Let's divide 41992099 by 409
We want to divide 41992099 by 409.

Going ahead to step 1:
When dividing 4 by 409, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 409

Step 2:
41 divided by 409 is 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 409

Let's proceed to step 3:
The number 409 fits into 419 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 409 away from 419, we end up with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 409

Step 4:
When dividing 109 by 409, we get 0 with a remainder of 109.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 109 and we're left with 109.
Grab the next digit (2) from the dividend, add it to 109, then carry on: 1092 / 409

Moving on to step 5:
The number 409 fits into 1092 2 times, leaving a remainder of 274.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Subtract 818 from 1092 to get 274.
Take the next digit (0) from the dividend and append it to 274, then repeat: 2740 / 409

Advancing to step 6:
409 can be fit into 2740 6 times, resulting in a remainder of 286.
Write down 6 as next digit of the result. 
Result so far: 1026.0
Deduct 2454 from 2740 and we're left with 286.
Append the next digit (9) from the dividend to 286 and continue with: 2869 / 409

Let's proceed to step 7:
409 goes into 2869 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 10267.0
Subtracting 2863 from 2869 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 409

Let's proceed to step 8:
409 can be fit into 69 0 times, resulting in a remainder of 69.
The next digit of our result is 0. 
Result so far: 102670.0
If we take 0 away from 69, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 9:
The number 409 fits into 690 1 times, leaving a remainder of 281.
Put 1 as the next digit of the answer. 
Result so far: 102670.1
Deduct 409 from 690 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 10:
If we divide 2810 by 409, we get 6 and a remainder of 356.
Write down 6 as next digit of the result. 
Result so far: 102670.16
The remainder is 356 after subtracting 2454 from 2810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 11:
3560 divided by 409 is 8 with a remainder of 288.
Record the quotient 8 as the next digit in the result. 
Result so far: 102670.168
If we subtract 3272 from 3560, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 12:
2880 divided by 409 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 102670.1687
If we subtract 2863 from 2880, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
When dividing 170 by 409, we get 0 with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 102670.1687
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 14:
If we divide 1700 by 409, we get 4 and a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 102670.168704
Deduct 1636 from 1700 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 15:
640 divided by 409 is 1 with a remainder of 231.
Put 1 as the next digit of the answer. 
Result so far: 102670.1687041
Subtract 409 from 640 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 16:
If we divide 2310 by 409, we get 5 and a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 102670.16870415
Deduct 2045 from 2310 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

The final result is 102670.16870415 with a remainder of 2.65e-07.
