We divide 12618748 by 638
We're looking to find how many times 638 goes into 12618748.

Step 1:
The number 638 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 638

Let's proceed to step 2:
12 divided by 638 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 638

On to step 3:
If we divide 126 by 638, we get 0 and a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 126 and we're left with 126.
Take the next digit (1) from the dividend and append it to 126, then repeat: 1261 / 638

Moving on to step 4:
The number 638 fits into 1261 1 times, leaving a remainder of 623.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 638 from 1261 leaves us with 623.
Append the next digit (8) from the dividend to 623 and continue with: 6238 / 638

Moving on to step 5:
6238 divided by 638 is 9 with a remainder of 496.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 5742 from 6238 leaves us with 496.
Fetch the next digit (7) from the dividend, attach it to 496 and continue: 4967 / 638

Moving on to step 6:
When dividing 4967 by 638, we get 7 with a remainder of 501.
Put 7 as the next digit of the answer. 
Result so far: 197.0
If we subtract 4466 from 4967, we get 501.
Include the next digit (4) from the dividend after 501, then repeat: 5014 / 638

Step 7:
When dividing 5014 by 638, we get 7 with a remainder of 548.
The next digit of our result is 7. 
Result so far: 1977.0
Subtracting 4466 from 5014 leaves us with 548.
Bring next digit (8) of the dividend behind the 548 and repeat the process: 5488 / 638

Moving on to step 8:
When dividing 5488 by 638, we get 8 with a remainder of 384.
Put 8 as the next digit of the answer. 
Result so far: 19778.0
If we take 5104 away from 5488, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 9:
The number 638 fits into 3840 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 19778.6
Subtract 3828 from 3840 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.

Moving on to step 10:
If we divide 120 by 638, we get 0 and a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 19778.6
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
638 can be fit into 1200 1 times, resulting in a remainder of 562.
Use 1 as the next digit of our solution. 
Result so far: 19778.601
If we subtract 638 from 1200, we get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 12:
If we divide 5620 by 638, we get 8 and a remainder of 516.
Put 8 as the next digit of the answer. 
Result so far: 19778.6018
If we subtract 5104 from 5620, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 13:
638 can be fit into 5160 8 times, resulting in a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 19778.60188
Subtract 5104 from 5160 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 19778.60188 with a remainder of 5.6e-05.
