We're dividing 18150812 by 789 
Let's see how many times 789 fits into 18150812.

Advancing to step 1:
The number 789 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 789

On to step 2:
18 divided by 789 is 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 789

On to step 3:
789 can be fit into 181 0 times, resulting in a remainder of 181.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 181, we get 181.
Bring next digit (5) of the dividend behind the 181 and repeat the process: 1815 / 789

Going ahead to step 4:
1815 divided by 789 is 2 with a remainder of 237.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1578 from 1815 to get 237.
Include the next digit (0) from the dividend after 237, then repeat: 2370 / 789

Step 5:
789 can be fit into 2370 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
The remainder is 3 after subtracting 2367 from 2370.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 789

Advancing to step 6:
38 divided by 789 is 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 230.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 789

Let's proceed to step 7:
When dividing 381 by 789, we get 0 with a remainder of 381.
Record the quotient 0 as the next digit in the result. 
Result so far: 2300.0
The remainder is 381 after subtracting 0 from 381.
Include the next digit (2) from the dividend after 381, then repeat: 3812 / 789

On to step 8:
If we divide 3812 by 789, we get 4 and a remainder of 656.
Write down 4 as next digit of the result. 
Result so far: 23004.0
The remainder is 656 after subtracting 3156 from 3812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 9:
When dividing 6560 by 789, we get 8 with a remainder of 248.
Put 8 as the next digit of the answer. 
Result so far: 23004.8
If we take 6312 away from 6560, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 10:
If we divide 2480 by 789, we get 3 and a remainder of 113.
Record the quotient 3 as the next digit in the result. 
Result so far: 23004.83
If we subtract 2367 from 2480, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 11:
If we divide 1130 by 789, we get 1 and a remainder of 341.
Record the quotient 1 as the next digit in the result. 
Result so far: 23004.831
If we take 789 away from 1130, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 12:
The number 789 fits into 3410 4 times, leaving a remainder of 254.
Put 4 as the next digit of the answer. 
Result so far: 23004.8314
If we subtract 3156 from 3410, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 13:
789 can be fit into 2540 3 times, resulting in a remainder of 173.
The number 3 becomes the next digit in our result. 
Result so far: 23004.83143
If we take 2367 away from 2540, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 14:
1730 divided by 789 is 2 with a remainder of 152.
Write down 2 as next digit of the result. 
Result so far: 23004.831432
Subtract 1578 from 1730 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 15:
If we divide 1520 by 789, we get 1 and a remainder of 731.
Write down 1 as next digit of the result. 
Result so far: 23004.8314321
Subtract 789 from 1520 to get 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Going ahead to step 16:
If we divide 7310 by 789, we get 9 and a remainder of 209.
The number 9 becomes the next digit in our result. 
Result so far: 23004.83143219
If we take 7101 away from 7310, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

After the division, we end up with 23004.83143219 and a remainder of 2.09e-07.
