41512821 divided by 215 
We want to figure out the number of times 41512821 can be divided by 215.

On to step 1:
215 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 215

Step 2:
41 divided by 215 is 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 215

Step 3:
415 divided by 215 is 1 with a remainder of 200.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 215 away from 415, we end up with 200.
Bring next digit (1) of the dividend behind the 200 and repeat the process: 2001 / 215

Let's proceed to step 4:
2001 divided by 215 is 9 with a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 66 after subtracting 1935 from 2001.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 215

Advancing to step 5:
When dividing 662 by 215, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 193.0
If we take 645 away from 662, we end up with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 215

Advancing to step 6:
The number 215 fits into 178 0 times, leaving a remainder of 178.
Put 0 as the next digit of the answer. 
Result so far: 1930.0
Subtracting 0 from 178 leaves us with 178.
Bring next digit (2) of the dividend behind the 178 and repeat the process: 1782 / 215

Going ahead to step 7:
If we divide 1782 by 215, we get 8 and a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 19308.0
If we take 1720 away from 1782, we end up with 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 215

Let's proceed to step 8:
If we divide 621 by 215, we get 2 and a remainder of 191.
Write down 2 as next digit of the result. 
Result so far: 193082.0
Deduct 430 from 621 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 9:
215 can be fit into 1910 8 times, resulting in a remainder of 190.
Use 8 as the next digit of our solution. 
Result so far: 193082.8
Subtract 1720 from 1910 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 10:
The number 215 fits into 1900 8 times, leaving a remainder of 180.
Write down 8 as next digit of the result. 
Result so far: 193082.88
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.

The final result is 193082.88 with a remainder of 0.18.
