We look at the division of 51652214 by 725 
The aim is to understand the frequency of 725 in 51652214.

Moving on to step 1:
When dividing 5 by 725, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 725

Step 2:
The number 725 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 725

Moving on to step 3:
516 divided by 725 is 0 with a remainder of 516.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 516 leaves us with 516.
Take the next digit (5) from the dividend and append it to 516, then repeat: 5165 / 725

On to step 4:
5165 divided by 725 is 7 with a remainder of 90.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 90 after subtracting 5075 from 5165.
Include the next digit (2) from the dividend after 90, then repeat: 902 / 725

Going ahead to step 5:
725 goes into 902 1 times with a remainder of 177.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 725 from 902, we get 177.
Fetch the next digit (2) from the dividend, attach it to 177 and continue: 1772 / 725

Let's proceed to step 6:
The number 725 fits into 1772 2 times, leaving a remainder of 322.
Write down 2 as next digit of the result. 
Result so far: 712.0
The remainder is 322 after subtracting 1450 from 1772.
Take the next digit (1) from the dividend and append it to 322, then repeat: 3221 / 725

Going ahead to step 7:
3221 divided by 725 is 4 with a remainder of 321.
Put 4 as the next digit of the answer. 
Result so far: 7124.0
If we subtract 2900 from 3221, we get 321.
Grab the next digit (4) from the dividend, add it to 321, then carry on: 3214 / 725

Advancing to step 8:
725 can be fit into 3214 4 times, resulting in a remainder of 314.
Put 4 as the next digit of the answer. 
Result so far: 71244.0
If we take 2900 away from 3214, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 9:
When dividing 3140 by 725, we get 4 with a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 71244.4
Subtract 2900 from 3140 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 10:
When dividing 2400 by 725, we get 3 with a remainder of 225.
The number 3 becomes the next digit in our result. 
Result so far: 71244.43
If we take 2175 away from 2400, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 11:
If we divide 2250 by 725, we get 3 and a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 71244.433
Subtract 2175 from 2250 to 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.

Our division results in 71244.433 with a remaining 0.0075.
