Let's divide 409980 by 41
We want to figure out the number of times 409980 can be divided by 41.

On to step 1:
The number 41 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 41

Moving on to step 2:
When dividing 40 by 41, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 41

On to step 3:
409 divided by 41 is 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 369 away from 409, we end up with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 41

Step 4:
When dividing 409 by 41, we get 9 with a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Deduct 369 from 409 and we're left with 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 41

Going ahead to step 5:
When dividing 408 by 41, we get 9 with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 999.0
Subtract 369 from 408 to get 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 41

Step 6:
390 divided by 41 is 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 9999.0
Subtracting 369 from 390 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
41 can be fit into 210 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9999.5
Deduct 205 from 210 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
If we divide 50 by 41, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 9999.51
If we subtract 41 from 50, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
41 goes into 90 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 9999.512
The remainder is 8 after subtracting 82 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
41 goes into 80 1 times with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 9999.5121
Deduct 41 from 80 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 11:
41 can be fit into 390 9 times, resulting in a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 9999.51219
If we subtract 369 from 390, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 12:
41 can be fit into 210 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 9999.512195
If we subtract 205 from 210, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
If we divide 50 by 41, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 9999.5121951
If we subtract 41 from 50, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
If we divide 90 by 41, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 9999.51219512
If we take 82 away from 90, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 9999.51219512 with a remaining 8e-09.
