Let's divide 91006304 by 510
The aim is to understand the frequency of 510 in 91006304.

Let's proceed to step 1:
9 divided by 510 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 510

Moving on to step 2:
If we divide 91 by 510, we get 0 and a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 510

Let's proceed to step 3:
510 goes into 910 1 times with a remainder of 400.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 510 from 910 leaves us with 400.
Take the next digit (0) from the dividend and append it to 400, then repeat: 4000 / 510

Going ahead to step 4:
4000 divided by 510 is 7 with a remainder of 430.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 3570 from 4000 and we're left with 430.
Fetch the next digit (6) from the dividend, attach it to 430 and continue: 4306 / 510

Going ahead to step 5:
510 can be fit into 4306 8 times, resulting in a remainder of 226.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
If we take 4080 away from 4306, we end up with 226.
Append the next digit (3) from the dividend to 226 and continue with: 2263 / 510

Step 6:
If we divide 2263 by 510, we get 4 and a remainder of 223.
Use 4 as the next digit of our solution. 
Result so far: 1784.0
If we take 2040 away from 2263, we end up with 223.
Append the next digit (0) from the dividend to 223 and continue with: 2230 / 510

Going ahead to step 7:
When dividing 2230 by 510, we get 4 with a remainder of 190.
Put 4 as the next digit of the answer. 
Result so far: 17844.0
If we subtract 2040 from 2230, we get 190.
Include the next digit (4) from the dividend after 190, then repeat: 1904 / 510

Moving on to step 8:
If we divide 1904 by 510, we get 3 and a remainder of 374.
The next digit of our result is 3. 
Result so far: 178443.0
If we subtract 1530 from 1904, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 9:
If we divide 3740 by 510, we get 7 and a remainder of 170.
Use 7 as the next digit of our solution. 
Result so far: 178443.7
If we subtract 3570 from 3740, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
When dividing 1700 by 510, we get 3 with a remainder of 170.
The next digit of our result is 3. 
Result so far: 178443.73
Subtract 1530 from 1700 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 11:
510 goes into 1700 3 times with a remainder of 170.
Use 3 as the next digit of our solution. 
Result so far: 178443.733
Deduct 1530 from 1700 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 178443.733 with a balance of 0.017.
