We look at the division of 81448629 by 566 
The aim is to understand the frequency of 566 in 81448629.

Let's proceed to step 1:
566 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 566

Let's proceed to step 2:
566 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (4) from the dividend, add it to 81, then carry on: 814 / 566

Step 3:
566 can be fit into 814 1 times, resulting in a remainder of 248.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 566 from 814 and we're left with 248.
Take the next digit (4) from the dividend and append it to 248, then repeat: 2484 / 566

Advancing to step 4:
If we divide 2484 by 566, we get 4 and a remainder of 220.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 2264 from 2484 leaves us with 220.
Fetch the next digit (8) from the dividend, attach it to 220 and continue: 2208 / 566

Going ahead to step 5:
The number 566 fits into 2208 3 times, leaving a remainder of 510.
The next digit of our result is 3. 
Result so far: 143.0
If we subtract 1698 from 2208, we get 510.
Include the next digit (6) from the dividend after 510, then repeat: 5106 / 566

Moving on to step 6:
If we divide 5106 by 566, we get 9 and a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 1439.0
Subtracting 5094 from 5106 leaves us with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 566

Going ahead to step 7:
122 divided by 566 is 0 with a remainder of 122.
Use 0 as the next digit of our solution. 
Result so far: 14390.0
Subtracting 0 from 122 leaves us with 122.
Fetch the next digit (9) from the dividend, attach it to 122 and continue: 1229 / 566

Moving on to step 8:
The number 566 fits into 1229 2 times, leaving a remainder of 97.
Use 2 as the next digit of our solution. 
Result so far: 143902.0
If we subtract 1132 from 1229, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
566 goes into 970 1 times with a remainder of 404.
Use 1 as the next digit of our solution. 
Result so far: 143902.1
Deduct 566 from 970 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 10:
566 goes into 4040 7 times with a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 143902.17
Deduct 3962 from 4040 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 11:
The number 566 fits into 780 1 times, leaving a remainder of 214.
The next digit of our result is 1. 
Result so far: 143902.171
Deduct 566 from 780 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 12:
2140 divided by 566 is 3 with a remainder of 442.
Use 3 as the next digit of our solution. 
Result so far: 143902.1713
Subtract 1698 from 2140 to get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Step 13:
566 goes into 4420 7 times with a remainder of 458.
Write down 7 as next digit of the result. 
Result so far: 143902.17137
Subtracting 3962 from 4420 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 14:
If we divide 4580 by 566, we get 8 and a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 143902.171378
Deduct 4528 from 4580 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 15:
566 can be fit into 520 0 times, resulting in a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 143902.171378
Subtracting 0 from 520 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 16:
5200 divided by 566 is 9 with a remainder of 106.
Put 9 as the next digit of the answer. 
Result so far: 143902.17137809
The remainder is 106 after subtracting 5094 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The quotient of the division is 143902.17137809, and the remainder is 1.06e-07.
