We divide 909232 by 31
The aim is to understand the frequency of 31 in 909232.

Advancing to step 1:
9 divided by 31 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 31

Going ahead to step 2:
When dividing 90 by 31, we get 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 2.0
If we take 62 away from 90, we end up with 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 31

Going ahead to step 3:
When dividing 289 by 31, we get 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 279 from 289 to get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 31

Step 4:
31 goes into 102 3 times with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 293.0
The remainder is 9 after subtracting 93 from 102.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 31

Moving on to step 5:
If we divide 93 by 31, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 2933.0
If we take 93 away from 93, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 31

Step 6:
The number 31 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 29330.0
If we subtract 0 from 2, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 31 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 29330.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
31 goes into 200 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 29330.06
If we take 186 away from 200, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
31 can be fit into 140 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 29330.064
The remainder is 16 after subtracting 124 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
31 goes into 160 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 29330.0645
Subtract 155 from 160 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
50 divided by 31 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 29330.06451
The remainder is 19 after subtracting 31 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
When dividing 190 by 31, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 29330.064516
Deduct 186 from 190 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
When dividing 40 by 31, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 29330.0645161
If we subtract 31 from 40, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
31 goes into 90 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 29330.06451612
Subtract 62 from 90 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 29330.06451612 with a remaining 2.8e-08.
