We look at the division of 11778890 by 566 
The aim is to understand the frequency of 566 in 11778890.

Advancing to step 1:
566 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 566

Advancing to step 2:
566 can be fit into 11 0 times, resulting in a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 566

Moving on to step 3:
If we divide 117 by 566, we get 0 and a remainder of 117.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 117 and we're left with 117.
Grab the next digit (7) from the dividend, add it to 117, then carry on: 1177 / 566

Let's proceed to step 4:
566 can be fit into 1177 2 times, resulting in a remainder of 45.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1132 from 1177 to get 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 566

Going ahead to step 5:
566 goes into 458 0 times with a remainder of 458.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 458, we end up with 458.
Grab the next digit (8) from the dividend, add it to 458, then carry on: 4588 / 566

Step 6:
566 can be fit into 4588 8 times, resulting in a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 208.0
Subtracting 4528 from 4588 leaves us with 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 566

Step 7:
566 can be fit into 609 1 times, resulting in a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 2081.0
If we subtract 566 from 609, we get 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 566

Moving on to step 8:
566 goes into 430 0 times with a remainder of 430.
Record the quotient 0 as the next digit in the result. 
Result so far: 20810.0
Subtracting 0 from 430 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 9:
If we divide 4300 by 566, we get 7 and a remainder of 338.
Record the quotient 7 as the next digit in the result. 
Result so far: 20810.7
Subtracting 3962 from 4300 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 10:
3380 divided by 566 is 5 with a remainder of 550.
The next digit of our result is 5. 
Result so far: 20810.75
If we subtract 2830 from 3380, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 11:
If we divide 5500 by 566, we get 9 and a remainder of 406.
Put 9 as the next digit of the answer. 
Result so far: 20810.759
Subtract 5094 from 5500 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 12:
The number 566 fits into 4060 7 times, leaving a remainder of 98.
The next digit of our result is 7. 
Result so far: 20810.7597
If we take 3962 away from 4060, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 13:
980 divided by 566 is 1 with a remainder of 414.
The next digit of our result is 1. 
Result so far: 20810.75971
The remainder is 414 after subtracting 566 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 14:
566 can be fit into 4140 7 times, resulting in a remainder of 178.
Write down 7 as next digit of the result. 
Result so far: 20810.759717
If we subtract 3962 from 4140, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 15:
566 goes into 1780 3 times with a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 20810.7597173
Subtracting 1698 from 1780 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 16:
When dividing 820 by 566, we get 1 with a remainder of 254.
Write down 1 as next digit of the result. 
Result so far: 20810.75971731
Deduct 566 from 820 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Our division results in 20810.75971731 with a remaining 2.54e-07.
