We divide 31245099 by 451
We're looking to find how many times 451 goes into 31245099.

Going ahead to step 1:
451 goes into 3 0 times with 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.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 451

Moving on to step 2:
451 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 451

Let's proceed to step 3:
312 divided by 451 is 0 with a remainder of 312.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 312, we end up with 312.
Take the next digit (4) from the dividend and append it to 312, then repeat: 3124 / 451

Let's proceed to step 4:
3124 divided by 451 is 6 with a remainder of 418.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 2706 from 3124 to get 418.
Bring next digit (5) of the dividend behind the 418 and repeat the process: 4185 / 451

Advancing to step 5:
451 can be fit into 4185 9 times, resulting in a remainder of 126.
The next digit of our result is 9. 
Result so far: 69.0
If we subtract 4059 from 4185, we get 126.
Bring next digit (0) of the dividend behind the 126 and repeat the process: 1260 / 451

Let's proceed to step 6:
451 can be fit into 1260 2 times, resulting in a remainder of 358.
Use 2 as the next digit of our solution. 
Result so far: 692.0
If we subtract 902 from 1260, we get 358.
Bring next digit (9) of the dividend behind the 358 and repeat the process: 3589 / 451

Going ahead to step 7:
451 goes into 3589 7 times with a remainder of 432.
Use 7 as the next digit of our solution. 
Result so far: 6927.0
If we take 3157 away from 3589, we end up with 432.
Include the next digit (9) from the dividend after 432, then repeat: 4329 / 451

Moving on to step 8:
451 goes into 4329 9 times with a remainder of 270.
The number 9 becomes the next digit in our result. 
Result so far: 69279.0
If we subtract 4059 from 4329, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 9:
451 goes into 2700 5 times with a remainder of 445.
The next digit of our result is 5. 
Result so far: 69279.5
The remainder is 445 after subtracting 2255 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 10:
451 can be fit into 4450 9 times, resulting in a remainder of 391.
Use 9 as the next digit of our solution. 
Result so far: 69279.59
Deduct 4059 from 4450 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 11:
If we divide 3910 by 451, we get 8 and a remainder of 302.
Put 8 as the next digit of the answer. 
Result so far: 69279.598
Deduct 3608 from 3910 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 12:
3020 divided by 451 is 6 with a remainder of 314.
The number 6 becomes the next digit in our result. 
Result so far: 69279.5986
Subtracting 2706 from 3020 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 13:
The number 451 fits into 3140 6 times, leaving a remainder of 434.
Use 6 as the next digit of our solution. 
Result so far: 69279.59866
If we take 2706 away from 3140, we end up with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

After the division, we end up with 69279.59866 and a remainder of 0.000434.
