530153 divided by 31 
The aim is to understand the frequency of 31 in 530153.

On to step 1:
When dividing 5 by 31, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 31

Moving on to step 2:
When dividing 53 by 31, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 22 after subtracting 31 from 53.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 31

Let's proceed to step 3:
31 can be fit into 220 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 217 from 220, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 31

Advancing to step 4:
If we divide 31 by 31, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
Subtracting 31 from 31 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 31

On to step 5:
The number 31 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 1710.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 31

Moving on to step 6:
The number 31 fits into 53 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 17101.0
If we subtract 31 from 53, we get 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 7:
220 divided by 31 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 17101.7
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
When dividing 30 by 31, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 17101.7
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 31, we get 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 17101.709
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
31 can be fit into 210 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 17101.7096
Deduct 186 from 210 and we're left 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.

On to step 11:
The number 31 fits into 240 7 times, leaving a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 17101.70967
The remainder is 23 after subtracting 217 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
If we divide 230 by 31, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 17101.709677
Deduct 217 from 230 and we're left 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.

The final outcome is 17101.709677, with a leftover of 1.3e-06.
