31484166 ÷ 315 
We want to divide 31484166 by 315.

Moving on to step 1:
If we divide 3 by 315, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 315

Going ahead to step 2:
The number 315 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 315

Advancing to step 3:
315 goes into 314 0 times with a remainder of 314.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 314, we end up with 314.
Append the next digit (8) from the dividend to 314 and continue with: 3148 / 315

Step 4:
3148 divided by 315 is 9 with a remainder of 313.
The next digit of our result is 9. 
Result so far: 9.0
If we take 2835 away from 3148, we end up with 313.
Include the next digit (4) from the dividend after 313, then repeat: 3134 / 315

Going ahead to step 5:
The number 315 fits into 3134 9 times, leaving a remainder of 299.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtracting 2835 from 3134 leaves us with 299.
Take the next digit (1) from the dividend and append it to 299, then repeat: 2991 / 315

Moving on to step 6:
The number 315 fits into 2991 9 times, leaving a remainder of 156.
Record the quotient 9 as the next digit in the result. 
Result so far: 999.0
Subtracting 2835 from 2991 leaves us with 156.
Bring next digit (6) of the dividend behind the 156 and repeat the process: 1566 / 315

On to step 7:
When dividing 1566 by 315, we get 4 with a remainder of 306.
Put 4 as the next digit of the answer. 
Result so far: 9994.0
If we subtract 1260 from 1566, we get 306.
Fetch the next digit (6) from the dividend, attach it to 306 and continue: 3066 / 315

Advancing to step 8:
3066 divided by 315 is 9 with a remainder of 231.
The number 9 becomes the next digit in our result. 
Result so far: 99949.0
Subtracting 2835 from 3066 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 9:
2310 divided by 315 is 7 with a remainder of 105.
The next digit of our result is 7. 
Result so far: 99949.7
Deduct 2205 from 2310 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 10:
1050 divided by 315 is 3 with a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 99949.73
If we take 945 away from 1050, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 11:
315 can be fit into 1050 3 times, resulting in a remainder of 105.
The next digit of our result is 3. 
Result so far: 99949.733
Deduct 945 from 1050 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

In conclusion, the division gives 99949.733 with a balance of 0.0105.
