We look at the division of 754066 by 31 
The aim is to understand the frequency of 31 in 754066.

Let's proceed to step 1:
7 divided by 31 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 31

Advancing to step 2:
When dividing 75 by 31, we get 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 62 from 75 to get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 31

Going ahead to step 3:
The number 31 fits into 134 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 124 from 134 leaves us with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 31

On to step 4:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 243.0
Deduct 93 from 100 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 31

Going ahead to step 5:
76 divided by 31 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2432.0
Subtracting 62 from 76 leaves us with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 31

Let's proceed to step 6:
31 can be fit into 146 4 times, resulting in a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 24324.0
If we take 124 away from 146, we end up 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.

Going ahead to step 7:
If we divide 220 by 31, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 24324.7
Subtracting 217 from 220 leaves us 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 8:
30 divided by 31 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 24324.7
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
31 can be fit into 300 9 times, resulting in a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 24324.709
If we take 279 away from 300, we end up 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.

Let's proceed to step 10:
The number 31 fits into 210 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 24324.7096
Subtracting 186 from 210 leaves us 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.

Step 11:
240 divided by 31 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 24324.70967
Subtracting 217 from 240 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
31 goes into 230 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 24324.709677
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 quotient of the division is 24324.709677, and the remainder is 1.3e-06.
