We look at the division of 13222050 by 437 
The aim is to understand the frequency of 437 in 13222050.

Let's proceed to step 1:
437 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 437

Going ahead to step 2:
437 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 437

Advancing to step 3:
When dividing 132 by 437, we get 0 with a remainder of 132.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 132, we end up with 132.
Append the next digit (2) from the dividend to 132 and continue with: 1322 / 437

On to step 4:
If we divide 1322 by 437, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 1311 from 1322, we get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 437

On to step 5:
112 divided by 437 is 0 with a remainder of 112.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we take 0 away from 112, we end up with 112.
Fetch the next digit (0) from the dividend, attach it to 112 and continue: 1120 / 437

Step 6:
If we divide 1120 by 437, we get 2 and a remainder of 246.
The number 2 becomes the next digit in our result. 
Result so far: 302.0
Subtract 874 from 1120 to get 246.
Fetch the next digit (5) from the dividend, attach it to 246 and continue: 2465 / 437

Let's proceed to step 7:
2465 divided by 437 is 5 with a remainder of 280.
Put 5 as the next digit of the answer. 
Result so far: 3025.0
Deduct 2185 from 2465 and we're left with 280.
Append the next digit (0) from the dividend to 280 and continue with: 2800 / 437

Going ahead to step 8:
2800 divided by 437 is 6 with a remainder of 178.
Record the quotient 6 as the next digit in the result. 
Result so far: 30256.0
Subtract 2622 from 2800 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 9:
437 goes into 1780 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 30256.4
If we subtract 1748 from 1780, we 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.

Going ahead to step 10:
320 divided by 437 is 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 30256.4
Deduct 0 from 320 and we're left with 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:
3200 divided by 437 is 7 with a remainder of 141.
Record the quotient 7 as the next digit in the result. 
Result so far: 30256.407
If we take 3059 away from 3200, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 12:
437 goes into 1410 3 times with a remainder of 99.
Use 3 as the next digit of our solution. 
Result so far: 30256.4073
If we subtract 1311 from 1410, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 13:
437 goes into 990 2 times with a remainder of 116.
Put 2 as the next digit of the answer. 
Result so far: 30256.40732
Subtract 874 from 990 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 14:
437 can be fit into 1160 2 times, resulting in a remainder of 286.
Write down 2 as next digit of the result. 
Result so far: 30256.407322
The remainder is 286 after subtracting 874 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

The final result is 30256.407322 with a remainder of 2.86e-05.
