We look at the division of 30270751 by 398 
We want to figure out the number of times 30270751 can be divided by 398.

Let's proceed to step 1:
The number 398 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
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 / 398

Going ahead to step 2:
When dividing 30 by 398, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 398

Let's proceed to step 3:
398 can be fit into 302 0 times, resulting in a remainder of 302.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 302 and we're left with 302.
Fetch the next digit (7) from the dividend, attach it to 302 and continue: 3027 / 398

Moving on to step 4:
3027 divided by 398 is 7 with a remainder of 241.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 2786 from 3027 to get 241.
Bring next digit (0) of the dividend behind the 241 and repeat the process: 2410 / 398

Step 5:
2410 divided by 398 is 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
If we subtract 2388 from 2410, we get 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 398

Step 6:
When dividing 227 by 398, we get 0 with a remainder of 227.
The number 0 becomes the next digit in our result. 
Result so far: 760.0
Deduct 0 from 227 and we're left with 227.
Take the next digit (5) from the dividend and append it to 227, then repeat: 2275 / 398

Let's proceed to step 7:
The number 398 fits into 2275 5 times, leaving a remainder of 285.
The next digit of our result is 5. 
Result so far: 7605.0
Subtracting 1990 from 2275 leaves us with 285.
Bring next digit (1) of the dividend behind the 285 and repeat the process: 2851 / 398

Moving on to step 8:
If we divide 2851 by 398, we get 7 and a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 76057.0
Subtract 2786 from 2851 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
398 can be fit into 650 1 times, resulting in a remainder of 252.
Write down 1 as next digit of the result. 
Result so far: 76057.1
Subtracting 398 from 650 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 10:
When dividing 2520 by 398, we get 6 with a remainder of 132.
The next digit of our result is 6. 
Result so far: 76057.16
Subtracting 2388 from 2520 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 11:
If we divide 1320 by 398, we get 3 and a remainder of 126.
The number 3 becomes the next digit in our result. 
Result so far: 76057.163
The remainder is 126 after subtracting 1194 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 12:
When dividing 1260 by 398, we get 3 with a remainder of 66.
The next digit of our result is 3. 
Result so far: 76057.1633
If we take 1194 away from 1260, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 76057.1633 with a remaining 0.00066.
