We're dividing 65212831 by 443 
The aim is to understand the frequency of 443 in 65212831.

Going ahead to step 1:
The number 443 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 443

Going ahead to step 2:
When dividing 65 by 443, we get 0 with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 443

Step 3:
443 goes into 652 1 times with a remainder of 209.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 443 away from 652, we end up with 209.
Include the next digit (1) from the dividend after 209, then repeat: 2091 / 443

Advancing to step 4:
When dividing 2091 by 443, we get 4 with a remainder of 319.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 319 after subtracting 1772 from 2091.
Bring next digit (2) of the dividend behind the 319 and repeat the process: 3192 / 443

Advancing to step 5:
3192 divided by 443 is 7 with a remainder of 91.
Use 7 as the next digit of our solution. 
Result so far: 147.0
If we take 3101 away from 3192, we end up with 91.
Grab the next digit (8) from the dividend, add it to 91, then carry on: 918 / 443

Let's proceed to step 6:
443 goes into 918 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 1472.0
If we take 886 away from 918, we end up with 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 443

Let's proceed to step 7:
The number 443 fits into 323 0 times, leaving a remainder of 323.
The next digit of our result is 0. 
Result so far: 14720.0
Subtracting 0 from 323 leaves us with 323.
Grab the next digit (1) from the dividend, add it to 323, then carry on: 3231 / 443

Moving on to step 8:
The number 443 fits into 3231 7 times, leaving a remainder of 130.
Use 7 as the next digit of our solution. 
Result so far: 147207.0
Subtract 3101 from 3231 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 9:
When dividing 1300 by 443, we get 2 with a remainder of 414.
Write down 2 as next digit of the result. 
Result so far: 147207.2
Subtracting 886 from 1300 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 10:
The number 443 fits into 4140 9 times, leaving a remainder of 153.
Use 9 as the next digit of our solution. 
Result so far: 147207.29
Subtracting 3987 from 4140 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 11:
1530 divided by 443 is 3 with a remainder of 201.
Record the quotient 3 as the next digit in the result. 
Result so far: 147207.293
Deduct 1329 from 1530 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 12:
443 goes into 2010 4 times with a remainder of 238.
The number 4 becomes the next digit in our result. 
Result so far: 147207.2934
The remainder is 238 after subtracting 1772 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 13:
2380 divided by 443 is 5 with a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 147207.29345
If we subtract 2215 from 2380, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 14:
443 can be fit into 1650 3 times, resulting in a remainder of 321.
The next digit of our result is 3. 
Result so far: 147207.293453
Deduct 1329 from 1650 and we're left with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Going ahead to step 15:
443 can be fit into 3210 7 times, resulting in a remainder of 109.
Put 7 as the next digit of the answer. 
Result so far: 147207.2934537
Deduct 3101 from 3210 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 16:
When dividing 1090 by 443, we get 2 with a remainder of 204.
The number 2 becomes the next digit in our result. 
Result so far: 147207.29345372
Deduct 886 from 1090 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

In conclusion, the division gives 147207.29345372 with a balance of 2.04e-07.
