We divide 663692 by 31
We're looking to find how many times 31 goes into 663692.

Moving on to step 1:
31 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 31

Step 2:
66 divided by 31 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 62 away from 66, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 31

Step 3:
43 divided by 31 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 31 from 43 to get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 31

Let's proceed to step 4:
31 goes into 126 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 214.0
The remainder is 2 after subtracting 124 from 126.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 31

Moving on to step 5:
When dividing 29 by 31, we get 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 2140.0
Deduct 0 from 29 and we're left with 29.
Take the next digit (2) from the dividend and append it to 29, then repeat: 292 / 31

Going ahead to step 6:
31 can be fit into 292 9 times, resulting in a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 21409.0
If we take 279 away from 292, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
31 can be fit into 130 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 21409.4
Deduct 124 from 130 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
60 divided by 31 is 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 21409.41
Subtract 31 from 60 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
If we divide 290 by 31, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 21409.419
Deduct 279 from 290 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
110 divided by 31 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 21409.4193
Subtract 93 from 110 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
170 divided by 31 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 21409.41935
If we subtract 155 from 170, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
150 divided by 31 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 21409.419354
Subtracting 124 from 150 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 13:
If we divide 260 by 31, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 21409.4193548
If we subtract 248 from 260, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
120 divided by 31 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 21409.41935483
If we take 93 away from 120, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 21409.41935483 with a remainder of 2.7e-08.
