We're dividing 7224719 by 526 
The aim is to understand the frequency of 526 in 7224719.

Let's proceed to step 1:
7 divided by 526 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 526

Moving on to step 2:
72 divided by 526 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 526

Going ahead to step 3:
When dividing 722 by 526, we get 1 with a remainder of 196.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 196 after subtracting 526 from 722.
Bring next digit (4) of the dividend behind the 196 and repeat the process: 1964 / 526

Let's proceed to step 4:
526 goes into 1964 3 times with a remainder of 386.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1578 from 1964, we get 386.
Bring next digit (7) of the dividend behind the 386 and repeat the process: 3867 / 526

Advancing to step 5:
When dividing 3867 by 526, we get 7 with a remainder of 185.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
If we subtract 3682 from 3867, we get 185.
Take the next digit (1) from the dividend and append it to 185, then repeat: 1851 / 526

On to step 6:
526 can be fit into 1851 3 times, resulting in a remainder of 273.
The next digit of our result is 3. 
Result so far: 1373.0
If we take 1578 away from 1851, we end up with 273.
Append the next digit (9) from the dividend to 273 and continue with: 2739 / 526

Step 7:
If we divide 2739 by 526, we get 5 and a remainder of 109.
Write down 5 as next digit of the result. 
Result so far: 13735.0
Deduct 2630 from 2739 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 8:
1090 divided by 526 is 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 13735.2
The remainder is 38 after subtracting 1052 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
If we divide 380 by 526, we get 0 and a remainder of 380.
The next digit of our result is 0. 
Result so far: 13735.2
If we subtract 0 from 380, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 10:
If we divide 3800 by 526, we get 7 and a remainder of 118.
Put 7 as the next digit of the answer. 
Result so far: 13735.207
If we take 3682 away from 3800, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 11:
526 goes into 1180 2 times with a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 13735.2072
If we take 1052 away from 1180, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 12:
526 can be fit into 1280 2 times, resulting in a remainder of 228.
Record the quotient 2 as the next digit in the result. 
Result so far: 13735.20722
Deduct 1052 from 1280 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

After the division, we end up with 13735.20722 and a remainder of 0.000228.
