We're dividing 64302678 by 638 
We want to figure out the number of times 64302678 can be divided by 638.

Moving on to step 1:
6 divided by 638 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 638

Step 2:
The number 638 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 638

Advancing to step 3:
If we divide 643 by 638, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 638 from 643, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 638

Moving on to step 4:
50 divided by 638 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 50, we end up with 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 638

Moving on to step 5:
If we divide 502 by 638, we get 0 and a remainder of 502.
The next digit of our result is 0. 
Result so far: 100.0
If we take 0 away from 502, we end up with 502.
Grab the next digit (6) from the dividend, add it to 502, then carry on: 5026 / 638

Let's proceed to step 6:
638 can be fit into 5026 7 times, resulting in a remainder of 560.
Record the quotient 7 as the next digit in the result. 
Result so far: 1007.0
Subtracting 4466 from 5026 leaves us with 560.
Take the next digit (7) from the dividend and append it to 560, then repeat: 5607 / 638

Moving on to step 7:
5607 divided by 638 is 8 with a remainder of 503.
Write down 8 as next digit of the result. 
Result so far: 10078.0
Deduct 5104 from 5607 and we're left with 503.
Bring next digit (8) of the dividend behind the 503 and repeat the process: 5038 / 638

On to step 8:
When dividing 5038 by 638, we get 7 with a remainder of 572.
Use 7 as the next digit of our solution. 
Result so far: 100787.0
Subtracting 4466 from 5038 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Moving on to step 9:
638 goes into 5720 8 times with a remainder of 616.
Record the quotient 8 as the next digit in the result. 
Result so far: 100787.8
The remainder is 616 after subtracting 5104 from 5720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 10:
638 can be fit into 6160 9 times, resulting in a remainder of 418.
Write down 9 as next digit of the result. 
Result so far: 100787.89
Subtract 5742 from 6160 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 11:
638 can be fit into 4180 6 times, resulting in a remainder of 352.
Put 6 as the next digit of the answer. 
Result so far: 100787.896
If we subtract 3828 from 4180, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 12:
638 can be fit into 3520 5 times, resulting in a remainder of 330.
Use 5 as the next digit of our solution. 
Result so far: 100787.8965
If we take 3190 away from 3520, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 13:
638 can be fit into 3300 5 times, resulting in a remainder of 110.
The next digit of our result is 5. 
Result so far: 100787.89655
If we take 3190 away from 3300, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 100787.89655 and a remainder of 0.00011.
