3319823 ÷ 725 
The aim is to understand the frequency of 725 in 3319823.

Let's proceed to step 1:
If we divide 3 by 725, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 725

Step 2:
The number 725 fits into 33 0 times, leaving a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 725

Going ahead to step 3:
The number 725 fits into 331 0 times, leaving a remainder of 331.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 331, we end up with 331.
Grab the next digit (9) from the dividend, add it to 331, then carry on: 3319 / 725

On to step 4:
725 can be fit into 3319 4 times, resulting in a remainder of 419.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 2900 from 3319 and we're left with 419.
Include the next digit (8) from the dividend after 419, then repeat: 4198 / 725

On to step 5:
If we divide 4198 by 725, we get 5 and a remainder of 573.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we take 3625 away from 4198, we end up with 573.
Bring next digit (2) of the dividend behind the 573 and repeat the process: 5732 / 725

Step 6:
5732 divided by 725 is 7 with a remainder of 657.
Put 7 as the next digit of the answer. 
Result so far: 457.0
Subtracting 5075 from 5732 leaves us with 657.
Append the next digit (3) from the dividend to 657 and continue with: 6573 / 725

Step 7:
If we divide 6573 by 725, we get 9 and a remainder of 48.
The next digit of our result is 9. 
Result so far: 4579.0
If we subtract 6525 from 6573, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
The number 725 fits into 480 0 times, leaving a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 4579.0
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 9:
The number 725 fits into 4800 6 times, leaving a remainder of 450.
Record the quotient 6 as the next digit in the result. 
Result so far: 4579.06
Subtracting 4350 from 4800 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 10:
725 can be fit into 4500 6 times, resulting in a remainder of 150.
Write down 6 as next digit of the result. 
Result so far: 4579.066
Deduct 4350 from 4500 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.

After the division, we end up with 4579.066 and a remainder of 0.015.
