Let's divide 31959391 by 803
Let's see how many times 803 fits into 31959391.

Advancing to step 1:
803 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 803

Going ahead to step 2:
If we divide 31 by 803, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 803

Moving on to step 3:
The number 803 fits into 319 0 times, leaving a remainder of 319.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 319 after subtracting 0 from 319.
Take the next digit (5) from the dividend and append it to 319, then repeat: 3195 / 803

Advancing to step 4:
803 goes into 3195 3 times with a remainder of 786.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 2409 from 3195 to get 786.
Bring next digit (9) of the dividend behind the 786 and repeat the process: 7869 / 803

Step 5:
If we divide 7869 by 803, we get 9 and a remainder of 642.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 7227 from 7869 to get 642.
Fetch the next digit (3) from the dividend, attach it to 642 and continue: 6423 / 803

Moving on to step 6:
803 goes into 6423 7 times with a remainder of 802.
The next digit of our result is 7. 
Result so far: 397.0
Subtract 5621 from 6423 to get 802.
Fetch the next digit (9) from the dividend, attach it to 802 and continue: 8029 / 803

Moving on to step 7:
803 goes into 8029 9 times with a remainder of 802.
Put 9 as the next digit of the answer. 
Result so far: 3979.0
The remainder is 802 after subtracting 7227 from 8029.
Include the next digit (1) from the dividend after 802, then repeat: 8021 / 803

Moving on to step 8:
803 can be fit into 8021 9 times, resulting in a remainder of 794.
Record the quotient 9 as the next digit in the result. 
Result so far: 39799.0
Subtract 7227 from 8021 to get 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Advancing to step 9:
7940 divided by 803 is 9 with a remainder of 713.
Write down 9 as next digit of the result. 
Result so far: 39799.9
Deduct 7227 from 7940 and we're left with 713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

Going ahead to step 10:
803 goes into 7130 8 times with a remainder of 706.
Use 8 as the next digit of our solution. 
Result so far: 39799.98
If we subtract 6424 from 7130, we get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Advancing to step 11:
When dividing 7060 by 803, we get 8 with a remainder of 636.
Put 8 as the next digit of the answer. 
Result so far: 39799.988
Deduct 6424 from 7060 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

In conclusion, the division gives 39799.988 with a balance of 0.0636.
