We look at the division of 75796895 by 31 
The aim is to understand the frequency of 31 in 75796895.

Step 1:
31 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 31

Step 2:
31 can be fit into 75 2 times, resulting in a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 62 away from 75, we end up with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 31

Going ahead to step 3:
31 can be fit into 137 4 times, resulting in a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 124 away from 137, we end up with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 31

Step 4:
139 divided by 31 is 4 with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 244.0
Subtracting 124 from 139 leaves us with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 31

Going ahead to step 5:
31 goes into 156 5 times with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 2445.0
If we take 155 away from 156, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 31

Advancing to step 6:
18 divided by 31 is 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 24450.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 31

Moving on to step 7:
If we divide 189 by 31, we get 6 and a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 244506.0
Deduct 186 from 189 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 31

Step 8:
35 divided by 31 is 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 2445061.0
Subtracting 31 from 35 leaves us 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 9:
The number 31 fits into 40 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 2445061.1
Deduct 31 from 40 and we're left 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.

Moving on to step 10:
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: 2445061.12
If we take 62 away from 90, we end up 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 11:
If we divide 280 by 31, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 2445061.129
Subtract 279 from 280 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
31 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2445061.129
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.

Step 13:
31 goes into 100 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 2445061.12903
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
If we divide 70 by 31, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 2445061.129032
Subtracting 62 from 70 leaves us with 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 15:
80 divided by 31 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2445061.1290322
Subtracting 62 from 80 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 2445061.1290322 with a remainder of 1.8e-07.
