We look at the division of 41220157 by 215 
The aim is to understand the frequency of 215 in 41220157.

Moving on to step 1:
4 divided by 215 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 215

Advancing to step 2:
41 divided by 215 is 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Include the next digit (2) from the dividend after 41, then repeat: 412 / 215

Going ahead to step 3:
215 goes into 412 1 times with a remainder of 197.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 215 from 412 leaves us with 197.
Take the next digit (2) from the dividend and append it to 197, then repeat: 1972 / 215

Moving on to step 4:
If we divide 1972 by 215, we get 9 and a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 1935 away from 1972, we end up with 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 215

Moving on to step 5:
The number 215 fits into 370 1 times, leaving a remainder of 155.
Record the quotient 1 as the next digit in the result. 
Result so far: 191.0
Subtracting 215 from 370 leaves us with 155.
Grab the next digit (1) from the dividend, add it to 155, then carry on: 1551 / 215

Let's proceed to step 6:
215 goes into 1551 7 times with a remainder of 46.
The next digit of our result is 7. 
Result so far: 1917.0
If we subtract 1505 from 1551, we get 46.
Append the next digit (5) from the dividend to 46 and continue with: 465 / 215

Advancing to step 7:
If we divide 465 by 215, we get 2 and a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 19172.0
The remainder is 35 after subtracting 430 from 465.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 215

Step 8:
357 divided by 215 is 1 with a remainder of 142.
The number 1 becomes the next digit in our result. 
Result so far: 191721.0
Subtract 215 from 357 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.

Going ahead to step 9:
If we divide 1420 by 215, we get 6 and a remainder of 130.
The next digit of our result is 6. 
Result so far: 191721.6
Deduct 1290 from 1420 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 10:
When dividing 1300 by 215, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 191721.66
If we subtract 1290 from 1300, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 191721.66, and the remainder is 0.01.
