31649340 ÷ 409 
We're looking to find how many times 409 goes into 31649340.

Going ahead to step 1:
If we divide 3 by 409, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 409

Moving on to step 2:
31 divided by 409 is 0 with 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.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 409

On to step 3:
316 divided by 409 is 0 with a remainder of 316.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 316, we end up with 316.
Grab the next digit (4) from the dividend, add it to 316, then carry on: 3164 / 409

Let's proceed to step 4:
When dividing 3164 by 409, we get 7 with a remainder of 301.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 2863 from 3164 leaves us with 301.
Take the next digit (9) from the dividend and append it to 301, then repeat: 3019 / 409

Step 5:
When dividing 3019 by 409, we get 7 with a remainder of 156.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Deduct 2863 from 3019 and we're left with 156.
Grab the next digit (3) from the dividend, add it to 156, then carry on: 1563 / 409

Let's proceed to step 6:
409 goes into 1563 3 times with a remainder of 336.
Write down 3 as next digit of the result. 
Result so far: 773.0
The remainder is 336 after subtracting 1227 from 1563.
Append the next digit (4) from the dividend to 336 and continue with: 3364 / 409

Advancing to step 7:
3364 divided by 409 is 8 with a remainder of 92.
Record the quotient 8 as the next digit in the result. 
Result so far: 7738.0
If we take 3272 away from 3364, we end up with 92.
Fetch the next digit (0) from the dividend, attach it to 92 and continue: 920 / 409

Moving on to step 8:
If we divide 920 by 409, we get 2 and a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 77382.0
If we take 818 away from 920, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 9:
1020 divided by 409 is 2 with a remainder of 202.
The next digit of our result is 2. 
Result so far: 77382.2
Deduct 818 from 1020 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 10:
409 goes into 2020 4 times with a remainder of 384.
Use 4 as the next digit of our solution. 
Result so far: 77382.24
If we take 1636 away from 2020, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 11:
409 can be fit into 3840 9 times, resulting in a remainder of 159.
Write down 9 as next digit of the result. 
Result so far: 77382.249
If we take 3681 away from 3840, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 12:
409 can be fit into 1590 3 times, resulting in a remainder of 363.
Record the quotient 3 as the next digit in the result. 
Result so far: 77382.2493
If we take 1227 away from 1590, we end up with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 13:
If we divide 3630 by 409, we get 8 and a remainder of 358.
Put 8 as the next digit of the answer. 
Result so far: 77382.24938
Deduct 3272 from 3630 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 14:
3580 divided by 409 is 8 with a remainder of 308.
The next digit of our result is 8. 
Result so far: 77382.249388
Subtracting 3272 from 3580 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Our division results in 77382.249388 with a remaining 3.08e-05.
