We divide 31658991 by 825
The aim is to understand the frequency of 825 in 31658991.

Let's proceed to step 1:
The number 825 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 825

Moving on to step 2:
825 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 825

Moving on to step 3:
The number 825 fits into 316 0 times, leaving a remainder of 316.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 316, we end up with 316.
Bring next digit (5) of the dividend behind the 316 and repeat the process: 3165 / 825

Step 4:
If we divide 3165 by 825, we get 3 and a remainder of 690.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 2475 from 3165 leaves us with 690.
Grab the next digit (8) from the dividend, add it to 690, then carry on: 6908 / 825

On to step 5:
If we divide 6908 by 825, we get 8 and a remainder of 308.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
The remainder is 308 after subtracting 6600 from 6908.
Bring next digit (9) of the dividend behind the 308 and repeat the process: 3089 / 825

Let's proceed to step 6:
825 can be fit into 3089 3 times, resulting in a remainder of 614.
The next digit of our result is 3. 
Result so far: 383.0
Subtract 2475 from 3089 to get 614.
Bring next digit (9) of the dividend behind the 614 and repeat the process: 6149 / 825

Let's proceed to step 7:
825 can be fit into 6149 7 times, resulting in a remainder of 374.
The number 7 becomes the next digit in our result. 
Result so far: 3837.0
Subtract 5775 from 6149 to get 374.
Fetch the next digit (1) from the dividend, attach it to 374 and continue: 3741 / 825

Advancing to step 8:
3741 divided by 825 is 4 with a remainder of 441.
Use 4 as the next digit of our solution. 
Result so far: 38374.0
The remainder is 441 after subtracting 3300 from 3741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Advancing to step 9:
825 can be fit into 4410 5 times, resulting in a remainder of 285.
Record the quotient 5 as the next digit in the result. 
Result so far: 38374.5
The remainder is 285 after subtracting 4125 from 4410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 10:
If we divide 2850 by 825, we get 3 and a remainder of 375.
The number 3 becomes the next digit in our result. 
Result so far: 38374.53
The remainder is 375 after subtracting 2475 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 11:
825 goes into 3750 4 times with a remainder of 450.
Put 4 as the next digit of the answer. 
Result so far: 38374.534
Subtract 3300 from 3750 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 12:
If we divide 4500 by 825, we get 5 and a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 38374.5345
If we take 4125 away from 4500, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 13:
3750 divided by 825 is 4 with a remainder of 450.
Record the quotient 4 as the next digit in the result. 
Result so far: 38374.53454
Subtracting 3300 from 3750 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 14:
If we divide 4500 by 825, we get 5 and a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 38374.534545
The remainder is 375 after subtracting 4125 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 15:
825 goes into 3750 4 times with a remainder of 450.
Put 4 as the next digit of the answer. 
Result so far: 38374.5345454
Subtracting 3300 from 3750 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 16:
825 goes into 4500 5 times with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 38374.53454545
If we take 4125 away from 4500, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

The quotient of the division is 38374.53454545, and the remainder is 3.75e-07.
