We're dividing 31555206 by 638 
We want to figure out the number of times 31555206 can be divided by 638.

Going ahead to step 1:
If we divide 3 by 638, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 638

Moving on to step 2:
638 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 638

Going ahead to step 3:
638 can be fit into 315 0 times, resulting in a remainder of 315.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 315 to get 315.
Take the next digit (5) from the dividend and append it to 315, then repeat: 3155 / 638

On to step 4:
3155 divided by 638 is 4 with a remainder of 603.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 2552 away from 3155, we end up with 603.
Append the next digit (5) from the dividend to 603 and continue with: 6035 / 638

Going ahead to step 5:
638 goes into 6035 9 times with a remainder of 293.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 5742 away from 6035, we end up with 293.
Include the next digit (2) from the dividend after 293, then repeat: 2932 / 638

Advancing to step 6:
638 can be fit into 2932 4 times, resulting in a remainder of 380.
The next digit of our result is 4. 
Result so far: 494.0
Deduct 2552 from 2932 and we're left with 380.
Bring next digit (0) of the dividend behind the 380 and repeat the process: 3800 / 638

Advancing to step 7:
638 can be fit into 3800 5 times, resulting in a remainder of 610.
The next digit of our result is 5. 
Result so far: 4945.0
If we subtract 3190 from 3800, we get 610.
Append the next digit (6) from the dividend to 610 and continue with: 6106 / 638

Let's proceed to step 8:
When dividing 6106 by 638, we get 9 with a remainder of 364.
The number 9 becomes the next digit in our result. 
Result so far: 49459.0
If we subtract 5742 from 6106, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 9:
When dividing 3640 by 638, we get 5 with a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 49459.5
Subtract 3190 from 3640 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 10:
The number 638 fits into 4500 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 49459.57
If we take 4466 away from 4500, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
638 goes into 340 0 times with a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 49459.57
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 12:
When dividing 3400 by 638, we get 5 with a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 49459.5705
Subtract 3190 from 3400 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 13:
If we divide 2100 by 638, we get 3 and a remainder of 186.
Put 3 as the next digit of the answer. 
Result so far: 49459.57053
If we take 1914 away from 2100, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 14:
When dividing 1860 by 638, we get 2 with a remainder of 584.
Record the quotient 2 as the next digit in the result. 
Result so far: 49459.570532
Subtracting 1276 from 1860 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Moving on to step 15:
If we divide 5840 by 638, we get 9 and a remainder of 98.
Record the quotient 9 as the next digit in the result. 
Result so far: 49459.5705329
Subtract 5742 from 5840 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 16:
The number 638 fits into 980 1 times, leaving a remainder of 342.
Write down 1 as next digit of the result. 
Result so far: 49459.57053291
Deduct 638 from 980 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

In conclusion, the division gives 49459.57053291 with a balance of 3.42e-07.
