Let's divide 89779801 by 566
The aim is to understand the frequency of 566 in 89779801.

Step 1:
When dividing 8 by 566, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 566

On to step 2:
If we divide 89 by 566, we get 0 and a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Fetch the next digit (7) from the dividend, attach it to 89 and continue: 897 / 566

Step 3:
897 divided by 566 is 1 with a remainder of 331.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 566 from 897, we get 331.
Grab the next digit (7) from the dividend, add it to 331, then carry on: 3317 / 566

Let's proceed to step 4:
3317 divided by 566 is 5 with a remainder of 487.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 2830 from 3317, we get 487.
Grab the next digit (9) from the dividend, add it to 487, then carry on: 4879 / 566

Let's proceed to step 5:
566 goes into 4879 8 times with a remainder of 351.
The next digit of our result is 8. 
Result so far: 158.0
The remainder is 351 after subtracting 4528 from 4879.
Bring next digit (8) of the dividend behind the 351 and repeat the process: 3518 / 566

Advancing to step 6:
566 goes into 3518 6 times with a remainder of 122.
Write down 6 as next digit of the result. 
Result so far: 1586.0
Subtract 3396 from 3518 to get 122.
Fetch the next digit (0) from the dividend, attach it to 122 and continue: 1220 / 566

Moving on to step 7:
566 can be fit into 1220 2 times, resulting in a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 15862.0
Subtract 1132 from 1220 to get 88.
Take the next digit (1) from the dividend and append it to 88, then repeat: 881 / 566

Moving on to step 8:
566 goes into 881 1 times with a remainder of 315.
Record the quotient 1 as the next digit in the result. 
Result so far: 158621.0
The remainder is 315 after subtracting 566 from 881.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 9:
When dividing 3150 by 566, we get 5 with a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 158621.5
If we take 2830 away from 3150, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 10:
When dividing 3200 by 566, we get 5 with a remainder of 370.
The next digit of our result is 5. 
Result so far: 158621.55
If we subtract 2830 from 3200, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

After the division, we end up with 158621.55 and a remainder of 0.37.
