We look at the division of 83151536 by 409 
Our goal is to divide 83151536 by 409.

Going ahead to step 1:
When dividing 8 by 409, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 409

On to step 2:
The number 409 fits into 83 0 times, leaving a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 409

Going ahead to step 3:
409 can be fit into 831 2 times, resulting in a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
If we take 818 away from 831, we end up with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 409

Step 4:
If we divide 135 by 409, we get 0 and a remainder of 135.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 135, we get 135.
Fetch the next digit (1) from the dividend, attach it to 135 and continue: 1351 / 409

Going ahead to step 5:
409 can be fit into 1351 3 times, resulting in a remainder of 124.
Use 3 as the next digit of our solution. 
Result so far: 203.0
Deduct 1227 from 1351 and we're left with 124.
Take the next digit (5) from the dividend and append it to 124, then repeat: 1245 / 409

Step 6:
409 can be fit into 1245 3 times, resulting in a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 2033.0
If we subtract 1227 from 1245, we get 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 409

Moving on to step 7:
409 can be fit into 183 0 times, resulting in a remainder of 183.
Use 0 as the next digit of our solution. 
Result so far: 20330.0
The remainder is 183 after subtracting 0 from 183.
Bring next digit (6) of the dividend behind the 183 and repeat the process: 1836 / 409

Step 8:
If we divide 1836 by 409, we get 4 and a remainder of 200.
Use 4 as the next digit of our solution. 
Result so far: 203304.0
The remainder is 200 after subtracting 1636 from 1836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 9:
2000 divided by 409 is 4 with a remainder of 364.
Write down 4 as next digit of the result. 
Result so far: 203304.4
If we take 1636 away from 2000, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 10:
The number 409 fits into 3640 8 times, leaving a remainder of 368.
Write down 8 as next digit of the result. 
Result so far: 203304.48
Subtract 3272 from 3640 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 11:
3680 divided by 409 is 8 with a remainder of 408.
Put 8 as the next digit of the answer. 
Result so far: 203304.488
The remainder is 408 after subtracting 3272 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final result is 203304.488 with a remainder of 0.0408.
