We look at the division of 91842829 by 520 
The aim is to understand the frequency of 520 in 91842829.

Step 1:
If we divide 9 by 520, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 520

Going ahead to step 2:
The number 520 fits into 91 0 times, leaving a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Bring next digit (8) of the dividend behind the 91 and repeat the process: 918 / 520

Moving on to step 3:
The number 520 fits into 918 1 times, leaving a remainder of 398.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 520 from 918 to get 398.
Append the next digit (4) from the dividend to 398 and continue with: 3984 / 520

Let's proceed to step 4:
520 can be fit into 3984 7 times, resulting in a remainder of 344.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 3640 from 3984 to get 344.
Take the next digit (2) from the dividend and append it to 344, then repeat: 3442 / 520

On to step 5:
520 goes into 3442 6 times with a remainder of 322.
The next digit of our result is 6. 
Result so far: 176.0
Deduct 3120 from 3442 and we're left with 322.
Take the next digit (8) from the dividend and append it to 322, then repeat: 3228 / 520

Advancing to step 6:
When dividing 3228 by 520, we get 6 with a remainder of 108.
Write down 6 as next digit of the result. 
Result so far: 1766.0
If we take 3120 away from 3228, we end up with 108.
Append the next digit (2) from the dividend to 108 and continue with: 1082 / 520

Moving on to step 7:
520 can be fit into 1082 2 times, resulting in a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 17662.0
Deduct 1040 from 1082 and we're left with 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 520

Moving on to step 8:
429 divided by 520 is 0 with a remainder of 429.
Record the quotient 0 as the next digit in the result. 
Result so far: 176620.0
If we take 0 away from 429, we end up with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 9:
520 goes into 4290 8 times with a remainder of 130.
The next digit of our result is 8. 
Result so far: 176620.8
Subtracting 4160 from 4290 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 10:
520 goes into 1300 2 times with a remainder of 260.
Write down 2 as next digit of the result. 
Result so far: 176620.82
Deduct 1040 from 1300 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
When dividing 2600 by 520, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 176620.825
Subtract 2600 from 2600 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
520 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 176620.825
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
The number 520 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 176620.825
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 176620.825 with a balance of 0.0.
