We look at the division of 8223612 by 612 
The aim is to understand the frequency of 612 in 8223612.

Going ahead to step 1:
The number 612 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 612

On to step 2:
82 divided by 612 is 0 with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Fetch the next digit (2) from the dividend, attach it to 82 and continue: 822 / 612

Step 3:
When dividing 822 by 612, we get 1 with a remainder of 210.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 210 after subtracting 612 from 822.
Fetch the next digit (3) from the dividend, attach it to 210 and continue: 2103 / 612

On to step 4:
612 can be fit into 2103 3 times, resulting in a remainder of 267.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1836 from 2103, we get 267.
Grab the next digit (6) from the dividend, add it to 267, then carry on: 2676 / 612

Step 5:
612 goes into 2676 4 times with a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 134.0
Subtract 2448 from 2676 to get 228.
Include the next digit (1) from the dividend after 228, then repeat: 2281 / 612

Step 6:
612 goes into 2281 3 times with a remainder of 445.
Write down 3 as next digit of the result. 
Result so far: 1343.0
If we subtract 1836 from 2281, we get 445.
Grab the next digit (2) from the dividend, add it to 445, then carry on: 4452 / 612

Advancing to step 7:
When dividing 4452 by 612, we get 7 with a remainder of 168.
The number 7 becomes the next digit in our result. 
Result so far: 13437.0
Subtracting 4284 from 4452 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 8:
If we divide 1680 by 612, we get 2 and a remainder of 456.
Record the quotient 2 as the next digit in the result. 
Result so far: 13437.2
Subtract 1224 from 1680 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 9:
612 goes into 4560 7 times with a remainder of 276.
Record the quotient 7 as the next digit in the result. 
Result so far: 13437.27
Deduct 4284 from 4560 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 10:
612 can be fit into 2760 4 times, resulting in a remainder of 312.
Record the quotient 4 as the next digit in the result. 
Result so far: 13437.274
If we subtract 2448 from 2760, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 11:
612 can be fit into 3120 5 times, resulting in a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 13437.2745
If we take 3060 away from 3120, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
The number 612 fits into 600 0 times, leaving a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 13437.2745
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 13:
When dividing 6000 by 612, we get 9 with a remainder of 492.
Write down 9 as next digit of the result. 
Result so far: 13437.274509
Deduct 5508 from 6000 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Moving on to step 14:
612 goes into 4920 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 13437.2745098
If we take 4896 away from 4920, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 15:
612 can be fit into 240 0 times, resulting in a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 13437.2745098
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The quotient of the division is 13437.2745098, and the remainder is 2.4e-07.
