Let's divide 30213994 by 789
Let's see how many times 789 fits into 30213994.

Step 1:
If we divide 3 by 789, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 789

Step 2:
30 divided by 789 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 789

On to step 3:
If we divide 302 by 789, we get 0 and a remainder of 302.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 302, we end up with 302.
Append the next digit (1) from the dividend to 302 and continue with: 3021 / 789

Let's proceed to step 4:
The number 789 fits into 3021 3 times, leaving a remainder of 654.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 2367 from 3021 leaves us with 654.
Bring next digit (3) of the dividend behind the 654 and repeat the process: 6543 / 789

Let's proceed to step 5:
If we divide 6543 by 789, we get 8 and a remainder of 231.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 6312 from 6543, we get 231.
Include the next digit (9) from the dividend after 231, then repeat: 2319 / 789

Step 6:
When dividing 2319 by 789, we get 2 with a remainder of 741.
Put 2 as the next digit of the answer. 
Result so far: 382.0
Subtract 1578 from 2319 to get 741.
Include the next digit (9) from the dividend after 741, then repeat: 7419 / 789

Moving on to step 7:
7419 divided by 789 is 9 with a remainder of 318.
The number 9 becomes the next digit in our result. 
Result so far: 3829.0
The remainder is 318 after subtracting 7101 from 7419.
Include the next digit (4) from the dividend after 318, then repeat: 3184 / 789

Going ahead to step 8:
3184 divided by 789 is 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 38294.0
Subtracting 3156 from 3184 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
789 goes into 280 0 times with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 38294.0
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 10:
The number 789 fits into 2800 3 times, leaving a remainder of 433.
The number 3 becomes the next digit in our result. 
Result so far: 38294.03
If we take 2367 away from 2800, we end up with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

On to step 11:
When dividing 4330 by 789, we get 5 with a remainder of 385.
Use 5 as the next digit of our solution. 
Result so far: 38294.035
Deduct 3945 from 4330 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 12:
3850 divided by 789 is 4 with a remainder of 694.
The number 4 becomes the next digit in our result. 
Result so far: 38294.0354
If we take 3156 away from 3850, we end up with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Moving on to step 13:
6940 divided by 789 is 8 with a remainder of 628.
Write down 8 as next digit of the result. 
Result so far: 38294.03548
Subtracting 6312 from 6940 leaves us with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Let's proceed to step 14:
When dividing 6280 by 789, we get 7 with a remainder of 757.
The number 7 becomes the next digit in our result. 
Result so far: 38294.035487
Subtracting 5523 from 6280 leaves us with 757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Moving on to step 15:
When dividing 7570 by 789, we get 9 with a remainder of 469.
Write down 9 as next digit of the result. 
Result so far: 38294.0354879
Subtract 7101 from 7570 to get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Going ahead to step 16:
789 can be fit into 4690 5 times, resulting in a remainder of 745.
Use 5 as the next digit of our solution. 
Result so far: 38294.03548795
Deduct 3945 from 4690 and we're left with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Our division results in 38294.03548795 with a remaining 7.45e-07.
