We're dividing 55556765 by 215 
Our goal is to divide 55556765 by 215.

Moving on to step 1:
If we divide 5 by 215, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 215

Advancing to step 2:
215 goes into 55 0 times with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Include the next digit (5) from the dividend after 55, then repeat: 555 / 215

Let's proceed to step 3:
When dividing 555 by 215, we get 2 with a remainder of 125.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 430 from 555 and we're left with 125.
Append the next digit (5) from the dividend to 125 and continue with: 1255 / 215

On to step 4:
1255 divided by 215 is 5 with a remainder of 180.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 1075 from 1255 and we're left with 180.
Take the next digit (6) from the dividend and append it to 180, then repeat: 1806 / 215

Step 5:
215 can be fit into 1806 8 times, resulting in a remainder of 86.
Use 8 as the next digit of our solution. 
Result so far: 258.0
If we take 1720 away from 1806, we end up with 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 215

Moving on to step 6:
867 divided by 215 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 2584.0
If we take 860 away from 867, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 215

Step 7:
215 can be fit into 76 0 times, resulting in a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 25840.0
Subtract 0 from 76 to get 76.
Append the next digit (5) from the dividend to 76 and continue with: 765 / 215

Moving on to step 8:
215 can be fit into 765 3 times, resulting in a remainder of 120.
Use 3 as the next digit of our solution. 
Result so far: 258403.0
The remainder is 120 after subtracting 645 from 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 9:
215 can be fit into 1200 5 times, resulting in a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 258403.5
The remainder is 125 after subtracting 1075 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 10:
If we divide 1250 by 215, we get 5 and a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 258403.55
The remainder is 175 after subtracting 1075 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final outcome is 258403.55, with a leftover of 0.175.
