We divide 18140860 by 31
Let's see how many times 31 fits into 18140860.

Going ahead to step 1:
1 divided by 31 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 31

Moving on to step 2:
The number 31 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 31

Going ahead to step 3:
The number 31 fits into 181 5 times, leaving a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 26 after subtracting 155 from 181.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 31

Advancing to step 4:
If we divide 264 by 31, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 58.0
Subtracting 248 from 264 leaves us with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 31

On to step 5:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 585.0
Deduct 155 from 160 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 31

Let's proceed to step 6:
When dividing 58 by 31, we get 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 5851.0
Deduct 31 from 58 and we're left with 27.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 31

Let's proceed to step 7:
31 goes into 276 8 times with a remainder of 28.
The next digit of our result is 8. 
Result so far: 58518.0
Subtract 248 from 276 to get 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 31

Let's proceed to step 8:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 585189.0
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
The number 31 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 585189.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
The number 31 fits into 100 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 585189.03
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
If we divide 70 by 31, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 585189.032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
If we divide 80 by 31, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 585189.0322
Subtracting 62 from 80 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 585189.0322 with a balance of 0.00018.
