Let's divide 12431145 by 631
Let's see how many times 631 fits into 12431145.

Moving on to step 1:
1 divided by 631 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 631

Let's proceed to step 2:
12 divided by 631 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 631

Moving on to step 3:
124 divided by 631 is 0 with a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Include the next digit (3) from the dividend after 124, then repeat: 1243 / 631

Going ahead to step 4:
When dividing 1243 by 631, we get 1 with a remainder of 612.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 612 after subtracting 631 from 1243.
Grab the next digit (1) from the dividend, add it to 612, then carry on: 6121 / 631

Let's proceed to step 5:
631 can be fit into 6121 9 times, resulting in a remainder of 442.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 5679 from 6121 and we're left with 442.
Append the next digit (1) from the dividend to 442 and continue with: 4421 / 631

On to step 6:
631 goes into 4421 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
If we take 4417 away from 4421, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 631

Moving on to step 7:
The number 631 fits into 44 0 times, leaving a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 1970.0
If we take 0 away from 44, we end up with 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 631

On to step 8:
631 goes into 445 0 times with a remainder of 445.
The next digit of our result is 0. 
Result so far: 19700.0
If we subtract 0 from 445, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 9:
631 can be fit into 4450 7 times, resulting in a remainder of 33.
The next digit of our result is 7. 
Result so far: 19700.7
If we subtract 4417 from 4450, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
If we divide 330 by 631, we get 0 and a remainder of 330.
The next digit of our result is 0. 
Result so far: 19700.7
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 11:
The number 631 fits into 3300 5 times, leaving a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 19700.705
If we subtract 3155 from 3300, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 12:
1450 divided by 631 is 2 with a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 19700.7052
Deduct 1262 from 1450 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 13:
The number 631 fits into 1880 2 times, leaving a remainder of 618.
Record the quotient 2 as the next digit in the result. 
Result so far: 19700.70522
The remainder is 618 after subtracting 1262 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

The final outcome is 19700.70522, with a leftover of 0.000618.
