96512639 divided by 631 
Our goal is to divide 96512639 by 631.

On to step 1:
The number 631 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 631

Let's proceed to step 2:
When dividing 96 by 631, we get 0 with a remainder of 96.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 96 to get 96.
Bring next digit (5) of the dividend behind the 96 and repeat the process: 965 / 631

Step 3:
631 can be fit into 965 1 times, resulting in a remainder of 334.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 631 from 965 to get 334.
Take the next digit (1) from the dividend and append it to 334, then repeat: 3341 / 631

Moving on to step 4:
631 goes into 3341 5 times with a remainder of 186.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 3155 away from 3341, we end up with 186.
Append the next digit (2) from the dividend to 186 and continue with: 1862 / 631

Moving on to step 5:
If we divide 1862 by 631, we get 2 and a remainder of 600.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
Subtracting 1262 from 1862 leaves us with 600.
Append the next digit (6) from the dividend to 600 and continue with: 6006 / 631

Moving on to step 6:
631 can be fit into 6006 9 times, resulting in a remainder of 327.
Put 9 as the next digit of the answer. 
Result so far: 1529.0
Subtract 5679 from 6006 to get 327.
Include the next digit (3) from the dividend after 327, then repeat: 3273 / 631

Moving on to step 7:
631 can be fit into 3273 5 times, resulting in a remainder of 118.
The next digit of our result is 5. 
Result so far: 15295.0
The remainder is 118 after subtracting 3155 from 3273.
Fetch the next digit (9) from the dividend, attach it to 118 and continue: 1189 / 631

Going ahead to step 8:
631 can be fit into 1189 1 times, resulting in a remainder of 558.
The next digit of our result is 1. 
Result so far: 152951.0
Deduct 631 from 1189 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 9:
The number 631 fits into 5580 8 times, leaving a remainder of 532.
Put 8 as the next digit of the answer. 
Result so far: 152951.8
Subtract 5048 from 5580 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 10:
The number 631 fits into 5320 8 times, leaving a remainder of 272.
Use 8 as the next digit of our solution. 
Result so far: 152951.88
The remainder is 272 after subtracting 5048 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

In conclusion, the division gives 152951.88 with a balance of 0.272.
