We divide 90813237 by 252
The aim is to understand the frequency of 252 in 90813237.

Step 1:
If we divide 9 by 252, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 252

On to step 2:
If we divide 90 by 252, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Fetch the next digit (8) from the dividend, attach it to 90 and continue: 908 / 252

Going ahead to step 3:
252 goes into 908 3 times with a remainder of 152.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 756 from 908 and we're left with 152.
Grab the next digit (1) from the dividend, add it to 152, then carry on: 1521 / 252

Step 4:
When dividing 1521 by 252, we get 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 36.0
The remainder is 9 after subtracting 1512 from 1521.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 252

Moving on to step 5:
When dividing 93 by 252, we get 0 with a remainder of 93.
Use 0 as the next digit of our solution. 
Result so far: 360.0
Deduct 0 from 93 and we're left with 93.
Take the next digit (2) from the dividend and append it to 93, then repeat: 932 / 252

Let's proceed to step 6:
The number 252 fits into 932 3 times, leaving a remainder of 176.
Use 3 as the next digit of our solution. 
Result so far: 3603.0
If we subtract 756 from 932, we get 176.
Bring next digit (3) of the dividend behind the 176 and repeat the process: 1763 / 252

Going ahead to step 7:
When dividing 1763 by 252, we get 6 with a remainder of 251.
The next digit of our result is 6. 
Result so far: 36036.0
Subtracting 1512 from 1763 leaves us with 251.
Grab the next digit (7) from the dividend, add it to 251, then carry on: 2517 / 252

Going ahead to step 8:
If we divide 2517 by 252, we get 9 and a remainder of 249.
The number 9 becomes the next digit in our result. 
Result so far: 360369.0
Subtracting 2268 from 2517 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Let's proceed to step 9:
252 can be fit into 2490 9 times, resulting in a remainder of 222.
Record the quotient 9 as the next digit in the result. 
Result so far: 360369.9
The remainder is 222 after subtracting 2268 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 10:
When dividing 2220 by 252, we get 8 with a remainder of 204.
The number 8 becomes the next digit in our result. 
Result so far: 360369.98
If we subtract 2016 from 2220, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 11:
The number 252 fits into 2040 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 360369.988
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.

In conclusion, the division gives 360369.988 with a balance of 0.0024.
