We look at the division of 664163 by 31 
We want to divide 664163 by 31.

Step 1:
When dividing 6 by 31, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 31

On to step 2:
When dividing 66 by 31, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 62 from 66, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 31

Going ahead to step 3:
If we divide 44 by 31, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 31 from 44 leaves us with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 31

Step 4:
31 can be fit into 131 4 times, resulting in a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
Subtract 124 from 131 to get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 31

Going ahead to step 5:
If we divide 76 by 31, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 2142.0
If we subtract 62 from 76, we get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 31

Advancing to step 6:
31 goes into 143 4 times with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 21424.0
Subtract 124 from 143 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 31, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 21424.6
Deduct 186 from 190 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
31 can be fit into 40 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 21424.61
If we subtract 31 from 40, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 31, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 21424.612
If we take 62 away from 90, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
When dividing 280 by 31, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 21424.6129
Subtracting 279 from 280 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
10 divided by 31 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 21424.6129
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 21424.612903
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 13:
70 divided by 31 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 21424.6129032
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
If we divide 80 by 31, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 21424.61290322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 21424.61290322 with a balance of 1.8e-08.
