We want to divide 31389659 by 638.

Let's proceed to step 1:
638 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 638

Going ahead to step 2:
31 divided by 638 is 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 638

Going ahead to step 3:
The number 638 fits into 313 0 times, leaving a remainder of 313.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 313 after subtracting 0 from 313.
Take the next digit (8) from the dividend and append it to 313, then repeat: 3138 / 638

Step 4:
3138 divided by 638 is 4 with a remainder of 586.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 2552 from 3138 leaves us with 586.
Grab the next digit (9) from the dividend, add it to 586, then carry on: 5869 / 638

Moving on to step 5:
5869 divided by 638 is 9 with a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we take 5742 away from 5869, we end up with 127.
Grab the next digit (6) from the dividend, add it to 127, then carry on: 1276 / 638

Step 6:
When dividing 1276 by 638, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 492.0
Deduct 1276 from 1276 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 638

Going ahead to step 7:
5 divided by 638 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 4920.0
If we subtract 0 from 5, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 638

Let's proceed to step 8:
If we divide 59 by 638, we get 0 and a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 49200.0
The remainder is 59 after subtracting 0 from 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
638 goes into 590 0 times with a remainder of 590.
Put 0 as the next digit of the answer. 
Result so far: 49200.0
Subtracting 0 from 590 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 10:
638 goes into 5900 9 times with a remainder of 158.
Use 9 as the next digit of our solution. 
Result so far: 49200.09
If we take 5742 away from 5900, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 11:
638 can be fit into 1580 2 times, resulting in a remainder of 304.
Use 2 as the next digit of our solution. 
Result so far: 49200.092
If we subtract 1276 from 1580, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 12:
638 can be fit into 3040 4 times, resulting in a remainder of 488.
The number 4 becomes the next digit in our result. 
Result so far: 49200.0924
Subtract 2552 from 3040 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 13:
The number 638 fits into 4880 7 times, leaving a remainder of 414.
Put 7 as the next digit of the answer. 
Result so far: 49200.09247
Subtracting 4466 from 4880 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 14:
If we divide 4140 by 638, we get 6 and a remainder of 312.
Use 6 as the next digit of our solution. 
Result so far: 49200.092476
If we subtract 3828 from 4140, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 15:
The number 638 fits into 3120 4 times, leaving a remainder of 568.
The next digit of our result is 4. 
Result so far: 49200.0924764
Deduct 2552 from 3120 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Let's proceed to step 16:
If we divide 5680 by 638, we get 8 and a remainder of 576.
Use 8 as the next digit of our solution. 
Result so far: 49200.09247648
The remainder is 576 after subtracting 5104 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

In conclusion, the division gives 49200.09247648 with a balance of 5.76e-07.
