We're dividing 31232770 by 809 
We want to divide 31232770 by 809.

Moving on to step 1:
When dividing 3 by 809, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 809

Going ahead to step 2:
31 divided by 809 is 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 809

On to step 3:
When dividing 312 by 809, 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 take 0 away from 312, we end up with 312.
Fetch the next digit (3) from the dividend, attach it to 312 and continue: 3123 / 809

Step 4:
809 goes into 3123 3 times with a remainder of 696.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 2427 from 3123 leaves us with 696.
Grab the next digit (2) from the dividend, add it to 696, then carry on: 6962 / 809

Let's proceed to step 5:
If we divide 6962 by 809, we get 8 and a remainder of 490.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 6472 from 6962 to get 490.
Fetch the next digit (7) from the dividend, attach it to 490 and continue: 4907 / 809

Moving on to step 6:
The number 809 fits into 4907 6 times, leaving a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 386.0
If we take 4854 away from 4907, we end up with 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 809

On to step 7:
When dividing 537 by 809, we get 0 with a remainder of 537.
Put 0 as the next digit of the answer. 
Result so far: 3860.0
Subtract 0 from 537 to get 537.
Take the next digit (0) from the dividend and append it to 537, then repeat: 5370 / 809

On to step 8:
If we divide 5370 by 809, we get 6 and a remainder of 516.
The next digit of our result is 6. 
Result so far: 38606.0
Subtract 4854 from 5370 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 9:
5160 divided by 809 is 6 with a remainder of 306.
Use 6 as the next digit of our solution. 
Result so far: 38606.6
The remainder is 306 after subtracting 4854 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 10:
When dividing 3060 by 809, we get 3 with a remainder of 633.
Record the quotient 3 as the next digit in the result. 
Result so far: 38606.63
Deduct 2427 from 3060 and we're left with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Let's proceed to step 11:
6330 divided by 809 is 7 with a remainder of 667.
The next digit of our result is 7. 
Result so far: 38606.637
If we subtract 5663 from 6330, we get 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Going ahead to step 12:
809 can be fit into 6670 8 times, resulting in a remainder of 198.
Put 8 as the next digit of the answer. 
Result so far: 38606.6378
Deduct 6472 from 6670 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 13:
The number 809 fits into 1980 2 times, leaving a remainder of 362.
The number 2 becomes the next digit in our result. 
Result so far: 38606.63782
Deduct 1618 from 1980 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 14:
If we divide 3620 by 809, we get 4 and a remainder of 384.
Write down 4 as next digit of the result. 
Result so far: 38606.637824
The remainder is 384 after subtracting 3236 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 15:
3840 divided by 809 is 4 with a remainder of 604.
Write down 4 as next digit of the result. 
Result so far: 38606.6378244
Deduct 3236 from 3840 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

The final result is 38606.6378244 with a remainder of 6.04e-06.
