We look at the division of 25672172 by 443 
The aim is to understand the frequency of 443 in 25672172.

Going ahead to step 1:
If we divide 2 by 443, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 443

Let's proceed to step 2:
If we divide 25 by 443, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 443

On to step 3:
The number 443 fits into 256 0 times, leaving a remainder of 256.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 256, we end up with 256.
Include the next digit (7) from the dividend after 256, then repeat: 2567 / 443

On to step 4:
If we divide 2567 by 443, we get 5 and a remainder of 352.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 2215 from 2567, we get 352.
Fetch the next digit (2) from the dividend, attach it to 352 and continue: 3522 / 443

Moving on to step 5:
The number 443 fits into 3522 7 times, leaving a remainder of 421.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Subtract 3101 from 3522 to get 421.
Append the next digit (1) from the dividend to 421 and continue with: 4211 / 443

Going ahead to step 6:
When dividing 4211 by 443, we get 9 with a remainder of 224.
The next digit of our result is 9. 
Result so far: 579.0
Deduct 3987 from 4211 and we're left with 224.
Take the next digit (7) from the dividend and append it to 224, then repeat: 2247 / 443

Let's proceed to step 7:
443 goes into 2247 5 times with a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 5795.0
If we take 2215 away from 2247, we end up with 32.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 443

Going ahead to step 8:
443 can be fit into 322 0 times, resulting in a remainder of 322.
The next digit of our result is 0. 
Result so far: 57950.0
Subtract 0 from 322 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 9:
443 goes into 3220 7 times with a remainder of 119.
Use 7 as the next digit of our solution. 
Result so far: 57950.7
The remainder is 119 after subtracting 3101 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 10:
443 goes into 1190 2 times with a remainder of 304.
Record the quotient 2 as the next digit in the result. 
Result so far: 57950.72
Subtracting 886 from 1190 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 11:
If we divide 3040 by 443, we get 6 and a remainder of 382.
Record the quotient 6 as the next digit in the result. 
Result so far: 57950.726
The remainder is 382 after subtracting 2658 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 12:
If we divide 3820 by 443, we get 8 and a remainder of 276.
The next digit of our result is 8. 
Result so far: 57950.7268
The remainder is 276 after subtracting 3544 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 13:
2760 divided by 443 is 6 with a remainder of 102.
Record the quotient 6 as the next digit in the result. 
Result so far: 57950.72686
Subtract 2658 from 2760 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 14:
443 goes into 1020 2 times with a remainder of 134.
Put 2 as the next digit of the answer. 
Result so far: 57950.726862
If we take 886 away from 1020, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 15:
1340 divided by 443 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 57950.7268623
The remainder is 11 after subtracting 1329 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 16:
110 divided by 443 is 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 57950.7268623
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final result is 57950.7268623 with a remainder of 1.1e-07.
