154443 divided by 31 
The aim is to understand the frequency of 31 in 154443.

Going ahead to step 1:
31 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 31

Step 2:
15 divided by 31 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 31

Going ahead to step 3:
The number 31 fits into 154 4 times, leaving a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 124 from 154, we get 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 31

Let's proceed to step 4:
The number 31 fits into 304 9 times, leaving a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Deduct 279 from 304 and we're left with 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 31

On to step 5:
The number 31 fits into 254 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 498.0
Deduct 248 from 254 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 31

Going ahead to step 6:
31 goes into 63 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 4982.0
If we take 62 away from 63, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 31, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 4982.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
31 goes into 100 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 4982.03
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 4982.032
Deduct 62 from 70 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
If we divide 80 by 31, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 4982.0322
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 4982.0322, with a leftover of 0.00018.
