We're dividing 31558610 by 809 
We want to divide 31558610 by 809.

Going ahead to step 1:
3 divided by 809 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 809

Moving on to step 2:
The number 809 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 809

Let's proceed to step 3:
When dividing 315 by 809, we get 0 with a remainder of 315.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 315 to get 315.
Grab the next digit (5) from the dividend, add it to 315, then carry on: 3155 / 809

Let's proceed to step 4:
3155 divided by 809 is 3 with a remainder of 728.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 2427 from 3155 and we're left with 728.
Bring next digit (8) of the dividend behind the 728 and repeat the process: 7288 / 809

Advancing to step 5:
When dividing 7288 by 809, we get 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 7281 from 7288, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 809

Moving on to step 6:
If we divide 76 by 809, we get 0 and a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 390.0
Subtracting 0 from 76 leaves us with 76.
Bring next digit (1) of the dividend behind the 76 and repeat the process: 761 / 809

Moving on to step 7:
If we divide 761 by 809, we get 0 and a remainder of 761.
The number 0 becomes the next digit in our result. 
Result so far: 3900.0
The remainder is 761 after subtracting 0 from 761.
Bring next digit (0) of the dividend behind the 761 and repeat the process: 7610 / 809

Advancing to step 8:
7610 divided by 809 is 9 with a remainder of 329.
Put 9 as the next digit of the answer. 
Result so far: 39009.0
Deduct 7281 from 7610 and we're left with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

On to step 9:
If we divide 3290 by 809, we get 4 and a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 39009.4
Subtract 3236 from 3290 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
809 goes into 540 0 times with a remainder of 540.
The number 0 becomes the next digit in our result. 
Result so far: 39009.4
Subtract 0 from 540 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 11:
5400 divided by 809 is 6 with a remainder of 546.
Put 6 as the next digit of the answer. 
Result so far: 39009.406
If we take 4854 away from 5400, we end up with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

On to step 12:
The number 809 fits into 5460 6 times, leaving a remainder of 606.
The next digit of our result is 6. 
Result so far: 39009.4066
Deduct 4854 from 5460 and we're left with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

The final result is 39009.4066 with a remainder of 0.00606.
