We're dividing 8697640 by 625 
The aim is to understand the frequency of 625 in 8697640.

Going ahead to step 1:
8 divided by 625 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 625

Step 2:
If we divide 86 by 625, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (9) from the dividend, add it to 86, then carry on: 869 / 625

Step 3:
When dividing 869 by 625, we get 1 with a remainder of 244.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 625 from 869 to get 244.
Take the next digit (7) from the dividend and append it to 244, then repeat: 2447 / 625

Step 4:
625 goes into 2447 3 times with a remainder of 572.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1875 from 2447 leaves us with 572.
Fetch the next digit (6) from the dividend, attach it to 572 and continue: 5726 / 625

On to step 5:
625 can be fit into 5726 9 times, resulting in a remainder of 101.
Use 9 as the next digit of our solution. 
Result so far: 139.0
If we subtract 5625 from 5726, we get 101.
Bring next digit (4) of the dividend behind the 101 and repeat the process: 1014 / 625

On to step 6:
When dividing 1014 by 625, we get 1 with a remainder of 389.
Write down 1 as next digit of the result. 
Result so far: 1391.0
If we subtract 625 from 1014, we get 389.
Bring next digit (0) of the dividend behind the 389 and repeat the process: 3890 / 625

Advancing to step 7:
625 can be fit into 3890 6 times, resulting in a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 13916.0
If we subtract 3750 from 3890, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 8:
If we divide 1400 by 625, we get 2 and a remainder of 150.
Use 2 as the next digit of our solution. 
Result so far: 13916.2
Deduct 1250 from 1400 and we're left 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.

Going ahead to step 9:
The number 625 fits into 1500 2 times, leaving a remainder of 250.
Record the quotient 2 as the next digit in the result. 
Result so far: 13916.22
The remainder is 250 after subtracting 1250 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

In conclusion, the division gives 13916.22 with a balance of 0.25.
