We divide 38726287 by 526
The aim is to understand the frequency of 526 in 38726287.

On to step 1:
When dividing 3 by 526, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 526

Advancing to step 2:
38 divided by 526 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 526

Step 3:
526 can be fit into 387 0 times, resulting in a remainder of 387.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 387 leaves us with 387.
Fetch the next digit (2) from the dividend, attach it to 387 and continue: 3872 / 526

Moving on to step 4:
If we divide 3872 by 526, we get 7 and a remainder of 190.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 190 after subtracting 3682 from 3872.
Bring next digit (6) of the dividend behind the 190 and repeat the process: 1906 / 526

Let's proceed to step 5:
526 goes into 1906 3 times with a remainder of 328.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 328 after subtracting 1578 from 1906.
Bring next digit (2) of the dividend behind the 328 and repeat the process: 3282 / 526

Advancing to step 6:
526 can be fit into 3282 6 times, resulting in a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 736.0
The remainder is 126 after subtracting 3156 from 3282.
Grab the next digit (8) from the dividend, add it to 126, then carry on: 1268 / 526

On to step 7:
526 can be fit into 1268 2 times, resulting in a remainder of 216.
Write down 2 as next digit of the result. 
Result so far: 7362.0
Subtract 1052 from 1268 to get 216.
Bring next digit (7) of the dividend behind the 216 and repeat the process: 2167 / 526

Moving on to step 8:
When dividing 2167 by 526, we get 4 with a remainder of 63.
Write down 4 as next digit of the result. 
Result so far: 73624.0
Subtracting 2104 from 2167 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 9:
630 divided by 526 is 1 with a remainder of 104.
Record the quotient 1 as the next digit in the result. 
Result so far: 73624.1
Deduct 526 from 630 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.

Step 10:
526 can be fit into 1040 1 times, resulting in a remainder of 514.
The number 1 becomes the next digit in our result. 
Result so far: 73624.11
If we take 526 away from 1040, we end up 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.

The final outcome is 73624.11, with a leftover of 0.514.
