64051 divided by 45 
The aim is to understand the frequency of 45 in 64051.

Advancing to step 1:
45 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 45

Let's proceed to step 2:
64 divided by 45 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 45 from 64 leaves us with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 45

Let's proceed to step 3:
190 divided by 45 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 180 from 190 leaves us with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 45

Step 4:
45 can be fit into 105 2 times, resulting in a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
Subtract 90 from 105 to get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 45

Advancing to step 5:
When dividing 151 by 45, we get 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 1423.0
The remainder is 16 after subtracting 135 from 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 6:
45 can be fit into 160 3 times, resulting in a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 1423.3
Deduct 135 from 160 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
When dividing 250 by 45, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1423.35
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
If we divide 250 by 45, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 1423.355
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 1423.355 and a remainder of 0.0025.
