56253662 ÷ 215 
The aim is to understand the frequency of 215 in 56253662.

Let's proceed to step 1:
5 divided by 215 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 215

Going ahead to step 2:
The number 215 fits into 56 0 times, leaving a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Fetch the next digit (2) from the dividend, attach it to 56 and continue: 562 / 215

On to step 3:
215 can be fit into 562 2 times, resulting in a remainder of 132.
The next digit of our result is 2. 
Result so far: 2.0
If we take 430 away from 562, we end up with 132.
Include the next digit (5) from the dividend after 132, then repeat: 1325 / 215

Step 4:
215 goes into 1325 6 times with a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 1290 from 1325 leaves us with 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 215

On to step 5:
If we divide 353 by 215, we get 1 and a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 261.0
If we take 215 away from 353, we end up with 138.
Bring next digit (6) of the dividend behind the 138 and repeat the process: 1386 / 215

Let's proceed to step 6:
When dividing 1386 by 215, we get 6 with a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 2616.0
If we take 1290 away from 1386, we end up with 96.
Include the next digit (6) from the dividend after 96, then repeat: 966 / 215

Moving on to step 7:
The number 215 fits into 966 4 times, leaving a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 26164.0
Subtract 860 from 966 to get 106.
Grab the next digit (2) from the dividend, add it to 106, then carry on: 1062 / 215

Let's proceed to step 8:
215 goes into 1062 4 times with a remainder of 202.
Use 4 as the next digit of our solution. 
Result so far: 261644.0
Subtracting 860 from 1062 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 9:
215 can be fit into 2020 9 times, resulting in a remainder of 85.
Record the quotient 9 as the next digit in the result. 
Result so far: 261644.9
Subtract 1935 from 2020 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
When dividing 850 by 215, we get 3 with a remainder of 205.
The number 3 becomes the next digit in our result. 
Result so far: 261644.93
If we take 645 away from 850, we end up with 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 11:
If we divide 2050 by 215, we get 9 and a remainder of 115.
Record the quotient 9 as the next digit in the result. 
Result so far: 261644.939
If we subtract 1935 from 2050, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 12:
215 can be fit into 1150 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 261644.9395
If we take 1075 away from 1150, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 13:
If we divide 750 by 215, we get 3 and a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 261644.93953
Deduct 645 from 750 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 14:
215 goes into 1050 4 times with a remainder of 190.
Record the quotient 4 as the next digit in the result. 
Result so far: 261644.939534
If we take 860 away from 1050, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 15:
When dividing 1900 by 215, we get 8 with a remainder of 180.
Put 8 as the next digit of the answer. 
Result so far: 261644.9395348
Subtract 1720 from 1900 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 16:
215 goes into 1800 8 times with a remainder of 80.
The next digit of our result is 8. 
Result so far: 261644.93953488
Subtracting 1720 from 1800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 261644.93953488 with a remainder of 8e-08.
