We're dividing 49628057 by 398 
The aim is to understand the frequency of 398 in 49628057.

Moving on to step 1:
If we divide 4 by 398, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 398

Going ahead to step 2:
398 can be fit into 49 0 times, resulting in a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 398

Going ahead to step 3:
398 can be fit into 496 1 times, resulting in a remainder of 98.
The next digit of our result is 1. 
Result so far: 1.0
If we take 398 away from 496, we end up with 98.
Grab the next digit (2) from the dividend, add it to 98, then carry on: 982 / 398

Step 4:
982 divided by 398 is 2 with a remainder of 186.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 796 from 982 to get 186.
Take the next digit (8) from the dividend and append it to 186, then repeat: 1868 / 398

Advancing to step 5:
1868 divided by 398 is 4 with a remainder of 276.
The next digit of our result is 4. 
Result so far: 124.0
Subtract 1592 from 1868 to get 276.
Grab the next digit (0) from the dividend, add it to 276, then carry on: 2760 / 398

Advancing to step 6:
398 can be fit into 2760 6 times, resulting in a remainder of 372.
The next digit of our result is 6. 
Result so far: 1246.0
If we subtract 2388 from 2760, we get 372.
Fetch the next digit (5) from the dividend, attach it to 372 and continue: 3725 / 398

Moving on to step 7:
The number 398 fits into 3725 9 times, leaving a remainder of 143.
The next digit of our result is 9. 
Result so far: 12469.0
Subtracting 3582 from 3725 leaves us with 143.
Fetch the next digit (7) from the dividend, attach it to 143 and continue: 1437 / 398

Going ahead to step 8:
398 can be fit into 1437 3 times, resulting in a remainder of 243.
Put 3 as the next digit of the answer. 
Result so far: 124693.0
Subtract 1194 from 1437 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 9:
If we divide 2430 by 398, we get 6 and a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 124693.6
Subtract 2388 from 2430 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
When dividing 420 by 398, we get 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 124693.61
The remainder is 22 after subtracting 398 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
If we divide 220 by 398, we get 0 and a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 124693.61
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 12:
398 can be fit into 2200 5 times, resulting in a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 124693.6105
Deduct 1990 from 2200 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 13:
The number 398 fits into 2100 5 times, leaving a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 124693.61055
Subtract 1990 from 2100 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 124693.61055 and a remainder of 0.00011.
