657766 ÷ 31 
The aim is to understand the frequency of 31 in 657766.

Let's proceed to step 1:
31 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 31

Let's proceed to step 2:
65 divided by 31 is 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
If we take 62 away from 65, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 31

Step 3:
31 goes into 37 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 31 from 37 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 31

Advancing to step 4:
The number 31 fits into 67 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 212.0
Deduct 62 from 67 and we're left with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 31

On to step 5:
The number 31 fits into 56 1 times, leaving a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 2121.0
Subtract 31 from 56 to get 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 31

Moving on to step 6:
When dividing 256 by 31, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 21218.0
Subtracting 248 from 256 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.

Going ahead to step 7:
When dividing 80 by 31, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 21218.2
Deduct 62 from 80 and we're left 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.

Going ahead to step 8:
If we divide 180 by 31, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 21218.25
The remainder is 25 after subtracting 155 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
31 can be fit into 250 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 21218.258
Subtracting 248 from 250 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
31 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 21218.258
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
When dividing 200 by 31, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 21218.25806
If we take 186 away from 200, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
31 can be fit into 140 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 21218.258064
Subtracting 124 from 140 leaves us 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.

Moving on to step 13:
160 divided by 31 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 21218.2580645
Deduct 155 from 160 and we're left 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.

Going ahead to step 14:
When dividing 50 by 31, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 21218.25806451
If we subtract 31 from 50, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 21218.25806451 and a remainder of 1.9e-08.
