We're dividing 30394192 by 451 
Our goal is to divide 30394192 by 451.

Advancing to step 1:
If we divide 3 by 451, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 451

Moving on to step 2:
451 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 451

Going ahead to step 3:
The number 451 fits into 303 0 times, leaving a remainder of 303.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 303 leaves us with 303.
Bring next digit (9) of the dividend behind the 303 and repeat the process: 3039 / 451

Moving on to step 4:
When dividing 3039 by 451, we get 6 with a remainder of 333.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 2706 from 3039 leaves us with 333.
Fetch the next digit (4) from the dividend, attach it to 333 and continue: 3334 / 451

Step 5:
451 goes into 3334 7 times with a remainder of 177.
Write down 7 as next digit of the result. 
Result so far: 67.0
The remainder is 177 after subtracting 3157 from 3334.
Bring next digit (1) of the dividend behind the 177 and repeat the process: 1771 / 451

Step 6:
1771 divided by 451 is 3 with a remainder of 418.
The next digit of our result is 3. 
Result so far: 673.0
If we take 1353 away from 1771, we end up with 418.
Grab the next digit (9) from the dividend, add it to 418, then carry on: 4189 / 451

Advancing to step 7:
The number 451 fits into 4189 9 times, leaving a remainder of 130.
The number 9 becomes the next digit in our result. 
Result so far: 6739.0
Subtracting 4059 from 4189 leaves us with 130.
Bring next digit (2) of the dividend behind the 130 and repeat the process: 1302 / 451

Moving on to step 8:
451 goes into 1302 2 times with a remainder of 400.
The number 2 becomes the next digit in our result. 
Result so far: 67392.0
If we subtract 902 from 1302, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 9:
When dividing 4000 by 451, we get 8 with a remainder of 392.
Record the quotient 8 as the next digit in the result. 
Result so far: 67392.8
Subtracting 3608 from 4000 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 10:
If we divide 3920 by 451, we get 8 and a remainder of 312.
Record the quotient 8 as the next digit in the result. 
Result so far: 67392.88
If we take 3608 away from 3920, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The quotient of the division is 67392.88, and the remainder is 0.312.
