We look at the division of 8614134 by 522 
The aim is to understand the frequency of 522 in 8614134.

On to step 1:
If we divide 8 by 522, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 522

Moving on to step 2:
522 goes into 86 0 times with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 522

Step 3:
522 can be fit into 861 1 times, resulting in a remainder of 339.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 522 from 861 leaves us with 339.
Include the next digit (4) from the dividend after 339, then repeat: 3394 / 522

Going ahead to step 4:
522 goes into 3394 6 times with a remainder of 262.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 3132 from 3394 and we're left with 262.
Append the next digit (1) from the dividend to 262 and continue with: 2621 / 522

Advancing to step 5:
The number 522 fits into 2621 5 times, leaving a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 165.0
Subtract 2610 from 2621 to get 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 522

Step 6:
When dividing 113 by 522, we get 0 with a remainder of 113.
Record the quotient 0 as the next digit in the result. 
Result so far: 1650.0
Subtract 0 from 113 to get 113.
Take the next digit (4) from the dividend and append it to 113, then repeat: 1134 / 522

Going ahead to step 7:
522 goes into 1134 2 times with a remainder of 90.
The next digit of our result is 2. 
Result so far: 16502.0
If we subtract 1044 from 1134, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 8:
900 divided by 522 is 1 with a remainder of 378.
Write down 1 as next digit of the result. 
Result so far: 16502.1
If we subtract 522 from 900, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 9:
522 goes into 3780 7 times with a remainder of 126.
Put 7 as the next digit of the answer. 
Result so far: 16502.17
Subtracting 3654 from 3780 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 10:
522 can be fit into 1260 2 times, resulting in a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 16502.172
Subtracting 1044 from 1260 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 11:
522 goes into 2160 4 times with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 16502.1724
If we subtract 2088 from 2160, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
If we divide 720 by 522, we get 1 and a remainder of 198.
Write down 1 as next digit of the result. 
Result so far: 16502.17241
The remainder is 198 after subtracting 522 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 13:
The number 522 fits into 1980 3 times, leaving a remainder of 414.
The next digit of our result is 3. 
Result so far: 16502.172413
Deduct 1566 from 1980 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 14:
When dividing 4140 by 522, we get 7 with a remainder of 486.
Record the quotient 7 as the next digit in the result. 
Result so far: 16502.1724137
Subtract 3654 from 4140 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 15:
4860 divided by 522 is 9 with a remainder of 162.
Write down 9 as next digit of the result. 
Result so far: 16502.17241379
The remainder is 162 after subtracting 4698 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The final outcome is 16502.17241379, with a leftover of 1.62e-07.
