9090479 ÷ 526 
The aim is to understand the frequency of 526 in 9090479.

Let's proceed to step 1:
When dividing 9 by 526, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 526

Step 2:
If we divide 90 by 526, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Append the next digit (9) from the dividend to 90 and continue with: 909 / 526

Going ahead to step 3:
526 goes into 909 1 times with a remainder of 383.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 526 from 909 to get 383.
Include the next digit (0) from the dividend after 383, then repeat: 3830 / 526

On to step 4:
526 can be fit into 3830 7 times, resulting in a remainder of 148.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 3682 from 3830 leaves us with 148.
Bring next digit (4) of the dividend behind the 148 and repeat the process: 1484 / 526

Moving on to step 5:
526 goes into 1484 2 times with a remainder of 432.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Subtract 1052 from 1484 to get 432.
Fetch the next digit (7) from the dividend, attach it to 432 and continue: 4327 / 526

Advancing to step 6:
When dividing 4327 by 526, we get 8 with a remainder of 119.
Record the quotient 8 as the next digit in the result. 
Result so far: 1728.0
Deduct 4208 from 4327 and we're left with 119.
Fetch the next digit (9) from the dividend, attach it to 119 and continue: 1199 / 526

Going ahead to step 7:
1199 divided by 526 is 2 with a remainder of 147.
The number 2 becomes the next digit in our result. 
Result so far: 17282.0
Deduct 1052 from 1199 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 8:
1470 divided by 526 is 2 with a remainder of 418.
The number 2 becomes the next digit in our result. 
Result so far: 17282.2
Subtract 1052 from 1470 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 9:
If we divide 4180 by 526, we get 7 and a remainder of 498.
Put 7 as the next digit of the answer. 
Result so far: 17282.27
Subtracting 3682 from 4180 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 10:
The number 526 fits into 4980 9 times, leaving a remainder of 246.
The next digit of our result is 9. 
Result so far: 17282.279
The remainder is 246 after subtracting 4734 from 4980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 11:
526 goes into 2460 4 times with a remainder of 356.
The next digit of our result is 4. 
Result so far: 17282.2794
If we take 2104 away from 2460, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 12:
526 can be fit into 3560 6 times, resulting in a remainder of 404.
The next digit of our result is 6. 
Result so far: 17282.27946
If we subtract 3156 from 3560, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 13:
526 goes into 4040 7 times with a remainder of 358.
Put 7 as the next digit of the answer. 
Result so far: 17282.279467
Deduct 3682 from 4040 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 14:
526 goes into 3580 6 times with a remainder of 424.
Record the quotient 6 as the next digit in the result. 
Result so far: 17282.2794676
Subtracting 3156 from 3580 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 15:
526 goes into 4240 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 17282.27946768
If we take 4208 away from 4240, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 17282.27946768 with a remaining 3.2e-08.
