We're dividing 76104007 by 398 
Let's see how many times 398 fits into 76104007.

Step 1:
398 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 398

Moving on to step 2:
76 divided by 398 is 0 with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Fetch the next digit (1) from the dividend, attach it to 76 and continue: 761 / 398

Moving on to step 3:
398 goes into 761 1 times with a remainder of 363.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 398 from 761 to get 363.
Include the next digit (0) from the dividend after 363, then repeat: 3630 / 398

Moving on to step 4:
The number 398 fits into 3630 9 times, leaving a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 48 after subtracting 3582 from 3630.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 398

On to step 5:
484 divided by 398 is 1 with a remainder of 86.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
The remainder is 86 after subtracting 398 from 484.
Append the next digit (0) from the dividend to 86 and continue with: 860 / 398

Going ahead to step 6:
860 divided by 398 is 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 1912.0
Subtracting 796 from 860 leaves us with 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 398

Let's proceed to step 7:
The number 398 fits into 640 1 times, leaving a remainder of 242.
Put 1 as the next digit of the answer. 
Result so far: 19121.0
If we take 398 away from 640, we end up with 242.
Include the next digit (7) from the dividend after 242, then repeat: 2427 / 398

Step 8:
398 can be fit into 2427 6 times, resulting in a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 191216.0
Subtract 2388 from 2427 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
390 divided by 398 is 0 with a remainder of 390.
The next digit of our result is 0. 
Result so far: 191216.0
If we take 0 away from 390, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
The number 398 fits into 3900 9 times, leaving a remainder of 318.
The number 9 becomes the next digit in our result. 
Result so far: 191216.09
Subtract 3582 from 3900 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 11:
If we divide 3180 by 398, we get 7 and a remainder of 394.
The number 7 becomes the next digit in our result. 
Result so far: 191216.097
If we subtract 2786 from 3180, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 12:
If we divide 3940 by 398, we get 9 and a remainder of 358.
The number 9 becomes the next digit in our result. 
Result so far: 191216.0979
Subtract 3582 from 3940 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 13:
The number 398 fits into 3580 8 times, leaving a remainder of 396.
Write down 8 as next digit of the result. 
Result so far: 191216.09798
If we take 3184 away from 3580, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 14:
3960 divided by 398 is 9 with a remainder of 378.
Record the quotient 9 as the next digit in the result. 
Result so far: 191216.097989
Subtracting 3582 from 3960 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 15:
The number 398 fits into 3780 9 times, leaving a remainder of 198.
Record the quotient 9 as the next digit in the result. 
Result so far: 191216.0979899
Subtracting 3582 from 3780 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

The final outcome is 191216.0979899, with a leftover of 1.98e-06.
