We look at the division of 31451 by 99 
We want to figure out the number of times 31451 can be divided by 99.

On to step 1:
If we divide 3 by 99, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 99

On to step 2:
31 divided by 99 is 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 99

Advancing to step 3:
99 goes into 314 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 297 from 314 to get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 99

Moving on to step 4:
If we divide 175 by 99, we get 1 and a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtracting 99 from 175 leaves us with 76.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 99

Let's proceed to step 5:
99 goes into 761 7 times with a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 317.0
The remainder is 68 after subtracting 693 from 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 6:
The number 99 fits into 680 6 times, leaving a remainder of 86.
The next digit of our result is 6. 
Result so far: 317.6
The remainder is 86 after subtracting 594 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 7:
99 goes into 860 8 times with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 317.68
If we take 792 away from 860, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 8:
99 can be fit into 680 6 times, resulting in a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 317.686
Subtract 594 from 680 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 9:
860 divided by 99 is 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 317.6868
Deduct 792 from 860 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
680 divided by 99 is 6 with a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 317.68686
Subtract 594 from 680 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 11:
99 can be fit into 860 8 times, resulting in a remainder of 68.
The next digit of our result is 8. 
Result so far: 317.686868
Deduct 792 from 860 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 12:
If we divide 680 by 99, we get 6 and a remainder of 86.
The next digit of our result is 6. 
Result so far: 317.6868686
If we take 594 away from 680, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 13:
If we divide 860 by 99, we get 8 and a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 317.68686868
Deduct 792 from 860 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 317.68686868 with a balance of 6.8e-08.
