33617 divided by 31 
The aim is to understand the frequency of 31 in 33617.

Advancing to step 1:
The number 31 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 31

Step 2:
If we divide 33 by 31, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 31 away from 33, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 31

Step 3:
26 divided by 31 is 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 26 after subtracting 0 from 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 31

On to step 4:
261 divided by 31 is 8 with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtract 248 from 261 to get 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 31

Advancing to step 5:
31 goes into 137 4 times with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 1084.0
If we take 124 away from 137, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 6:
31 can be fit into 130 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1084.4
Subtracting 124 from 130 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
When dividing 60 by 31, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1084.41
The remainder is 29 after subtracting 31 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
The number 31 fits into 290 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1084.419
Subtract 279 from 290 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
110 divided by 31 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 1084.4193
Subtracting 93 from 110 leaves us 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.

Step 10:
31 goes into 170 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 1084.41935
If we take 155 away from 170, we end up with 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 11:
31 can be fit into 150 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 1084.419354
If we subtract 124 from 150, we 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 12:
260 divided by 31 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1084.4193548
Subtract 248 from 260 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
If we divide 120 by 31, we get 3 and a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 1084.41935483
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.

After the division, we end up with 1084.41935483 and a remainder of 2.7e-08.
