We want to divide 31973287 by 649.

On to step 1:
3 divided by 649 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 649

Step 2:
The number 649 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 649

Going ahead to step 3:
319 divided by 649 is 0 with a remainder of 319.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 319 and we're left with 319.
Append the next digit (7) from the dividend to 319 and continue with: 3197 / 649

Step 4:
649 goes into 3197 4 times with a remainder of 601.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 2596 from 3197 leaves us with 601.
Append the next digit (3) from the dividend to 601 and continue with: 6013 / 649

Step 5:
649 can be fit into 6013 9 times, resulting in a remainder of 172.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we take 5841 away from 6013, we end up with 172.
Take the next digit (2) from the dividend and append it to 172, then repeat: 1722 / 649

Step 6:
When dividing 1722 by 649, we get 2 with a remainder of 424.
Write down 2 as next digit of the result. 
Result so far: 492.0
The remainder is 424 after subtracting 1298 from 1722.
Include the next digit (8) from the dividend after 424, then repeat: 4248 / 649

Going ahead to step 7:
4248 divided by 649 is 6 with a remainder of 354.
The next digit of our result is 6. 
Result so far: 4926.0
If we take 3894 away from 4248, we end up with 354.
Fetch the next digit (7) from the dividend, attach it to 354 and continue: 3547 / 649

Moving on to step 8:
3547 divided by 649 is 5 with a remainder of 302.
Write down 5 as next digit of the result. 
Result so far: 49265.0
The remainder is 302 after subtracting 3245 from 3547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 9:
649 goes into 3020 4 times with a remainder of 424.
The number 4 becomes the next digit in our result. 
Result so far: 49265.4
If we subtract 2596 from 3020, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 10:
The number 649 fits into 4240 6 times, leaving a remainder of 346.
Write down 6 as next digit of the result. 
Result so far: 49265.46
Subtracting 3894 from 4240 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 11:
When dividing 3460 by 649, we get 5 with a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 49265.465
Deduct 3245 from 3460 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 12:
649 can be fit into 2150 3 times, resulting in a remainder of 203.
Record the quotient 3 as the next digit in the result. 
Result so far: 49265.4653
Deduct 1947 from 2150 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Step 13:
When dividing 2030 by 649, we get 3 with a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 49265.46533
Subtract 1947 from 2030 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

In conclusion, the division gives 49265.46533 with a balance of 8.3e-05.
