912060 divided by 31 
The aim is to understand the frequency of 31 in 912060.

Step 1:
9 divided by 31 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 31

Moving on to step 2:
If we divide 91 by 31, we get 2 and a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 62 from 91 to get 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 31

Let's proceed to step 3:
When dividing 292 by 31, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtract 279 from 292 to get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 31

On to step 4:
When dividing 130 by 31, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 294.0
If we subtract 124 from 130, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 31

Let's proceed to step 5:
31 can be fit into 66 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2942.0
Deduct 62 from 66 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 31

On to step 6:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 29421.0
If we take 31 away from 40, we end up with 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 7:
The number 31 fits into 90 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 29421.2
Subtracting 62 from 90 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
If we divide 280 by 31, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 29421.29
Deduct 279 from 280 and we're left 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.

Let's proceed to step 9:
10 divided by 31 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 29421.29
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
When dividing 100 by 31, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 29421.2903
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.

Step 11:
The number 31 fits into 70 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 29421.29032
If we subtract 62 from 70, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
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: 29421.290322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 29421.290322 with a remaining 1.8e-06.
