80688000 divided by 522 
The aim is to understand the frequency of 522 in 80688000.

Let's proceed to step 1:
522 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 522

Let's proceed 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
Subtract 0 from 80 to get 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 522

Step 3:
When dividing 806 by 522, we get 1 with a remainder of 284.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 522 from 806 leaves us with 284.
Grab the next digit (8) from the dividend, add it to 284, then carry on: 2848 / 522

Moving on to step 4:
When dividing 2848 by 522, we get 5 with a remainder of 238.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 2610 from 2848 and we're left with 238.
Fetch the next digit (8) from the dividend, attach it to 238 and continue: 2388 / 522

Going ahead to step 5:
If we divide 2388 by 522, we get 4 and a remainder of 300.
Use 4 as the next digit of our solution. 
Result so far: 154.0
Subtract 2088 from 2388 to get 300.
Include the next digit (0) from the dividend after 300, then repeat: 3000 / 522

On to step 6:
522 can be fit into 3000 5 times, resulting in a remainder of 390.
Put 5 as the next digit of the answer. 
Result so far: 1545.0
Subtracting 2610 from 3000 leaves us with 390.
Append the next digit (0) from the dividend to 390 and continue with: 3900 / 522

On to step 7:
The number 522 fits into 3900 7 times, leaving a remainder of 246.
The next digit of our result is 7. 
Result so far: 15457.0
The remainder is 246 after subtracting 3654 from 3900.
Append the next digit (0) from the dividend to 246 and continue with: 2460 / 522

Moving on to step 8:
The number 522 fits into 2460 4 times, leaving a remainder of 372.
Write down 4 as next digit of the result. 
Result so far: 154574.0
Deduct 2088 from 2460 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 9:
When dividing 3720 by 522, we get 7 with a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 154574.7
Deduct 3654 from 3720 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
If we divide 660 by 522, we get 1 and a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 154574.71
Subtracting 522 from 660 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 11:
The number 522 fits into 1380 2 times, leaving a remainder of 336.
Use 2 as the next digit of our solution. 
Result so far: 154574.712
If we subtract 1044 from 1380, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 12:
If we divide 3360 by 522, we get 6 and a remainder of 228.
Put 6 as the next digit of the answer. 
Result so far: 154574.7126
Subtract 3132 from 3360 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 13:
When dividing 2280 by 522, we get 4 with a remainder of 192.
The number 4 becomes the next digit in our result. 
Result so far: 154574.71264
Deduct 2088 from 2280 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 14:
If we divide 1920 by 522, we get 3 and a remainder of 354.
Use 3 as the next digit of our solution. 
Result so far: 154574.712643
If we subtract 1566 from 1920, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 15:
If we divide 3540 by 522, we get 6 and a remainder of 408.
The number 6 becomes the next digit in our result. 
Result so far: 154574.7126436
Deduct 3132 from 3540 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 16:
If we divide 4080 by 522, we get 7 and a remainder of 426.
Write down 7 as next digit of the result. 
Result so far: 154574.71264367
Subtract 3654 from 4080 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

The final result is 154574.71264367 with a remainder of 4.26e-07.
