55772662 divided by 217 
The aim is to understand the frequency of 217 in 55772662.

Let's proceed to step 1:
The number 217 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 217

Moving on to step 2:
If we divide 55 by 217, we get 0 and a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 217

On to step 3:
The number 217 fits into 557 2 times, leaving a remainder of 123.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 123 after subtracting 434 from 557.
Include the next digit (7) from the dividend after 123, then repeat: 1237 / 217

Let's proceed to step 4:
When dividing 1237 by 217, we get 5 with a remainder of 152.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 1085 from 1237, we get 152.
Bring next digit (2) of the dividend behind the 152 and repeat the process: 1522 / 217

Advancing to step 5:
If we divide 1522 by 217, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 257.0
If we take 1519 away from 1522, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 217

On to step 6:
The number 217 fits into 36 0 times, leaving a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 2570.0
Subtract 0 from 36 to get 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 217

Moving on to step 7:
The number 217 fits into 366 1 times, leaving a remainder of 149.
Put 1 as the next digit of the answer. 
Result so far: 25701.0
The remainder is 149 after subtracting 217 from 366.
Include the next digit (2) from the dividend after 149, then repeat: 1492 / 217

Moving on to step 8:
217 goes into 1492 6 times with a remainder of 190.
The number 6 becomes the next digit in our result. 
Result so far: 257016.0
The remainder is 190 after subtracting 1302 from 1492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 9:
217 can be fit into 1900 8 times, resulting in a remainder of 164.
Record the quotient 8 as the next digit in the result. 
Result so far: 257016.8
Deduct 1736 from 1900 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 10:
When dividing 1640 by 217, we get 7 with a remainder of 121.
Write down 7 as next digit of the result. 
Result so far: 257016.87
Deduct 1519 from 1640 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 11:
217 can be fit into 1210 5 times, resulting in a remainder of 125.
The next digit of our result is 5. 
Result so far: 257016.875
The remainder is 125 after subtracting 1085 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 12:
If we divide 1250 by 217, we get 5 and a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 257016.8755
If we take 1085 away from 1250, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final outcome is 257016.8755, with a leftover of 0.00165.
