We're dividing 27189031 by 398 
The aim is to understand the frequency of 398 in 27189031.

Let's proceed to step 1:
398 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 398

On to step 2:
27 divided by 398 is 0 with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 398

Moving on to step 3:
398 goes into 271 0 times with a remainder of 271.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 271 after subtracting 0 from 271.
Append the next digit (8) from the dividend to 271 and continue with: 2718 / 398

Step 4:
398 goes into 2718 6 times with a remainder of 330.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 330 after subtracting 2388 from 2718.
Append the next digit (9) from the dividend to 330 and continue with: 3309 / 398

Let's proceed to step 5:
If we divide 3309 by 398, we get 8 and a remainder of 125.
Write down 8 as next digit of the result. 
Result so far: 68.0
If we take 3184 away from 3309, we end up with 125.
Include the next digit (0) from the dividend after 125, then repeat: 1250 / 398

On to step 6:
If we divide 1250 by 398, we get 3 and a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 683.0
Subtract 1194 from 1250 to get 56.
Take the next digit (3) from the dividend and append it to 56, then repeat: 563 / 398

Advancing to step 7:
The number 398 fits into 563 1 times, leaving a remainder of 165.
Record the quotient 1 as the next digit in the result. 
Result so far: 6831.0
If we take 398 away from 563, we end up with 165.
Take the next digit (1) from the dividend and append it to 165, then repeat: 1651 / 398

Going ahead to step 8:
If we divide 1651 by 398, we get 4 and a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 68314.0
If we take 1592 away from 1651, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 9:
If we divide 590 by 398, we get 1 and a remainder of 192.
Write down 1 as next digit of the result. 
Result so far: 68314.1
If we take 398 away from 590, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 10:
The number 398 fits into 1920 4 times, leaving a remainder of 328.
Write down 4 as next digit of the result. 
Result so far: 68314.14
Subtracting 1592 from 1920 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 11:
398 goes into 3280 8 times with a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 68314.148
Subtract 3184 from 3280 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 12:
If we divide 960 by 398, we get 2 and a remainder of 164.
Use 2 as the next digit of our solution. 
Result so far: 68314.1482
If we take 796 away from 960, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 13:
The number 398 fits into 1640 4 times, leaving a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 68314.14824
Deduct 1592 from 1640 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
When dividing 480 by 398, we get 1 with a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 68314.148241
Deduct 398 from 480 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 15:
398 can be fit into 820 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 68314.1482412
If we take 796 away from 820, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 16:
240 divided by 398 is 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 68314.1482412
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

In conclusion, the division gives 68314.1482412 with a balance of 2.4e-07.
