23488262 divided by 398 
The aim is to understand the frequency of 398 in 23488262.

Advancing to step 1:
398 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 398

Moving on to step 2:
When dividing 23 by 398, we get 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 398

Moving on to step 3:
The number 398 fits into 234 0 times, leaving a remainder of 234.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 234 leaves us with 234.
Grab the next digit (8) from the dividend, add it to 234, then carry on: 2348 / 398

Going ahead to step 4:
2348 divided by 398 is 5 with a remainder of 358.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 1990 from 2348 leaves us with 358.
Fetch the next digit (8) from the dividend, attach it to 358 and continue: 3588 / 398

Step 5:
The number 398 fits into 3588 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Deduct 3582 from 3588 and we're left with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 398

Step 6:
398 goes into 62 0 times with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 590.0
If we subtract 0 from 62, we get 62.
Bring next digit (6) of the dividend behind the 62 and repeat the process: 626 / 398

On to step 7:
398 goes into 626 1 times with a remainder of 228.
The number 1 becomes the next digit in our result. 
Result so far: 5901.0
The remainder is 228 after subtracting 398 from 626.
Take the next digit (2) from the dividend and append it to 228, then repeat: 2282 / 398

Going ahead to step 8:
398 goes into 2282 5 times with a remainder of 292.
Use 5 as the next digit of our solution. 
Result so far: 59015.0
Subtracting 1990 from 2282 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 9:
398 can be fit into 2920 7 times, resulting in a remainder of 134.
Use 7 as the next digit of our solution. 
Result so far: 59015.7
Subtracting 2786 from 2920 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 10:
1340 divided by 398 is 3 with a remainder of 146.
The number 3 becomes the next digit in our result. 
Result so far: 59015.73
If we subtract 1194 from 1340, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 11:
1460 divided by 398 is 3 with a remainder of 266.
The next digit of our result is 3. 
Result so far: 59015.733
If we take 1194 away from 1460, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The quotient of the division is 59015.733, and the remainder is 0.0266.
