We're dividing 52577869 by 215 
We want to figure out the number of times 52577869 can be divided by 215.

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
Subtract 0 from 5 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 215

Advancing to step 2:
When dividing 52 by 215, we get 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 215

Advancing to step 3:
If we divide 525 by 215, we get 2 and a remainder of 95.
The next digit of our result is 2. 
Result so far: 2.0
If we take 430 away from 525, we end up with 95.
Take the next digit (7) from the dividend and append it to 95, then repeat: 957 / 215

On to step 4:
If we divide 957 by 215, we get 4 and a remainder of 97.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 97 after subtracting 860 from 957.
Bring next digit (7) of the dividend behind the 97 and repeat the process: 977 / 215

Going ahead to step 5:
When dividing 977 by 215, we get 4 with a remainder of 117.
Record the quotient 4 as the next digit in the result. 
Result so far: 244.0
Deduct 860 from 977 and we're left with 117.
Include the next digit (8) from the dividend after 117, then repeat: 1178 / 215

Moving on to step 6:
If we divide 1178 by 215, we get 5 and a remainder of 103.
Use 5 as the next digit of our solution. 
Result so far: 2445.0
If we take 1075 away from 1178, we end up with 103.
Fetch the next digit (6) from the dividend, attach it to 103 and continue: 1036 / 215

Going ahead to step 7:
215 can be fit into 1036 4 times, resulting in a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 24454.0
Subtracting 860 from 1036 leaves us with 176.
Grab the next digit (9) from the dividend, add it to 176, then carry on: 1769 / 215

Let's proceed to step 8:
The number 215 fits into 1769 8 times, leaving a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 244548.0
The remainder is 49 after subtracting 1720 from 1769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
215 can be fit into 490 2 times, resulting in a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 244548.2
If we subtract 430 from 490, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
When dividing 600 by 215, we get 2 with a remainder of 170.
Record the quotient 2 as the next digit in the result. 
Result so far: 244548.22
The remainder is 170 after subtracting 430 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 244548.22, with a leftover of 0.17.
