We look at the division of 70292541 by 215 
The aim is to understand the frequency of 215 in 70292541.

Moving on to step 1:
7 divided by 215 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 215

Step 2:
If we divide 70 by 215, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 215

Step 3:
The number 215 fits into 702 3 times, leaving a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 645 from 702 to get 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 215

On to step 4:
When dividing 579 by 215, we get 2 with a remainder of 149.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we take 430 away from 579, we end up with 149.
Fetch the next digit (2) from the dividend, attach it to 149 and continue: 1492 / 215

Advancing to step 5:
If we divide 1492 by 215, we get 6 and a remainder of 202.
The number 6 becomes the next digit in our result. 
Result so far: 326.0
The remainder is 202 after subtracting 1290 from 1492.
Include the next digit (5) from the dividend after 202, then repeat: 2025 / 215

Moving on to step 6:
2025 divided by 215 is 9 with a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 3269.0
Subtracting 1935 from 2025 leaves us with 90.
Take the next digit (4) from the dividend and append it to 90, then repeat: 904 / 215

On to step 7:
If we divide 904 by 215, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 32694.0
If we take 860 away from 904, we end up with 44.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 215

Let's proceed to step 8:
The number 215 fits into 441 2 times, leaving a remainder of 11.
The next digit of our result is 2. 
Result so far: 326942.0
Subtract 430 from 441 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
When dividing 110 by 215, we get 0 with a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 326942.0
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
When dividing 1100 by 215, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 326942.05
If we subtract 1075 from 1100, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
250 divided by 215 is 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 326942.051
If we subtract 215 from 250, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
350 divided by 215 is 1 with a remainder of 135.
Write down 1 as next digit of the result. 
Result so far: 326942.0511
The remainder is 135 after subtracting 215 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Our division results in 326942.0511 with a remaining 0.00135.
