Let's divide 136411 by 31
The aim is to understand the frequency of 31 in 136411.

On to step 1:
When dividing 1 by 31, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 31

Moving on to step 2:
31 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 31

Moving on to step 3:
31 can be fit into 136 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 12 after subtracting 124 from 136.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 31

On to step 4:
The number 31 fits into 124 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 44.0
If we take 124 away from 124, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 31

Going ahead to step 5:
1 divided by 31 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 440.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 31

On to step 6:
31 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 4400.0
The remainder is 11 after subtracting 0 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
110 divided by 31 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 4400.3
Deduct 93 from 110 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 8:
31 goes into 170 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 4400.35
Subtract 155 from 170 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
The number 31 fits into 150 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 4400.354
Deduct 124 from 150 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
31 goes into 260 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 4400.3548
Deduct 248 from 260 and we're left 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 11:
If we divide 120 by 31, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 4400.35483
If we take 93 away from 120, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
If we divide 270 by 31, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 4400.354838
Deduct 248 from 270 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
When dividing 220 by 31, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 4400.3548387
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.

On to step 14:
31 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 4400.3548387
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 4400.3548387 and a remainder of 3e-08.
