We look at the division of 9623898 by 725 
The aim is to understand the frequency of 725 in 9623898.

Let's proceed to step 1:
725 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 725

Moving on to step 2:
96 divided by 725 is 0 with a remainder of 96.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 96 to get 96.
Grab the next digit (2) from the dividend, add it to 96, then carry on: 962 / 725

Advancing to step 3:
725 can be fit into 962 1 times, resulting in a remainder of 237.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 725 from 962 to get 237.
Fetch the next digit (3) from the dividend, attach it to 237 and continue: 2373 / 725

Step 4:
725 goes into 2373 3 times with a remainder of 198.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 2175 from 2373 to get 198.
Fetch the next digit (8) from the dividend, attach it to 198 and continue: 1988 / 725

Step 5:
725 can be fit into 1988 2 times, resulting in a remainder of 538.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Subtract 1450 from 1988 to get 538.
Append the next digit (9) from the dividend to 538 and continue with: 5389 / 725

On to step 6:
725 goes into 5389 7 times with a remainder of 314.
Record the quotient 7 as the next digit in the result. 
Result so far: 1327.0
If we take 5075 away from 5389, we end up with 314.
Append the next digit (8) from the dividend to 314 and continue with: 3148 / 725

On to step 7:
725 goes into 3148 4 times with a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 13274.0
If we subtract 2900 from 3148, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 8:
725 can be fit into 2480 3 times, resulting in a remainder of 305.
Record the quotient 3 as the next digit in the result. 
Result so far: 13274.3
Subtract 2175 from 2480 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 9:
3050 divided by 725 is 4 with a remainder of 150.
Record the quotient 4 as the next digit in the result. 
Result so far: 13274.34
Subtracting 2900 from 3050 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 10:
When dividing 1500 by 725, we get 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 13274.342
If we take 1450 away from 1500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
725 goes into 500 0 times with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 13274.342
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 12:
The number 725 fits into 5000 6 times, leaving a remainder of 650.
Record the quotient 6 as the next digit in the result. 
Result so far: 13274.34206
Subtracting 4350 from 5000 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 13:
The number 725 fits into 6500 8 times, leaving a remainder of 700.
Use 8 as the next digit of our solution. 
Result so far: 13274.342068
Subtracting 5800 from 6500 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 14:
The number 725 fits into 7000 9 times, leaving a remainder of 475.
The next digit of our result is 9. 
Result so far: 13274.3420689
Subtract 6525 from 7000 to get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Advancing to step 15:
The number 725 fits into 4750 6 times, leaving a remainder of 400.
Record the quotient 6 as the next digit in the result. 
Result so far: 13274.34206896
Subtract 4350 from 4750 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 13274.34206896 with a balance of 4e-07.
