We divide 39566480 by 526
The aim is to understand the frequency of 526 in 39566480.

Advancing to step 1:
If we divide 3 by 526, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 526

Moving on to step 2:
If we divide 39 by 526, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 526

Step 3:
If we divide 395 by 526, we get 0 and a remainder of 395.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 395, we get 395.
Bring next digit (6) of the dividend behind the 395 and repeat the process: 3956 / 526

Going ahead to step 4:
The number 526 fits into 3956 7 times, leaving a remainder of 274.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 274 after subtracting 3682 from 3956.
Fetch the next digit (6) from the dividend, attach it to 274 and continue: 2746 / 526

Going ahead to step 5:
2746 divided by 526 is 5 with a remainder of 116.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Deduct 2630 from 2746 and we're left with 116.
Grab the next digit (4) from the dividend, add it to 116, then carry on: 1164 / 526

Let's proceed to step 6:
When dividing 1164 by 526, we get 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 752.0
Subtract 1052 from 1164 to get 112.
Include the next digit (8) from the dividend after 112, then repeat: 1128 / 526

Advancing to step 7:
When dividing 1128 by 526, we get 2 with a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 7522.0
Subtracting 1052 from 1128 leaves us with 76.
Include the next digit (0) from the dividend after 76, then repeat: 760 / 526

Going ahead to step 8:
526 goes into 760 1 times with a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 75221.0
The remainder is 234 after subtracting 526 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 9:
526 goes into 2340 4 times with a remainder of 236.
Write down 4 as next digit of the result. 
Result so far: 75221.4
Deduct 2104 from 2340 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 10:
526 can be fit into 2360 4 times, resulting in a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 75221.44
The remainder is 256 after subtracting 2104 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 75221.44, with a leftover of 0.256.
