Let's divide 57247714 by 398
The aim is to understand the frequency of 398 in 57247714.

On to step 1:
If we divide 5 by 398, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 398

Going ahead to step 2:
398 goes into 57 0 times with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 398

Going ahead to step 3:
398 can be fit into 572 1 times, resulting in a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 398 from 572 leaves us with 174.
Append the next digit (4) from the dividend to 174 and continue with: 1744 / 398

Step 4:
398 goes into 1744 4 times with a remainder of 152.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 152 after subtracting 1592 from 1744.
Include the next digit (7) from the dividend after 152, then repeat: 1527 / 398

Moving on to step 5:
398 goes into 1527 3 times with a remainder of 333.
Use 3 as the next digit of our solution. 
Result so far: 143.0
The remainder is 333 after subtracting 1194 from 1527.
Append the next digit (7) from the dividend to 333 and continue with: 3337 / 398

Step 6:
The number 398 fits into 3337 8 times, leaving a remainder of 153.
The number 8 becomes the next digit in our result. 
Result so far: 1438.0
The remainder is 153 after subtracting 3184 from 3337.
Append the next digit (1) from the dividend to 153 and continue with: 1531 / 398

Step 7:
When dividing 1531 by 398, we get 3 with a remainder of 337.
Use 3 as the next digit of our solution. 
Result so far: 14383.0
Subtract 1194 from 1531 to get 337.
Include the next digit (4) from the dividend after 337, then repeat: 3374 / 398

Let's proceed to step 8:
398 can be fit into 3374 8 times, resulting in a remainder of 190.
The next digit of our result is 8. 
Result so far: 143838.0
The remainder is 190 after subtracting 3184 from 3374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 9:
When dividing 1900 by 398, we get 4 with a remainder of 308.
The number 4 becomes the next digit in our result. 
Result so far: 143838.4
The remainder is 308 after subtracting 1592 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 10:
When dividing 3080 by 398, we get 7 with a remainder of 294.
Record the quotient 7 as the next digit in the result. 
Result so far: 143838.47
The remainder is 294 after subtracting 2786 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 11:
398 goes into 2940 7 times with a remainder of 154.
Write down 7 as next digit of the result. 
Result so far: 143838.477
Deduct 2786 from 2940 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

In conclusion, the division gives 143838.477 with a balance of 0.0154.
