We look at the division of 52221304 by 925 
The aim is to understand the frequency of 925 in 52221304.

Moving on to step 1:
The number 925 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 925

Advancing to step 2:
If we divide 52 by 925, we get 0 and a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Append the next digit (2) from the dividend to 52 and continue with: 522 / 925

Let's proceed to step 3:
The number 925 fits into 522 0 times, leaving a remainder of 522.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 522 after subtracting 0 from 522.
Grab the next digit (2) from the dividend, add it to 522, then carry on: 5222 / 925

Going ahead to step 4:
The number 925 fits into 5222 5 times, leaving a remainder of 597.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4625 from 5222 to get 597.
Include the next digit (1) from the dividend after 597, then repeat: 5971 / 925

Moving on to step 5:
5971 divided by 925 is 6 with a remainder of 421.
The next digit of our result is 6. 
Result so far: 56.0
Subtracting 5550 from 5971 leaves us with 421.
Include the next digit (3) from the dividend after 421, then repeat: 4213 / 925

On to step 6:
4213 divided by 925 is 4 with a remainder of 513.
The next digit of our result is 4. 
Result so far: 564.0
If we take 3700 away from 4213, we end up with 513.
Bring next digit (0) of the dividend behind the 513 and repeat the process: 5130 / 925

Moving on to step 7:
When dividing 5130 by 925, we get 5 with a remainder of 505.
Use 5 as the next digit of our solution. 
Result so far: 5645.0
Subtracting 4625 from 5130 leaves us with 505.
Include the next digit (4) from the dividend after 505, then repeat: 5054 / 925

On to step 8:
When dividing 5054 by 925, we get 5 with a remainder of 429.
Use 5 as the next digit of our solution. 
Result so far: 56455.0
The remainder is 429 after subtracting 4625 from 5054.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Advancing to step 9:
If we divide 4290 by 925, we get 4 and a remainder of 590.
Put 4 as the next digit of the answer. 
Result so far: 56455.4
Subtract 3700 from 4290 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 10:
925 goes into 5900 6 times with a remainder of 350.
The number 6 becomes the next digit in our result. 
Result so far: 56455.46
The remainder is 350 after subtracting 5550 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 11:
925 can be fit into 3500 3 times, resulting in a remainder of 725.
Write down 3 as next digit of the result. 
Result so far: 56455.463
Subtracting 2775 from 3500 leaves us with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Advancing to step 12:
The number 925 fits into 7250 7 times, leaving a remainder of 775.
Record the quotient 7 as the next digit in the result. 
Result so far: 56455.4637
Deduct 6475 from 7250 and we're left with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

On to step 13:
7750 divided by 925 is 8 with a remainder of 350.
Put 8 as the next digit of the answer. 
Result so far: 56455.46378
Deduct 7400 from 7750 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 14:
3500 divided by 925 is 3 with a remainder of 725.
Record the quotient 3 as the next digit in the result. 
Result so far: 56455.463783
If we take 2775 away from 3500, we end up with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Step 15:
925 can be fit into 7250 7 times, resulting in a remainder of 775.
Write down 7 as next digit of the result. 
Result so far: 56455.4637837
If we take 6475 away from 7250, we end up with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Let's proceed to step 16:
When dividing 7750 by 925, we get 8 with a remainder of 350.
Put 8 as the next digit of the answer. 
Result so far: 56455.46378378
The remainder is 350 after subtracting 7400 from 7750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final outcome is 56455.46378378, with a leftover of 3.5e-07.
