27055235 ÷ 638 
Let's see how many times 638 fits into 27055235.

Step 1:
When dividing 2 by 638, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 638

Step 2:
638 can be fit into 27 0 times, resulting in a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 638

Moving on to step 3:
The number 638 fits into 270 0 times, leaving a remainder of 270.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 270, we end up with 270.
Fetch the next digit (5) from the dividend, attach it to 270 and continue: 2705 / 638

Let's proceed to step 4:
638 goes into 2705 4 times with a remainder of 153.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 2552 from 2705 and we're left with 153.
Take the next digit (5) from the dividend and append it to 153, then repeat: 1535 / 638

Advancing to step 5:
If we divide 1535 by 638, we get 2 and a remainder of 259.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 1276 from 1535 leaves us with 259.
Fetch the next digit (2) from the dividend, attach it to 259 and continue: 2592 / 638

Let's proceed to step 6:
2592 divided by 638 is 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 424.0
If we take 2552 away from 2592, we end up with 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 638

Advancing to step 7:
When dividing 403 by 638, we get 0 with a remainder of 403.
Record the quotient 0 as the next digit in the result. 
Result so far: 4240.0
The remainder is 403 after subtracting 0 from 403.
Take the next digit (5) from the dividend and append it to 403, then repeat: 4035 / 638

Going ahead to step 8:
If we divide 4035 by 638, we get 6 and a remainder of 207.
Put 6 as the next digit of the answer. 
Result so far: 42406.0
Subtracting 3828 from 4035 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 9:
When dividing 2070 by 638, we get 3 with a remainder of 156.
Write down 3 as next digit of the result. 
Result so far: 42406.3
The remainder is 156 after subtracting 1914 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 10:
When dividing 1560 by 638, we get 2 with a remainder of 284.
The number 2 becomes the next digit in our result. 
Result so far: 42406.32
Subtracting 1276 from 1560 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 11:
2840 divided by 638 is 4 with a remainder of 288.
The number 4 becomes the next digit in our result. 
Result so far: 42406.324
Subtracting 2552 from 2840 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 12:
When dividing 2880 by 638, we get 4 with a remainder of 328.
Put 4 as the next digit of the answer. 
Result so far: 42406.3244
Subtract 2552 from 2880 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final outcome is 42406.3244, with a leftover of 0.00328.
