18049752 ÷ 678 
We want to figure out the number of times 18049752 can be divided by 678.

Step 1:
1 divided by 678 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 678

Step 2:
If we divide 18 by 678, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 678

Advancing to step 3:
The number 678 fits into 180 0 times, leaving a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 180, we get 180.
Fetch the next digit (4) from the dividend, attach it to 180 and continue: 1804 / 678

On to step 4:
1804 divided by 678 is 2 with a remainder of 448.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1356 from 1804, we get 448.
Append the next digit (9) from the dividend to 448 and continue with: 4489 / 678

Step 5:
678 can be fit into 4489 6 times, resulting in a remainder of 421.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we subtract 4068 from 4489, we get 421.
Fetch the next digit (7) from the dividend, attach it to 421 and continue: 4217 / 678

Moving on to step 6:
4217 divided by 678 is 6 with a remainder of 149.
Put 6 as the next digit of the answer. 
Result so far: 266.0
Subtract 4068 from 4217 to get 149.
Fetch the next digit (5) from the dividend, attach it to 149 and continue: 1495 / 678

Step 7:
678 can be fit into 1495 2 times, resulting in a remainder of 139.
Put 2 as the next digit of the answer. 
Result so far: 2662.0
If we subtract 1356 from 1495, we get 139.
Include the next digit (2) from the dividend after 139, then repeat: 1392 / 678

Step 8:
678 can be fit into 1392 2 times, resulting in a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 26622.0
If we take 1356 away from 1392, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
The number 678 fits into 360 0 times, leaving a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 26622.0
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
678 goes into 3600 5 times with a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 26622.05
If we subtract 3390 from 3600, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 11:
678 goes into 2100 3 times with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 26622.053
If we subtract 2034 from 2100, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 12:
660 divided by 678 is 0 with a remainder of 660.
Use 0 as the next digit of our solution. 
Result so far: 26622.053
The remainder is 660 after subtracting 0 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 13:
If we divide 6600 by 678, we get 9 and a remainder of 498.
Use 9 as the next digit of our solution. 
Result so far: 26622.05309
If we subtract 6102 from 6600, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Step 14:
4980 divided by 678 is 7 with a remainder of 234.
Record the quotient 7 as the next digit in the result. 
Result so far: 26622.053097
If we subtract 4746 from 4980, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 15:
2340 divided by 678 is 3 with a remainder of 306.
Put 3 as the next digit of the answer. 
Result so far: 26622.0530973
Deduct 2034 from 2340 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 16:
678 can be fit into 3060 4 times, resulting in a remainder of 348.
Record the quotient 4 as the next digit in the result. 
Result so far: 26622.05309734
If we take 2712 away from 3060, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

After the division, we end up with 26622.05309734 and a remainder of 3.48e-07.
