We're dividing 524367 by 45 
The aim is to understand the frequency of 45 in 524367.

Step 1:
If we divide 5 by 45, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 45

Moving on to step 2:
When dividing 52 by 45, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 52 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 45

On to step 3:
45 goes into 74 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 45 from 74 and we're left with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 45

Step 4:
If we divide 293 by 45, we get 6 and a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Deduct 270 from 293 and we're left with 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 45

On to step 5:
If we divide 236 by 45, we get 5 and a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 1165.0
Subtracting 225 from 236 leaves us with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 45

Let's proceed to step 6:
117 divided by 45 is 2 with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 11652.0
If we take 90 away from 117, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
If we divide 270 by 45, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 11652.6
The remainder is 0 after subtracting 270 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 45, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11652.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 45 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11652.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 11652.6 with a remaining 0.0.
