeat: 2496 / 252

Advancing to step 6:
If we divide 2496 by 252, we get 9 and a remainder of 228.
Record the quotient 9 as the next digit in the result. 
Result so far: 3309.0
The remainder is 228 after subtracting 2268 from 2496.
Fetch the next digit (1) from the dividend, attach it to 228 and continue: 2281 / 252

Going ahead to step 7:
2281 divided by 252 is 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 33099.0
If we take 2268 away from 2281, we end up with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 252

On to step 8:
When dividing 132 by 252, we get 0 with a remainder of 132.
Record the quotient 0 as the next digit in the result. 
Result so far: 330990.0
If we take 0 away from 132, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 9:
If we divide 1320 by 252, we get 5 and a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 330990.5
The remainder is 60 after subtracting 1260 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
When dividing 600 by 252, we get 2 with a remainder of 96.
The next digit of our result is 2. 
Result so far: 330990.52
Subtracting 504 from 600 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 11:
When dividing 960 by 252, we get 3 with a remainder of 204.
The number 3 becomes the next digit in our result. 
Result so far: 330990.523
If we take 756 away from 960, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 12:
2040 divided by 252 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 330990.5238
If we subtract 2016 from 2040, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
240 divided by 252 is 0 with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 330990.5238
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 14:
252 goes into 2400 9 times with a remainder of 132.
Record the quotient 9 as the next digit in the result. 
Result so far: 330990.523809
Subtracting 2268 from 2400 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 15:
If we divide 1320 by 252, we get 5 and a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 330990.5238095
If we subtract 1260 from 1320, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 16:
When dividing 600 by 252, we get 2 with a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 330990.52380952
The remainder is 96 after subtracting 504 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final result is 330990.52380952 with a remainder of 9.6e-08.
