747882 divided by 31 
The aim is to understand the frequency of 31 in 747882.

Going ahead to step 1:
31 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 31

Advancing to step 2:
When dividing 74 by 31, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 62 from 74, we get 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 31

Going ahead to step 3:
127 divided by 31 is 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 124 from 127 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 31

Let's proceed to step 4:
31 goes into 38 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 241.0
If we take 31 away from 38, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 31

Going ahead to step 5:
When dividing 78 by 31, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2412.0
If we take 62 away from 78, we end up with 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 31

Let's proceed to step 6:
When dividing 162 by 31, we get 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 24125.0
Subtract 155 from 162 to 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.

Advancing to step 7:
31 goes into 70 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 24125.2
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.

Step 8:
80 divided by 31 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 24125.22
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 24125.22 and a remainder of 0.018.
