71954609 ÷ 215 
The aim is to understand the frequency of 215 in 71954609.

Moving on to step 1:
215 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 215

Let's proceed to step 2:
When dividing 71 by 215, we get 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 215

Let's proceed to step 3:
If we divide 719 by 215, we get 3 and a remainder of 74.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 645 from 719 leaves us with 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 215

Step 4:
The number 215 fits into 745 3 times, leaving a remainder of 100.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Subtract 645 from 745 to get 100.
Take the next digit (4) from the dividend and append it to 100, then repeat: 1004 / 215

Moving on to step 5:
215 can be fit into 1004 4 times, resulting in a remainder of 144.
Record the quotient 4 as the next digit in the result. 
Result so far: 334.0
Subtract 860 from 1004 to get 144.
Include the next digit (6) from the dividend after 144, then repeat: 1446 / 215

Moving on to step 6:
If we divide 1446 by 215, we get 6 and a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 3346.0
The remainder is 156 after subtracting 1290 from 1446.
Fetch the next digit (0) from the dividend, attach it to 156 and continue: 1560 / 215

On to step 7:
When dividing 1560 by 215, we get 7 with a remainder of 55.
The next digit of our result is 7. 
Result so far: 33467.0
Subtracting 1505 from 1560 leaves us with 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 215

Advancing to step 8:
215 goes into 559 2 times with a remainder of 129.
The next digit of our result is 2. 
Result so far: 334672.0
Subtracting 430 from 559 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 9:
215 goes into 1290 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 334672.6
Subtract 1290 from 1290 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
215 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 334672.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 215 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 334672.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 334672.6 with a balance of 0.0.
