Let's divide 66364004 by 638
We're looking to find how many times 638 goes into 66364004.

Step 1:
The number 638 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 638

Moving on to step 2:
66 divided by 638 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 638

Step 3:
If we divide 663 by 638, we get 1 and a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 638 from 663 leaves us with 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 638

Step 4:
When dividing 256 by 638, we get 0 with a remainder of 256.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 256 after subtracting 0 from 256.
Fetch the next digit (4) from the dividend, attach it to 256 and continue: 2564 / 638

Advancing to step 5:
2564 divided by 638 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Deduct 2552 from 2564 and we're left with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 638

On to step 6:
The number 638 fits into 120 0 times, leaving a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 1040.0
If we subtract 0 from 120, we get 120.
Append the next digit (0) from the dividend to 120 and continue with: 1200 / 638

Moving on to step 7:
1200 divided by 638 is 1 with a remainder of 562.
Write down 1 as next digit of the result. 
Result so far: 10401.0
If we subtract 638 from 1200, we get 562.
Fetch the next digit (4) from the dividend, attach it to 562 and continue: 5624 / 638

Step 8:
5624 divided by 638 is 8 with a remainder of 520.
The number 8 becomes the next digit in our result. 
Result so far: 104018.0
If we take 5104 away from 5624, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 9:
5200 divided by 638 is 8 with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 104018.8
The remainder is 96 after subtracting 5104 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 10:
638 can be fit into 960 1 times, resulting in a remainder of 322.
The number 1 becomes the next digit in our result. 
Result so far: 104018.81
Deduct 638 from 960 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 11:
The number 638 fits into 3220 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 104018.815
The remainder is 30 after subtracting 3190 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
When dividing 300 by 638, we get 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 104018.815
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 13:
3000 divided by 638 is 4 with a remainder of 448.
Write down 4 as next digit of the result. 
Result so far: 104018.81504
Subtracting 2552 from 3000 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 14:
4480 divided by 638 is 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 104018.815047
Subtract 4466 from 4480 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 15:
638 can be fit into 140 0 times, resulting in a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 104018.815047
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
If we divide 1400 by 638, we get 2 and a remainder of 124.
The next digit of our result is 2. 
Result so far: 104018.81504702
Deduct 1276 from 1400 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 104018.81504702 with a remainder of 1.24e-07.
