27209767 divided by 638 
We're looking to find how many times 638 goes into 27209767.

On to step 1:
If we divide 2 by 638, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 638

Advancing to step 2:
The number 638 fits into 27 0 times, leaving a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 638

Moving on to step 3:
If we divide 272 by 638, we get 0 and a remainder of 272.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 272 and we're left with 272.
Append the next digit (0) from the dividend to 272 and continue with: 2720 / 638

On to step 4:
638 can be fit into 2720 4 times, resulting in a remainder of 168.
The next digit of our result is 4. 
Result so far: 4.0
If we take 2552 away from 2720, we end up with 168.
Grab the next digit (9) from the dividend, add it to 168, then carry on: 1689 / 638

Advancing to step 5:
The number 638 fits into 1689 2 times, leaving a remainder of 413.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we take 1276 away from 1689, we end up with 413.
Append the next digit (7) from the dividend to 413 and continue with: 4137 / 638

On to step 6:
638 can be fit into 4137 6 times, resulting in a remainder of 309.
The number 6 becomes the next digit in our result. 
Result so far: 426.0
Subtracting 3828 from 4137 leaves us with 309.
Include the next digit (6) from the dividend after 309, then repeat: 3096 / 638

Advancing to step 7:
638 goes into 3096 4 times with a remainder of 544.
Write down 4 as next digit of the result. 
Result so far: 4264.0
If we subtract 2552 from 3096, we get 544.
Fetch the next digit (7) from the dividend, attach it to 544 and continue: 5447 / 638

Moving on to step 8:
If we divide 5447 by 638, we get 8 and a remainder of 343.
Put 8 as the next digit of the answer. 
Result so far: 42648.0
If we take 5104 away from 5447, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Advancing to step 9:
If we divide 3430 by 638, we get 5 and a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 42648.5
If we subtract 3190 from 3430, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 10:
If we divide 2400 by 638, we get 3 and a remainder of 486.
The number 3 becomes the next digit in our result. 
Result so far: 42648.53
If we subtract 1914 from 2400, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 11:
When dividing 4860 by 638, we get 7 with a remainder of 394.
Write down 7 as next digit of the result. 
Result so far: 42648.537
If we take 4466 away from 4860, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 12:
When dividing 3940 by 638, we get 6 with a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 42648.5376
Subtract 3828 from 3940 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 13:
If we divide 1120 by 638, we get 1 and a remainder of 482.
The number 1 becomes the next digit in our result. 
Result so far: 42648.53761
If we subtract 638 from 1120, we get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 14:
4820 divided by 638 is 7 with a remainder of 354.
Put 7 as the next digit of the answer. 
Result so far: 42648.537617
Subtracting 4466 from 4820 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 15:
The number 638 fits into 3540 5 times, leaving a remainder of 350.
The next digit of our result is 5. 
Result so far: 42648.5376175
Subtract 3190 from 3540 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 16:
638 can be fit into 3500 5 times, resulting in a remainder of 310.
Use 5 as the next digit of our solution. 
Result so far: 42648.53761755
Deduct 3190 from 3500 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final outcome is 42648.53761755, with a leftover of 3.1e-07.
