Let's divide 889881 by 31
The aim is to understand the frequency of 31 in 889881.

Step 1:
31 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 31

Advancing to step 2:
If we divide 88 by 31, we get 2 and a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 26 after subtracting 62 from 88.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 31

Step 3:
The number 31 fits into 269 8 times, leaving a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 248 from 269 and we're left with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 31

Moving on to step 4:
31 goes into 218 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 287.0
If we subtract 217 from 218, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 31

Advancing to step 5:
If we divide 18 by 31, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 2870.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 31

Let's proceed to step 6:
181 divided by 31 is 5 with a remainder of 26.
The next digit of our result is 5. 
Result so far: 28705.0
Subtract 155 from 181 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
If we divide 260 by 31, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 28705.8
Subtracting 248 from 260 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
When dividing 120 by 31, we get 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 28705.83
Subtract 93 from 120 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
270 divided by 31 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 28705.838
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
31 can be fit into 220 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 28705.8387
If we take 217 away from 220, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
30 divided by 31 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 28705.8387
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
300 divided by 31 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 28705.838709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
The number 31 fits into 210 6 times, leaving a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 28705.8387096
If we subtract 186 from 210, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
When dividing 240 by 31, we get 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 28705.83870967
Subtracting 217 from 240 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

In conclusion, the division gives 28705.83870967 with a balance of 2.3e-08.
