We look at the division of 43226448 by 214 
The aim is to understand the frequency of 214 in 43226448.

On to step 1:
If we divide 4 by 214, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 214

Let's proceed to step 2:
When dividing 43 by 214, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 214

Advancing to step 3:
432 divided by 214 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 428 from 432 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 214

Moving on to step 4:
214 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 42 to get 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 214

Moving on to step 5:
214 goes into 426 1 times with a remainder of 212.
Put 1 as the next digit of the answer. 
Result so far: 201.0
Subtract 214 from 426 to get 212.
Append the next digit (4) from the dividend to 212 and continue with: 2124 / 214

Advancing to step 6:
214 goes into 2124 9 times with a remainder of 198.
Use 9 as the next digit of our solution. 
Result so far: 2019.0
The remainder is 198 after subtracting 1926 from 2124.
Fetch the next digit (4) from the dividend, attach it to 198 and continue: 1984 / 214

Moving on to step 7:
214 goes into 1984 9 times with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 20199.0
If we take 1926 away from 1984, we end up with 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 214

On to step 8:
214 goes into 588 2 times with a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 201992.0
Subtract 428 from 588 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 9:
214 can be fit into 1600 7 times, resulting in a remainder of 102.
Write down 7 as next digit of the result. 
Result so far: 201992.7
Deduct 1498 from 1600 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
1020 divided by 214 is 4 with a remainder of 164.
The number 4 becomes the next digit in our result. 
Result so far: 201992.74
The remainder is 164 after subtracting 856 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 11:
214 can be fit into 1640 7 times, resulting in a remainder of 142.
Record the quotient 7 as the next digit in the result. 
Result so far: 201992.747
Subtract 1498 from 1640 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 12:
The number 214 fits into 1420 6 times, leaving a remainder of 136.
The next digit of our result is 6. 
Result so far: 201992.7476
Subtracting 1284 from 1420 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 13:
1360 divided by 214 is 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 201992.74766
The remainder is 76 after subtracting 1284 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 201992.74766 and a remainder of 7.6e-05.
