Going ahead to step 1:
The number 631 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 631

Advancing to step 2:
If we divide 10 by 631, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 631

Going ahead to step 3:
103 divided by 631 is 0 with a remainder of 103.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 103 to get 103.
Fetch the next digit (9) from the dividend, attach it to 103 and continue: 1039 / 631

Let's proceed to step 4:
If we divide 1039 by 631, we get 1 and a remainder of 408.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 631 away from 1039, we end up with 408.
Fetch the next digit (8) from the dividend, attach it to 408 and continue: 4088 / 631

Moving on to step 5:
4088 divided by 631 is 6 with a remainder of 302.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 3786 from 4088, we get 302.
Take the next digit (9) from the dividend and append it to 302, then repeat: 3029 / 631

Going ahead to step 6:
The number 631 fits into 3029 4 times, leaving a remainder of 505.
The next digit of our result is 4. 
Result so far: 164.0
The remainder is 505 after subtracting 2524 from 3029.
Append the next digit (6) from the dividend to 505 and continue with: 5056 / 631

Going ahead to step 7:
631 goes into 5056 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 1648.0
Subtract 5048 from 5056 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 631

On to step 8:
89 divided by 631 is 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 16480.0
Subtracting 0 from 89 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 9:
890 divided by 631 is 1 with a remainder of 259.
Write down 1 as next digit of the result. 
Result so far: 16480.1
The remainder is 259 after subtracting 631 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 10:
The number 631 fits into 2590 4 times, leaving a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 16480.14
The remainder is 66 after subtracting 2524 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
The number 631 fits into 660 1 times, leaving a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 16480.141
The remainder is 29 after subtracting 631 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
290 divided by 631 is 0 with a remainder of 290.
Use 0 as the next digit of our solution. 
Result so far: 16480.141
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 13:
631 can be fit into 2900 4 times, resulting in a remainder of 376.
Write down 4 as next digit of the result. 
Result so far: 16480.14104
If we subtract 2524 from 2900, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 14:
The number 631 fits into 3760 5 times, leaving a remainder of 605.
Record the quotient 5 as the next digit in the result. 
Result so far: 16480.141045
Subtract 3155 from 3760 to get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

On to step 15:
When dividing 6050 by 631, we get 9 with a remainder of 371.
Write down 9 as next digit of the result. 
Result so far: 16480.1410459
If we take 5679 away from 6050, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

On to step 16:
631 can be fit into 3710 5 times, resulting in a remainder of 555.
The next digit of our result is 5. 
Result so far: 16480.14104595
Deduct 3155 from 3710 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

The final outcome is 16480.14104595, with a leftover of 5.55e-07.
