638282 ÷ 31 
We want to divide 638282 by 31.

On to step 1:
31 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 31

Advancing to step 2:
The number 31 fits into 63 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 62 from 63 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 31

Moving on to step 3:
31 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 31

On to step 4:
If we divide 182 by 31, we get 5 and a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
Subtracting 155 from 182 leaves us with 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 31

Advancing to step 5:
278 divided by 31 is 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 2058.0
If we subtract 248 from 278, we get 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 31

Step 6:
31 goes into 302 9 times with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 20589.0
If we subtract 279 from 302, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
31 goes into 230 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 20589.7
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
If we divide 130 by 31, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 20589.74
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.

Moving on to step 9:
When dividing 60 by 31, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 20589.741
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.

Let's proceed to step 10:
290 divided by 31 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 20589.7419
Subtract 279 from 290 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
If we divide 110 by 31, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 20589.74193
The remainder is 17 after subtracting 93 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
31 can be fit into 170 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 20589.741935
Deduct 155 from 170 and we're left with 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 13:
When dividing 150 by 31, we get 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 20589.7419354
If we subtract 124 from 150, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
31 can be fit into 260 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 20589.74193548
Subtract 248 from 260 to 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.

In conclusion, the division gives 20589.74193548 with a balance of 1.2e-08.
