31159331 divided by 663 
We want to figure out the number of times 31159331 can be divided by 663.

Advancing to step 1:
The number 663 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 663

Step 2:
663 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 663

Moving on to step 3:
311 divided by 663 is 0 with a remainder of 311.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 311, we end up with 311.
Fetch the next digit (5) from the dividend, attach it to 311 and continue: 3115 / 663

Let's proceed to step 4:
663 goes into 3115 4 times with a remainder of 463.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 463 after subtracting 2652 from 3115.
Fetch the next digit (9) from the dividend, attach it to 463 and continue: 4639 / 663

Advancing to step 5:
4639 divided by 663 is 6 with a remainder of 661.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtract 3978 from 4639 to get 661.
Bring next digit (3) of the dividend behind the 661 and repeat the process: 6613 / 663

Step 6:
The number 663 fits into 6613 9 times, leaving a remainder of 646.
Record the quotient 9 as the next digit in the result. 
Result so far: 469.0
If we take 5967 away from 6613, we end up with 646.
Include the next digit (3) from the dividend after 646, then repeat: 6463 / 663

Step 7:
If we divide 6463 by 663, we get 9 and a remainder of 496.
Use 9 as the next digit of our solution. 
Result so far: 4699.0
Subtracting 5967 from 6463 leaves us with 496.
Append the next digit (1) from the dividend to 496 and continue with: 4961 / 663

Step 8:
663 goes into 4961 7 times with a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 46997.0
Deduct 4641 from 4961 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 9:
The number 663 fits into 3200 4 times, leaving a remainder of 548.
The next digit of our result is 4. 
Result so far: 46997.4
The remainder is 548 after subtracting 2652 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 10:
The number 663 fits into 5480 8 times, leaving a remainder of 176.
Use 8 as the next digit of our solution. 
Result so far: 46997.48
The remainder is 176 after subtracting 5304 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 11:
663 can be fit into 1760 2 times, resulting in a remainder of 434.
The next digit of our result is 2. 
Result so far: 46997.482
If we subtract 1326 from 1760, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 12:
The number 663 fits into 4340 6 times, leaving a remainder of 362.
The next digit of our result is 6. 
Result so far: 46997.4826
Subtracting 3978 from 4340 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 13:
If we divide 3620 by 663, we get 5 and a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 46997.48265
Subtracting 3315 from 3620 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 14:
When dividing 3050 by 663, we get 4 with a remainder of 398.
Record the quotient 4 as the next digit in the result. 
Result so far: 46997.482654
Subtract 2652 from 3050 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 15:
When dividing 3980 by 663, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 46997.4826546
Deduct 3978 from 3980 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 16:
The number 663 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 46997.4826546
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 46997.4826546 with a balance of 2e-08.
