We're dividing 81092960 by 522 
The aim is to understand the frequency of 522 in 81092960.

Moving on to step 1:
8 divided by 522 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 522

Advancing to step 2:
The number 522 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 522

Advancing to step 3:
522 can be fit into 810 1 times, resulting in a remainder of 288.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 522 from 810, we get 288.
Grab the next digit (9) from the dividend, add it to 288, then carry on: 2889 / 522

Let's proceed to step 4:
522 goes into 2889 5 times with a remainder of 279.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 2610 from 2889 to get 279.
Take the next digit (2) from the dividend and append it to 279, then repeat: 2792 / 522

Step 5:
522 can be fit into 2792 5 times, resulting in a remainder of 182.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
Subtract 2610 from 2792 to get 182.
Take the next digit (9) from the dividend and append it to 182, then repeat: 1829 / 522

Step 6:
The number 522 fits into 1829 3 times, leaving a remainder of 263.
Write down 3 as next digit of the result. 
Result so far: 1553.0
If we subtract 1566 from 1829, we get 263.
Bring next digit (6) of the dividend behind the 263 and repeat the process: 2636 / 522

Step 7:
The number 522 fits into 2636 5 times, leaving a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 15535.0
The remainder is 26 after subtracting 2610 from 2636.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 522

On to step 8:
522 goes into 260 0 times with a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 155350.0
Subtracting 0 from 260 leaves us 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 9:
When dividing 2600 by 522, we get 4 with a remainder of 512.
Record the quotient 4 as the next digit in the result. 
Result so far: 155350.4
Subtract 2088 from 2600 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 10:
When dividing 5120 by 522, we get 9 with a remainder of 422.
Record the quotient 9 as the next digit in the result. 
Result so far: 155350.49
If we subtract 4698 from 5120, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Advancing to step 11:
522 goes into 4220 8 times with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 155350.498
Subtracting 4176 from 4220 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 12:
440 divided by 522 is 0 with a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 155350.498
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 13:
When dividing 4400 by 522, we get 8 with a remainder of 224.
Record the quotient 8 as the next digit in the result. 
Result so far: 155350.49808
Subtracting 4176 from 4400 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 14:
If we divide 2240 by 522, we get 4 and a remainder of 152.
Put 4 as the next digit of the answer. 
Result so far: 155350.498084
Deduct 2088 from 2240 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 15:
If we divide 1520 by 522, we get 2 and a remainder of 476.
The number 2 becomes the next digit in our result. 
Result so far: 155350.4980842
Subtract 1044 from 1520 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 16:
When dividing 4760 by 522, we get 9 with a remainder of 62.
The next digit of our result is 9. 
Result so far: 155350.49808429
Subtracting 4698 from 4760 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 155350.49808429 with a balance of 6.2e-08.
