We look at the division of 2952462 by 398 
The aim is to understand the frequency of 398 in 2952462.

Going ahead to step 1:
When dividing 2 by 398, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 398

Step 2:
When dividing 29 by 398, we get 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 398

Moving on to step 3:
398 goes into 295 0 times with a remainder of 295.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 295, we end up with 295.
Fetch the next digit (2) from the dividend, attach it to 295 and continue: 2952 / 398

Let's proceed to step 4:
If we divide 2952 by 398, we get 7 and a remainder of 166.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 2786 away from 2952, we end up with 166.
Bring next digit (4) of the dividend behind the 166 and repeat the process: 1664 / 398

Let's proceed to step 5:
The number 398 fits into 1664 4 times, leaving a remainder of 72.
The next digit of our result is 4. 
Result so far: 74.0
If we take 1592 away from 1664, we end up with 72.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 398

Advancing to step 6:
398 goes into 726 1 times with a remainder of 328.
The next digit of our result is 1. 
Result so far: 741.0
If we subtract 398 from 726, we get 328.
Take the next digit (2) from the dividend and append it to 328, then repeat: 3282 / 398

Let's proceed to step 7:
398 goes into 3282 8 times with a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 7418.0
Deduct 3184 from 3282 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 8:
398 goes into 980 2 times with a remainder of 184.
Write down 2 as next digit of the result. 
Result so far: 7418.2
If we subtract 796 from 980, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 9:
When dividing 1840 by 398, we get 4 with a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 7418.24
If we subtract 1592 from 1840, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 10:
2480 divided by 398 is 6 with a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 7418.246
If we subtract 2388 from 2480, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 11:
The number 398 fits into 920 2 times, leaving a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 7418.2462
Subtract 796 from 920 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 12:
398 goes into 1240 3 times with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 7418.24623
If we subtract 1194 from 1240, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
If we divide 460 by 398, we get 1 and a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 7418.246231
Subtract 398 from 460 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
The number 398 fits into 620 1 times, leaving a remainder of 222.
Use 1 as the next digit of our solution. 
Result so far: 7418.2462311
Subtract 398 from 620 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Our division results in 7418.2462311 with a remaining 2.22e-06.
