We divide 527564 by 45
The aim is to understand the frequency of 45 in 527564.

Going ahead to step 1:
If we divide 5 by 45, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 45

Moving on to step 2:
52 divided by 45 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 45 from 52 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 45

Step 3:
The number 45 fits into 77 1 times, leaving a remainder of 32.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 32 after subtracting 45 from 77.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 45

Let's proceed to step 4:
When dividing 325 by 45, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Deduct 315 from 325 and we're left with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 45

Advancing to step 5:
When dividing 106 by 45, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1172.0
If we subtract 90 from 106, we get 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 45

Going ahead to step 6:
The number 45 fits into 164 3 times, leaving a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 11723.0
The remainder is 29 after subtracting 135 from 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
290 divided by 45 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 11723.6
Subtract 270 from 290 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
When dividing 200 by 45, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 11723.64
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 11723.644
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 11723.644 and a remainder of 0.002.
