We look at the division of 31918568 by 802 
We want to divide 31918568 by 802.

Advancing to step 1:
802 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
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 802

Moving on to step 2:
If we divide 31 by 802, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 802

Moving on to step 3:
802 goes into 319 0 times with a remainder of 319.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 319 after subtracting 0 from 319.
Fetch the next digit (1) from the dividend, attach it to 319 and continue: 3191 / 802

On to step 4:
802 goes into 3191 3 times with a remainder of 785.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 785 after subtracting 2406 from 3191.
Bring next digit (8) of the dividend behind the 785 and repeat the process: 7858 / 802

Step 5:
7858 divided by 802 is 9 with a remainder of 640.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtracting 7218 from 7858 leaves us with 640.
Include the next digit (5) from the dividend after 640, then repeat: 6405 / 802

Let's proceed to step 6:
6405 divided by 802 is 7 with a remainder of 791.
Write down 7 as next digit of the result. 
Result so far: 397.0
The remainder is 791 after subtracting 5614 from 6405.
Grab the next digit (6) from the dividend, add it to 791, then carry on: 7916 / 802

Moving on to step 7:
802 goes into 7916 9 times with a remainder of 698.
Write down 9 as next digit of the result. 
Result so far: 3979.0
If we subtract 7218 from 7916, we get 698.
Bring next digit (8) of the dividend behind the 698 and repeat the process: 6988 / 802

Advancing to step 8:
When dividing 6988 by 802, we get 8 with a remainder of 572.
Record the quotient 8 as the next digit in the result. 
Result so far: 39798.0
Subtract 6416 from 6988 to get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Let's proceed to step 9:
802 can be fit into 5720 7 times, resulting in a remainder of 106.
Write down 7 as next digit of the result. 
Result so far: 39798.7
Subtract 5614 from 5720 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 10:
When dividing 1060 by 802, we get 1 with a remainder of 258.
Record the quotient 1 as the next digit in the result. 
Result so far: 39798.71
If we subtract 802 from 1060, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 11:
2580 divided by 802 is 3 with a remainder of 174.
The next digit of our result is 3. 
Result so far: 39798.713
Subtracting 2406 from 2580 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 12:
802 can be fit into 1740 2 times, resulting in a remainder of 136.
Write down 2 as next digit of the result. 
Result so far: 39798.7132
Subtract 1604 from 1740 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 13:
If we divide 1360 by 802, we get 1 and a remainder of 558.
Use 1 as the next digit of our solution. 
Result so far: 39798.71321
Subtract 802 from 1360 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 14:
When dividing 5580 by 802, we get 6 with a remainder of 768.
The next digit of our result is 6. 
Result so far: 39798.713216
Subtracting 4812 from 5580 leaves us with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

On to step 15:
802 goes into 7680 9 times with a remainder of 462.
The next digit of our result is 9. 
Result so far: 39798.7132169
If we subtract 7218 from 7680, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Let's proceed to step 16:
If we divide 4620 by 802, we get 5 and a remainder of 610.
Use 5 as the next digit of our solution. 
Result so far: 39798.71321695
If we take 4010 away from 4620, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

In conclusion, the division gives 39798.71321695 with a balance of 6.1e-07.
