We divide 39071695 by 725
The aim is to understand the frequency of 725 in 39071695.

Step 1:
If we divide 3 by 725, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 725

On to step 2:
If we divide 39 by 725, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 725

On to step 3:
390 divided by 725 is 0 with a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 390 after subtracting 0 from 390.
Grab the next digit (7) from the dividend, add it to 390, then carry on: 3907 / 725

Going ahead to step 4:
The number 725 fits into 3907 5 times, leaving a remainder of 282.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 282 after subtracting 3625 from 3907.
Fetch the next digit (1) from the dividend, attach it to 282 and continue: 2821 / 725

On to step 5:
The number 725 fits into 2821 3 times, leaving a remainder of 646.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Deduct 2175 from 2821 and we're left with 646.
Include the next digit (6) from the dividend after 646, then repeat: 6466 / 725

Moving on to step 6:
The number 725 fits into 6466 8 times, leaving a remainder of 666.
Use 8 as the next digit of our solution. 
Result so far: 538.0
If we subtract 5800 from 6466, we get 666.
Bring next digit (9) of the dividend behind the 666 and repeat the process: 6669 / 725

Moving on to step 7:
6669 divided by 725 is 9 with a remainder of 144.
Put 9 as the next digit of the answer. 
Result so far: 5389.0
Subtracting 6525 from 6669 leaves us with 144.
Take the next digit (5) from the dividend and append it to 144, then repeat: 1445 / 725

On to step 8:
1445 divided by 725 is 1 with a remainder of 720.
Record the quotient 1 as the next digit in the result. 
Result so far: 53891.0
Subtract 725 from 1445 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 9:
If we divide 7200 by 725, we get 9 and a remainder of 675.
Use 9 as the next digit of our solution. 
Result so far: 53891.9
Subtracting 6525 from 7200 leaves us with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Advancing to step 10:
The number 725 fits into 6750 9 times, leaving a remainder of 225.
Write down 9 as next digit of the result. 
Result so far: 53891.99
If we subtract 6525 from 6750, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Our division results in 53891.99 with a remaining 0.225.
