We're dividing 64539167 by 443 
The aim is to understand the frequency of 443 in 64539167.

Moving on to step 1:
When dividing 6 by 443, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 443

Let's proceed to step 2:
443 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 443

Going ahead to step 3:
443 can be fit into 645 1 times, resulting in a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 443 away from 645, we end up with 202.
Include the next digit (3) from the dividend after 202, then repeat: 2023 / 443

Step 4:
443 goes into 2023 4 times with a remainder of 251.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 1772 from 2023 leaves us with 251.
Grab the next digit (9) from the dividend, add it to 251, then carry on: 2519 / 443

On to step 5:
When dividing 2519 by 443, we get 5 with a remainder of 304.
The next digit of our result is 5. 
Result so far: 145.0
The remainder is 304 after subtracting 2215 from 2519.
Grab the next digit (1) from the dividend, add it to 304, then carry on: 3041 / 443

Let's proceed to step 6:
When dividing 3041 by 443, we get 6 with a remainder of 383.
Write down 6 as next digit of the result. 
Result so far: 1456.0
Subtracting 2658 from 3041 leaves us with 383.
Bring next digit (6) of the dividend behind the 383 and repeat the process: 3836 / 443

Moving on to step 7:
If we divide 3836 by 443, we get 8 and a remainder of 292.
The next digit of our result is 8. 
Result so far: 14568.0
Subtracting 3544 from 3836 leaves us with 292.
Append the next digit (7) from the dividend to 292 and continue with: 2927 / 443

Let's proceed to step 8:
2927 divided by 443 is 6 with a remainder of 269.
The number 6 becomes the next digit in our result. 
Result so far: 145686.0
Deduct 2658 from 2927 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Going ahead to step 9:
2690 divided by 443 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 145686.6
Subtract 2658 from 2690 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
443 goes into 320 0 times with a remainder of 320.
The next digit of our result is 0. 
Result so far: 145686.6
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 11:
If we divide 3200 by 443, we get 7 and a remainder of 99.
Write down 7 as next digit of the result. 
Result so far: 145686.607
Deduct 3101 from 3200 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 12:
If we divide 990 by 443, we get 2 and a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 145686.6072
Subtracting 886 from 990 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 13:
1040 divided by 443 is 2 with a remainder of 154.
Write down 2 as next digit of the result. 
Result so far: 145686.60722
Subtracting 886 from 1040 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final result is 145686.60722 with a remainder of 0.000154.
