We look at the division of 10415527 by 443 
The aim is to understand the frequency of 443 in 10415527.

Let's proceed to step 1:
The number 443 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 443

On to step 2:
443 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 443

Let's proceed to step 3:
443 goes into 104 0 times with a remainder of 104.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 104 to get 104.
Grab the next digit (1) from the dividend, add it to 104, then carry on: 1041 / 443

Let's proceed to step 4:
1041 divided by 443 is 2 with a remainder of 155.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 886 from 1041, we get 155.
Take the next digit (5) from the dividend and append it to 155, then repeat: 1555 / 443

Moving on to step 5:
443 can be fit into 1555 3 times, resulting in a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 1329 from 1555 leaves us with 226.
Append the next digit (5) from the dividend to 226 and continue with: 2265 / 443

Advancing to step 6:
2265 divided by 443 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 235.0
Subtract 2215 from 2265 to get 50.
Grab the next digit (2) from the dividend, add it to 50, then carry on: 502 / 443

Advancing to step 7:
443 goes into 502 1 times with a remainder of 59.
The next digit of our result is 1. 
Result so far: 2351.0
Subtracting 443 from 502 leaves us with 59.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 443

Step 8:
When dividing 597 by 443, we get 1 with a remainder of 154.
Use 1 as the next digit of our solution. 
Result so far: 23511.0
If we subtract 443 from 597, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 9:
If we divide 1540 by 443, we get 3 and a remainder of 211.
The next digit of our result is 3. 
Result so far: 23511.3
If we subtract 1329 from 1540, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 10:
2110 divided by 443 is 4 with a remainder of 338.
The number 4 becomes the next digit in our result. 
Result so far: 23511.34
Subtracting 1772 from 2110 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 11:
443 can be fit into 3380 7 times, resulting in a remainder of 279.
Put 7 as the next digit of the answer. 
Result so far: 23511.347
The remainder is 279 after subtracting 3101 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 12:
When dividing 2790 by 443, we get 6 with a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 23511.3476
Subtracting 2658 from 2790 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 13:
When dividing 1320 by 443, we get 2 with a remainder of 434.
The number 2 becomes the next digit in our result. 
Result so far: 23511.34762
The remainder is 434 after subtracting 886 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Going ahead to step 14:
If we divide 4340 by 443, we get 9 and a remainder of 353.
The number 9 becomes the next digit in our result. 
Result so far: 23511.347629
If we subtract 3987 from 4340, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Step 15:
When dividing 3530 by 443, we get 7 with a remainder of 429.
Write down 7 as next digit of the result. 
Result so far: 23511.3476297
Subtract 3101 from 3530 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Advancing to step 16:
The number 443 fits into 4290 9 times, leaving a remainder of 303.
Write down 9 as next digit of the result. 
Result so far: 23511.34762979
The remainder is 303 after subtracting 3987 from 4290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

The final result is 23511.34762979 with a remainder of 3.03e-07.
