We look at the division of 12315193 by 566 
The aim is to understand the frequency of 566 in 12315193.

Moving on to step 1:
566 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 566

Step 2:
12 divided by 566 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 566

Advancing to step 3:
The number 566 fits into 123 0 times, leaving a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 123, we get 123.
Fetch the next digit (1) from the dividend, attach it to 123 and continue: 1231 / 566

Moving on to step 4:
566 can be fit into 1231 2 times, resulting in a remainder of 99.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1132 from 1231 leaves us with 99.
Append the next digit (5) from the dividend to 99 and continue with: 995 / 566

Let's proceed to step 5:
The number 566 fits into 995 1 times, leaving a remainder of 429.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 566 from 995 to get 429.
Fetch the next digit (1) from the dividend, attach it to 429 and continue: 4291 / 566

Advancing to step 6:
When dividing 4291 by 566, we get 7 with a remainder of 329.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
If we take 3962 away from 4291, we end up with 329.
Include the next digit (9) from the dividend after 329, then repeat: 3299 / 566

Step 7:
3299 divided by 566 is 5 with a remainder of 469.
Write down 5 as next digit of the result. 
Result so far: 2175.0
Subtract 2830 from 3299 to get 469.
Grab the next digit (3) from the dividend, add it to 469, then carry on: 4693 / 566

Advancing to step 8:
When dividing 4693 by 566, we get 8 with a remainder of 165.
Put 8 as the next digit of the answer. 
Result so far: 21758.0
If we subtract 4528 from 4693, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 9:
When dividing 1650 by 566, we get 2 with a remainder of 518.
Write down 2 as next digit of the result. 
Result so far: 21758.2
Subtracting 1132 from 1650 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Moving on to step 10:
566 goes into 5180 9 times with a remainder of 86.
Use 9 as the next digit of our solution. 
Result so far: 21758.29
Deduct 5094 from 5180 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
860 divided by 566 is 1 with a remainder of 294.
Record the quotient 1 as the next digit in the result. 
Result so far: 21758.291
Subtracting 566 from 860 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 12:
The number 566 fits into 2940 5 times, leaving a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 21758.2915
The remainder is 110 after subtracting 2830 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 13:
The number 566 fits into 1100 1 times, leaving a remainder of 534.
Use 1 as the next digit of our solution. 
Result so far: 21758.29151
If we subtract 566 from 1100, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Let's proceed to step 14:
5340 divided by 566 is 9 with a remainder of 246.
Write down 9 as next digit of the result. 
Result so far: 21758.291519
If we subtract 5094 from 5340, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 15:
When dividing 2460 by 566, we get 4 with a remainder of 196.
The next digit of our result is 4. 
Result so far: 21758.2915194
Subtract 2264 from 2460 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 16:
566 can be fit into 1960 3 times, resulting in a remainder of 262.
The number 3 becomes the next digit in our result. 
Result so far: 21758.29151943
The remainder is 262 after subtracting 1698 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

The final result is 21758.29151943 with a remainder of 2.62e-07.
