We divide 566814 by 45
The aim is to understand the frequency of 45 in 566814.

Advancing to step 1:
When dividing 5 by 45, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 45

Step 2:
When dividing 56 by 45, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 45 from 56 to get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 45

Moving on to step 3:
When dividing 116 by 45, we get 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 90 from 116 and we're left with 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 45

Step 4:
If we divide 268 by 45, we get 5 and a remainder of 43.
The next digit of our result is 5. 
Result so far: 125.0
If we subtract 225 from 268, we get 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 45

On to step 5:
If we divide 431 by 45, we get 9 and a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 1259.0
If we take 405 away from 431, we end up with 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 45

Going ahead to step 6:
When dividing 264 by 45, we get 5 with a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 12595.0
If we take 225 away from 264, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
When dividing 390 by 45, we get 8 with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 12595.8
Subtract 360 from 390 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 45, we get 6 and a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 12595.86
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
When dividing 300 by 45, we get 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 12595.866
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 12595.866 with a remainder of 0.003.
