We're dividing 31296928 by 409 
Let's see how many times 409 fits into 31296928.

Advancing to step 1:
When dividing 3 by 409, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 409

Going ahead to step 2:
409 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 409

Let's proceed to step 3:
When dividing 312 by 409, we get 0 with a remainder of 312.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 312, we get 312.
Grab the next digit (9) from the dividend, add it to 312, then carry on: 3129 / 409

Step 4:
409 can be fit into 3129 7 times, resulting in a remainder of 266.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 2863 from 3129 leaves us with 266.
Take the next digit (6) from the dividend and append it to 266, then repeat: 2666 / 409

Going ahead to step 5:
The number 409 fits into 2666 6 times, leaving a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 76.0
Deduct 2454 from 2666 and we're left with 212.
Bring next digit (9) of the dividend behind the 212 and repeat the process: 2129 / 409

On to step 6:
The number 409 fits into 2129 5 times, leaving a remainder of 84.
The number 5 becomes the next digit in our result. 
Result so far: 765.0
Deduct 2045 from 2129 and we're left with 84.
Take the next digit (2) from the dividend and append it to 84, then repeat: 842 / 409

Let's proceed to step 7:
409 goes into 842 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 7652.0
If we subtract 818 from 842, we get 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 409

Moving on to step 8:
If we divide 248 by 409, we get 0 and a remainder of 248.
The number 0 becomes the next digit in our result. 
Result so far: 76520.0
The remainder is 248 after subtracting 0 from 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 9:
The number 409 fits into 2480 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 76520.6
Subtracting 2454 from 2480 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
When dividing 260 by 409, we get 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 76520.6
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
409 goes into 2600 6 times with a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 76520.606
Subtracting 2454 from 2600 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 12:
The number 409 fits into 1460 3 times, leaving a remainder of 233.
Write down 3 as next digit of the result. 
Result so far: 76520.6063
If we subtract 1227 from 1460, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 13:
The number 409 fits into 2330 5 times, leaving a remainder of 285.
The number 5 becomes the next digit in our result. 
Result so far: 76520.60635
Subtracting 2045 from 2330 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 14:
When dividing 2850 by 409, we get 6 with a remainder of 396.
Use 6 as the next digit of our solution. 
Result so far: 76520.606356
The remainder is 396 after subtracting 2454 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 15:
409 goes into 3960 9 times with a remainder of 279.
Use 9 as the next digit of our solution. 
Result so far: 76520.6063569
The remainder is 279 after subtracting 3681 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 16:
2790 divided by 409 is 6 with a remainder of 336.
Use 6 as the next digit of our solution. 
Result so far: 76520.60635696
The remainder is 336 after subtracting 2454 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final result is 76520.60635696 with a remainder of 3.36e-07.
