We're dividing 31659853 by 409 
Let's see how many times 409 fits into 31659853.

Step 1:
3 divided by 409 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 409

On to step 2:
409 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 409

Going ahead to step 3:
The number 409 fits into 316 0 times, leaving a remainder of 316.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 316 after subtracting 0 from 316.
Append the next digit (5) from the dividend to 316 and continue with: 3165 / 409

Going ahead to step 4:
3165 divided by 409 is 7 with a remainder of 302.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 2863 from 3165, we get 302.
Fetch the next digit (9) from the dividend, attach it to 302 and continue: 3029 / 409

Advancing to step 5:
409 can be fit into 3029 7 times, resulting in a remainder of 166.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we subtract 2863 from 3029, we get 166.
Bring next digit (8) of the dividend behind the 166 and repeat the process: 1668 / 409

Advancing to step 6:
If we divide 1668 by 409, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 774.0
Deduct 1636 from 1668 and we're left with 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 409

Step 7:
If we divide 325 by 409, we get 0 and a remainder of 325.
Record the quotient 0 as the next digit in the result. 
Result so far: 7740.0
If we take 0 away from 325, we end up with 325.
Grab the next digit (3) from the dividend, add it to 325, then carry on: 3253 / 409

Moving on to step 8:
409 goes into 3253 7 times with a remainder of 390.
Write down 7 as next digit of the result. 
Result so far: 77407.0
Deduct 2863 from 3253 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 9:
When dividing 3900 by 409, we get 9 with a remainder of 219.
Put 9 as the next digit of the answer. 
Result so far: 77407.9
The remainder is 219 after subtracting 3681 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 10:
409 can be fit into 2190 5 times, resulting in a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 77407.95
Subtracting 2045 from 2190 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 11:
409 can be fit into 1450 3 times, resulting in a remainder of 223.
The next digit of our result is 3. 
Result so far: 77407.953
If we take 1227 away from 1450, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 12:
409 goes into 2230 5 times with a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 77407.9535
Deduct 2045 from 2230 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 13:
1850 divided by 409 is 4 with a remainder of 214.
The next digit of our result is 4. 
Result so far: 77407.95354
If we take 1636 away from 1850, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 14:
409 can be fit into 2140 5 times, resulting in a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 77407.953545
If we take 2045 away from 2140, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 15:
The number 409 fits into 950 2 times, leaving a remainder of 132.
Write down 2 as next digit of the result. 
Result so far: 77407.9535452
Deduct 818 from 950 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 16:
1320 divided by 409 is 3 with a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 77407.95354523
The remainder is 93 after subtracting 1227 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Our division results in 77407.95354523 with a remaining 9.3e-08.
