We look at the division of 23903059 by 425 
The aim is to understand the frequency of 425 in 23903059.

Advancing to step 1:
The number 425 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 425

Going ahead to step 2:
If we divide 23 by 425, we get 0 and a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 425

Step 3:
425 goes into 239 0 times with a remainder of 239.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 239 after subtracting 0 from 239.
Take the next digit (0) from the dividend and append it to 239, then repeat: 2390 / 425

Let's proceed to step 4:
When dividing 2390 by 425, we get 5 with a remainder of 265.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 265 after subtracting 2125 from 2390.
Take the next digit (3) from the dividend and append it to 265, then repeat: 2653 / 425

Advancing to step 5:
When dividing 2653 by 425, we get 6 with a remainder of 103.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Deduct 2550 from 2653 and we're left with 103.
Bring next digit (0) of the dividend behind the 103 and repeat the process: 1030 / 425

Going ahead to step 6:
When dividing 1030 by 425, we get 2 with a remainder of 180.
Use 2 as the next digit of our solution. 
Result so far: 562.0
Subtract 850 from 1030 to get 180.
Append the next digit (5) from the dividend to 180 and continue with: 1805 / 425

Advancing to step 7:
When dividing 1805 by 425, we get 4 with a remainder of 105.
The next digit of our result is 4. 
Result so far: 5624.0
Subtracting 1700 from 1805 leaves us with 105.
Bring next digit (9) of the dividend behind the 105 and repeat the process: 1059 / 425

Step 8:
If we divide 1059 by 425, we get 2 and a remainder of 209.
The next digit of our result is 2. 
Result so far: 56242.0
Deduct 850 from 1059 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 9:
When dividing 2090 by 425, we get 4 with a remainder of 390.
Record the quotient 4 as the next digit in the result. 
Result so far: 56242.4
Subtract 1700 from 2090 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 10:
3900 divided by 425 is 9 with a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 56242.49
If we subtract 3825 from 3900, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
425 goes into 750 1 times with a remainder of 325.
Put 1 as the next digit of the answer. 
Result so far: 56242.491
Deduct 425 from 750 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 12:
If we divide 3250 by 425, we get 7 and a remainder of 275.
Record the quotient 7 as the next digit in the result. 
Result so far: 56242.4917
If we take 2975 away from 3250, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 13:
2750 divided by 425 is 6 with a remainder of 200.
The next digit of our result is 6. 
Result so far: 56242.49176
Deduct 2550 from 2750 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 14:
If we divide 2000 by 425, we get 4 and a remainder of 300.
Put 4 as the next digit of the answer. 
Result so far: 56242.491764
If we take 1700 away from 2000, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 15:
If we divide 3000 by 425, we get 7 and a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 56242.4917647
If we subtract 2975 from 3000, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 16:
250 divided by 425 is 0 with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 56242.4917647
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final result is 56242.4917647 with a remainder of 2.5e-07.
