We look at the division of 80962764 by 215 
The aim is to understand the frequency of 215 in 80962764.

Advancing to step 1:
215 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 215

On to step 2:
80 divided by 215 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 215

Step 3:
215 can be fit into 809 3 times, resulting in a remainder of 164.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 645 away from 809, we end up with 164.
Include the next digit (6) from the dividend after 164, then repeat: 1646 / 215

On to step 4:
1646 divided by 215 is 7 with a remainder of 141.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 1505 from 1646 and we're left with 141.
Fetch the next digit (2) from the dividend, attach it to 141 and continue: 1412 / 215

On to step 5:
1412 divided by 215 is 6 with a remainder of 122.
The number 6 becomes the next digit in our result. 
Result so far: 376.0
Subtracting 1290 from 1412 leaves us with 122.
Fetch the next digit (7) from the dividend, attach it to 122 and continue: 1227 / 215

Advancing to step 6:
215 goes into 1227 5 times with a remainder of 152.
The next digit of our result is 5. 
Result so far: 3765.0
If we subtract 1075 from 1227, we get 152.
Include the next digit (6) from the dividend after 152, then repeat: 1526 / 215

Let's proceed to step 7:
If we divide 1526 by 215, we get 7 and a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 37657.0
Subtract 1505 from 1526 to get 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 215

Let's proceed to step 8:
215 can be fit into 214 0 times, resulting in a remainder of 214.
Record the quotient 0 as the next digit in the result. 
Result so far: 376570.0
The remainder is 214 after subtracting 0 from 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 9:
When dividing 2140 by 215, we get 9 with a remainder of 205.
Use 9 as the next digit of our solution. 
Result so far: 376570.9
If we subtract 1935 from 2140, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 10:
2050 divided by 215 is 9 with a remainder of 115.
Write down 9 as next digit of the result. 
Result so far: 376570.99
The remainder is 115 after subtracting 1935 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

After the division, we end up with 376570.99 and a remainder of 0.115.
