We look at the division of 32209908 by 215 
The aim is to understand the frequency of 215 in 32209908.

Advancing to step 1:
The number 215 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 215

Going ahead to step 2:
215 can be fit into 32 0 times, resulting in a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 32, we end up with 32.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 215

Step 3:
If we divide 322 by 215, we get 1 and a remainder of 107.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 215 from 322 and we're left with 107.
Include the next digit (0) from the dividend after 107, then repeat: 1070 / 215

Advancing to step 4:
1070 divided by 215 is 4 with a remainder of 210.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 860 from 1070 to get 210.
Append the next digit (9) from the dividend to 210 and continue with: 2109 / 215

Let's proceed to step 5:
215 can be fit into 2109 9 times, resulting in a remainder of 174.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
The remainder is 174 after subtracting 1935 from 2109.
Bring next digit (9) of the dividend behind the 174 and repeat the process: 1749 / 215

Moving on to step 6:
1749 divided by 215 is 8 with a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 1498.0
If we subtract 1720 from 1749, we get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 215

Let's proceed to step 7:
290 divided by 215 is 1 with a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 14981.0
If we subtract 215 from 290, we get 75.
Fetch the next digit (8) from the dividend, attach it to 75 and continue: 758 / 215

Step 8:
If we divide 758 by 215, we get 3 and a remainder of 113.
Use 3 as the next digit of our solution. 
Result so far: 149813.0
If we take 645 away from 758, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 9:
1130 divided by 215 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 149813.5
Subtract 1075 from 1130 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
550 divided by 215 is 2 with a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 149813.52
If we take 430 away from 550, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
If we divide 1200 by 215, we get 5 and a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 149813.525
If we subtract 1075 from 1200, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 12:
215 can be fit into 1250 5 times, resulting in a remainder of 175.
The next digit of our result is 5. 
Result so far: 149813.5255
If we subtract 1075 from 1250, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Our division results in 149813.5255 with a remaining 0.00175.
