We look at the division of 55502140 by 215 
Let's see how many times 215 fits into 55502140.

Advancing to step 1:
When dividing 5 by 215, we get 0 with 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.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 215

On to step 2:
If we divide 55 by 215, we get 0 and a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Append the next digit (5) from the dividend to 55 and continue with: 555 / 215

Moving on to step 3:
215 can be fit into 555 2 times, resulting in a remainder of 125.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 430 from 555 leaves us with 125.
Fetch the next digit (0) from the dividend, attach it to 125 and continue: 1250 / 215

Going ahead to step 4:
When dividing 1250 by 215, we get 5 with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 175 after subtracting 1075 from 1250.
Fetch the next digit (2) from the dividend, attach it to 175 and continue: 1752 / 215

Step 5:
The number 215 fits into 1752 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 258.0
Subtracting 1720 from 1752 leaves us with 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 215

On to step 6:
The number 215 fits into 321 1 times, leaving a remainder of 106.
The number 1 becomes the next digit in our result. 
Result so far: 2581.0
If we take 215 away from 321, we end up with 106.
Bring next digit (4) of the dividend behind the 106 and repeat the process: 1064 / 215

On to step 7:
When dividing 1064 by 215, we get 4 with a remainder of 204.
The next digit of our result is 4. 
Result so far: 25814.0
Subtract 860 from 1064 to get 204.
Include the next digit (0) from the dividend after 204, then repeat: 2040 / 215

Moving on to step 8:
215 goes into 2040 9 times with a remainder of 105.
The next digit of our result is 9. 
Result so far: 258149.0
If we take 1935 away from 2040, we end up 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.

Going ahead to step 9:
215 can be fit into 1050 4 times, resulting in a remainder of 190.
Use 4 as the next digit of our solution. 
Result so far: 258149.4
Subtracting 860 from 1050 leaves us 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 10:
1900 divided by 215 is 8 with a remainder of 180.
Record the quotient 8 as the next digit in the result. 
Result so far: 258149.48
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.

Step 11:
1800 divided by 215 is 8 with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 258149.488
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 outcome is 258149.488, with a leftover of 0.008.
