We divide 216378 by 55
The aim is to understand the frequency of 55 in 216378.

On to step 1:
55 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 55

Going ahead to step 2:
If we divide 21 by 55, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 55

On to step 3:
55 goes into 216 3 times with a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 165 from 216 leaves us with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 55

Step 4:
513 divided by 55 is 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 18 after subtracting 495 from 513.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 55

Step 5:
55 goes into 187 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 393.0
If we take 165 away from 187, we end up with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 55

Let's proceed to step 6:
When dividing 228 by 55, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 3934.0
If we subtract 220 from 228, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
If we divide 80 by 55, we get 1 and a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 3934.1
If we take 55 away from 80, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
250 divided by 55 is 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 3934.14
If we subtract 220 from 250, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
If we divide 300 by 55, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 3934.145
If we subtract 275 from 300, 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 10:
The number 55 fits into 250 4 times, leaving a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 3934.1454
If we subtract 220 from 250, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
The number 55 fits into 300 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 3934.14545
If we subtract 275 from 300, 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.

Moving on to step 12:
55 goes into 250 4 times with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 3934.145454
If we take 220 away from 250, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
If we divide 300 by 55, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 3934.1454545
Subtract 275 from 300 to 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.

On to step 14:
55 can be fit into 250 4 times, resulting in a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 3934.14545454
If we take 220 away from 250, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 3934.14545454 and a remainder of 3e-08.
