Let's divide 30010431 by 769
Our goal is to divide 30010431 by 769.

Going ahead to step 1:
If we divide 3 by 769, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 769

On to step 2:
If we divide 30 by 769, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 769

Step 3:
The number 769 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 300 to get 300.
Take the next digit (1) from the dividend and append it to 300, then repeat: 3001 / 769

Advancing to step 4:
3001 divided by 769 is 3 with a remainder of 694.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 2307 from 3001 to get 694.
Append the next digit (0) from the dividend to 694 and continue with: 6940 / 769

Let's proceed to step 5:
769 goes into 6940 9 times with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 19 after subtracting 6921 from 6940.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 769

On to step 6:
194 divided by 769 is 0 with a remainder of 194.
Write down 0 as next digit of the result. 
Result so far: 390.0
If we subtract 0 from 194, we get 194.
Fetch the next digit (3) from the dividend, attach it to 194 and continue: 1943 / 769

On to step 7:
1943 divided by 769 is 2 with a remainder of 405.
Put 2 as the next digit of the answer. 
Result so far: 3902.0
If we take 1538 away from 1943, we end up with 405.
Append the next digit (1) from the dividend to 405 and continue with: 4051 / 769

Let's proceed to step 8:
769 can be fit into 4051 5 times, resulting in a remainder of 206.
Write down 5 as next digit of the result. 
Result so far: 39025.0
If we take 3845 away from 4051, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 9:
769 can be fit into 2060 2 times, resulting in a remainder of 522.
Use 2 as the next digit of our solution. 
Result so far: 39025.2
Subtract 1538 from 2060 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

On to step 10:
If we divide 5220 by 769, we get 6 and a remainder of 606.
Use 6 as the next digit of our solution. 
Result so far: 39025.26
Subtract 4614 from 5220 to get 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Advancing to step 11:
If we divide 6060 by 769, we get 7 and a remainder of 677.
Put 7 as the next digit of the answer. 
Result so far: 39025.267
The remainder is 677 after subtracting 5383 from 6060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Going ahead to step 12:
769 goes into 6770 8 times with a remainder of 618.
Put 8 as the next digit of the answer. 
Result so far: 39025.2678
Subtract 6152 from 6770 to get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Going ahead to step 13:
The number 769 fits into 6180 8 times, leaving a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 39025.26788
Subtracting 6152 from 6180 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.

The quotient of the division is 39025.26788, and the remainder is 2.8e-05.
