We're dividing 754529 by 31 
The aim is to understand the frequency of 31 in 754529.

Step 1:
If we divide 7 by 31, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 31

Step 2:
The number 31 fits into 75 2 times, leaving a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 62 from 75 to get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 31

Let's proceed to step 3:
31 can be fit into 134 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 124 from 134, we get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 31

Advancing to step 4:
If we divide 105 by 31, we get 3 and a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 243.0
The remainder is 12 after subtracting 93 from 105.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 31

Step 5:
If we divide 122 by 31, we get 3 and a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 2433.0
If we take 93 away from 122, we end up with 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 31

On to step 6:
31 goes into 299 9 times with a remainder of 20.
The next digit of our result is 9. 
Result so far: 24339.0
Deduct 279 from 299 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
200 divided by 31 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 24339.6
The remainder is 14 after subtracting 186 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
140 divided by 31 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 24339.64
If we take 124 away from 140, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
The number 31 fits into 160 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 24339.645
If we take 155 away from 160, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
When dividing 50 by 31, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 24339.6451
Deduct 31 from 50 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
The number 31 fits into 190 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 24339.64516
If we take 186 away from 190, we end up 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.

Step 12:
When dividing 40 by 31, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 24339.645161
Subtract 31 from 40 to 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.

Step 13:
31 goes into 90 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 24339.6451612
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.

Step 14:
When dividing 280 by 31, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 24339.64516129
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.

Our division results in 24339.64516129 with a remaining 1e-09.
