We look at the division of 46898874 by 398 
The aim is to understand the frequency of 398 in 46898874.

Step 1:
The number 398 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 398

Moving on to step 2:
46 divided by 398 is 0 with a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 46 to get 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 398

Moving on to step 3:
468 divided by 398 is 1 with a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 398 from 468, we get 70.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 398

Going ahead to step 4:
709 divided by 398 is 1 with a remainder of 311.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 398 from 709, we get 311.
Include the next digit (8) from the dividend after 311, then repeat: 3118 / 398

Advancing to step 5:
If we divide 3118 by 398, we get 7 and a remainder of 332.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Deduct 2786 from 3118 and we're left with 332.
Fetch the next digit (8) from the dividend, attach it to 332 and continue: 3328 / 398

Going ahead to step 6:
When dividing 3328 by 398, we get 8 with a remainder of 144.
The number 8 becomes the next digit in our result. 
Result so far: 1178.0
The remainder is 144 after subtracting 3184 from 3328.
Fetch the next digit (7) from the dividend, attach it to 144 and continue: 1447 / 398

Moving on to step 7:
When dividing 1447 by 398, we get 3 with a remainder of 253.
Record the quotient 3 as the next digit in the result. 
Result so far: 11783.0
Subtract 1194 from 1447 to get 253.
Fetch the next digit (4) from the dividend, attach it to 253 and continue: 2534 / 398

Let's proceed to step 8:
If we divide 2534 by 398, we get 6 and a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 117836.0
Subtracting 2388 from 2534 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 9:
398 goes into 1460 3 times with a remainder of 266.
Record the quotient 3 as the next digit in the result. 
Result so far: 117836.3
Subtract 1194 from 1460 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 10:
398 goes into 2660 6 times with a remainder of 272.
The number 6 becomes the next digit in our result. 
Result so far: 117836.36
The remainder is 272 after subtracting 2388 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 11:
The number 398 fits into 2720 6 times, leaving a remainder of 332.
The next digit of our result is 6. 
Result so far: 117836.366
If we take 2388 away from 2720, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The final outcome is 117836.366, with a leftover of 0.0332.
