18788640 ÷ 786 
We're looking to find how many times 786 goes into 18788640.

Let's proceed to step 1:
786 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 786

Step 2:
The number 786 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 786

On to step 3:
The number 786 fits into 187 0 times, leaving a remainder of 187.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 187, we end up with 187.
Fetch the next digit (8) from the dividend, attach it to 187 and continue: 1878 / 786

Advancing to step 4:
The number 786 fits into 1878 2 times, leaving a remainder of 306.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1572 from 1878 to get 306.
Fetch the next digit (8) from the dividend, attach it to 306 and continue: 3068 / 786

On to step 5:
786 can be fit into 3068 3 times, resulting in a remainder of 710.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 710 after subtracting 2358 from 3068.
Append the next digit (6) from the dividend to 710 and continue with: 7106 / 786

Advancing to step 6:
If we divide 7106 by 786, we get 9 and a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 239.0
The remainder is 32 after subtracting 7074 from 7106.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 786

Step 7:
When dividing 324 by 786, we get 0 with a remainder of 324.
Use 0 as the next digit of our solution. 
Result so far: 2390.0
If we subtract 0 from 324, we get 324.
Include the next digit (0) from the dividend after 324, then repeat: 3240 / 786

Let's proceed to step 8:
3240 divided by 786 is 4 with a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 23904.0
If we subtract 3144 from 3240, we get 96.
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 9:
786 goes into 960 1 times with a remainder of 174.
The next digit of our result is 1. 
Result so far: 23904.1
Deduct 786 from 960 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 10:
The number 786 fits into 1740 2 times, leaving a remainder of 168.
The next digit of our result is 2. 
Result so far: 23904.12
Deduct 1572 from 1740 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 11:
When dividing 1680 by 786, we get 2 with a remainder of 108.
Put 2 as the next digit of the answer. 
Result so far: 23904.122
Subtract 1572 from 1680 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 23904.122, with a leftover of 0.0108.
