We look at the division of 16535966 by 526 
The aim is to understand the frequency of 526 in 16535966.

Let's proceed to step 1:
1 divided by 526 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 526

Step 2:
If we divide 16 by 526, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 526

Let's proceed to step 3:
When dividing 165 by 526, we get 0 with a remainder of 165.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 165 leaves us with 165.
Take the next digit (3) from the dividend and append it to 165, then repeat: 1653 / 526

Advancing to step 4:
If we divide 1653 by 526, we get 3 and a remainder of 75.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 1578 from 1653 and we're left with 75.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 526

Moving on to step 5:
755 divided by 526 is 1 with a remainder of 229.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 526 from 755, we get 229.
Include the next digit (9) from the dividend after 229, then repeat: 2299 / 526

Going ahead to step 6:
526 can be fit into 2299 4 times, resulting in a remainder of 195.
Use 4 as the next digit of our solution. 
Result so far: 314.0
Deduct 2104 from 2299 and we're left with 195.
Fetch the next digit (6) from the dividend, attach it to 195 and continue: 1956 / 526

Going ahead to step 7:
526 goes into 1956 3 times with a remainder of 378.
Record the quotient 3 as the next digit in the result. 
Result so far: 3143.0
Deduct 1578 from 1956 and we're left with 378.
Grab the next digit (6) from the dividend, add it to 378, then carry on: 3786 / 526

Going ahead to step 8:
The number 526 fits into 3786 7 times, leaving a remainder of 104.
The next digit of our result is 7. 
Result so far: 31437.0
Deduct 3682 from 3786 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 9:
The number 526 fits into 1040 1 times, leaving a remainder of 514.
Record the quotient 1 as the next digit in the result. 
Result so far: 31437.1
Deduct 526 from 1040 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Moving on to step 10:
If we divide 5140 by 526, we get 9 and a remainder of 406.
Write down 9 as next digit of the result. 
Result so far: 31437.19
Subtracting 4734 from 5140 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 11:
526 goes into 4060 7 times with a remainder of 378.
The number 7 becomes the next digit in our result. 
Result so far: 31437.197
The remainder is 378 after subtracting 3682 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 12:
3780 divided by 526 is 7 with a remainder of 98.
Record the quotient 7 as the next digit in the result. 
Result so far: 31437.1977
The remainder is 98 after subtracting 3682 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The quotient of the division is 31437.1977, and the remainder is 0.00098.
