We're dividing 89664645 by 566 
The aim is to understand the frequency of 566 in 89664645.

Let's proceed to step 1:
The number 566 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 566

Going ahead to step 2:
566 can be fit into 89 0 times, resulting in a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Fetch the next digit (6) from the dividend, attach it to 89 and continue: 896 / 566

Let's proceed to step 3:
566 goes into 896 1 times with a remainder of 330.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 566 from 896 to get 330.
Grab the next digit (6) from the dividend, add it to 330, then carry on: 3306 / 566

Let's proceed to step 4:
3306 divided by 566 is 5 with a remainder of 476.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 2830 away from 3306, we end up with 476.
Include the next digit (4) from the dividend after 476, then repeat: 4764 / 566

Going ahead to step 5:
The number 566 fits into 4764 8 times, leaving a remainder of 236.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
The remainder is 236 after subtracting 4528 from 4764.
Grab the next digit (6) from the dividend, add it to 236, then carry on: 2366 / 566

Advancing to step 6:
If we divide 2366 by 566, we get 4 and a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 1584.0
If we subtract 2264 from 2366, we get 102.
Append the next digit (4) from the dividend to 102 and continue with: 1024 / 566

Step 7:
If we divide 1024 by 566, we get 1 and a remainder of 458.
Record the quotient 1 as the next digit in the result. 
Result so far: 15841.0
Deduct 566 from 1024 and we're left with 458.
Take the next digit (5) from the dividend and append it to 458, then repeat: 4585 / 566

Advancing to step 8:
566 goes into 4585 8 times with a remainder of 57.
Record the quotient 8 as the next digit in the result. 
Result so far: 158418.0
Subtract 4528 from 4585 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
570 divided by 566 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 158418.1
Subtracting 566 from 570 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
40 divided by 566 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 158418.1
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
If we divide 400 by 566, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 158418.1
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 158418.1, and the remainder is 0.04.
