80382913 ÷ 522 
The aim is to understand the frequency of 522 in 80382913.

Moving on to step 1:
When dividing 8 by 522, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 522

On to step 2:
The number 522 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 522

Advancing to step 3:
If we divide 803 by 522, we get 1 and a remainder of 281.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 522 away from 803, we end up with 281.
Fetch the next digit (8) from the dividend, attach it to 281 and continue: 2818 / 522

Advancing to step 4:
If we divide 2818 by 522, we get 5 and a remainder of 208.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2610 away from 2818, we end up with 208.
Take the next digit (2) from the dividend and append it to 208, then repeat: 2082 / 522

Advancing to step 5:
522 goes into 2082 3 times with a remainder of 516.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
The remainder is 516 after subtracting 1566 from 2082.
Take the next digit (9) from the dividend and append it to 516, then repeat: 5169 / 522

Step 6:
When dividing 5169 by 522, we get 9 with a remainder of 471.
Put 9 as the next digit of the answer. 
Result so far: 1539.0
If we subtract 4698 from 5169, we get 471.
Take the next digit (1) from the dividend and append it to 471, then repeat: 4711 / 522

Going ahead to step 7:
If we divide 4711 by 522, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 15399.0
Subtracting 4698 from 4711 leaves us with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 522

Let's proceed to step 8:
522 can be fit into 133 0 times, resulting in a remainder of 133.
Put 0 as the next digit of the answer. 
Result so far: 153990.0
If we take 0 away from 133, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 9:
1330 divided by 522 is 2 with a remainder of 286.
Record the quotient 2 as the next digit in the result. 
Result so far: 153990.2
If we subtract 1044 from 1330, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 10:
522 can be fit into 2860 5 times, resulting in a remainder of 250.
The next digit of our result is 5. 
Result so far: 153990.25
Subtract 2610 from 2860 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 11:
When dividing 2500 by 522, we get 4 with a remainder of 412.
Put 4 as the next digit of the answer. 
Result so far: 153990.254
Subtracting 2088 from 2500 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 12:
When dividing 4120 by 522, we get 7 with a remainder of 466.
Use 7 as the next digit of our solution. 
Result so far: 153990.2547
If we subtract 3654 from 4120, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Step 13:
4660 divided by 522 is 8 with a remainder of 484.
The next digit of our result is 8. 
Result so far: 153990.25478
The remainder is 484 after subtracting 4176 from 4660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 14:
4840 divided by 522 is 9 with a remainder of 142.
The number 9 becomes the next digit in our result. 
Result so far: 153990.254789
The remainder is 142 after subtracting 4698 from 4840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 15:
The number 522 fits into 1420 2 times, leaving a remainder of 376.
Write down 2 as next digit of the result. 
Result so far: 153990.2547892
If we take 1044 away from 1420, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 16:
The number 522 fits into 3760 7 times, leaving a remainder of 106.
Put 7 as the next digit of the answer. 
Result so far: 153990.25478927
If we take 3654 away from 3760, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Our division results in 153990.25478927 with a remaining 1.06e-07.
