655697 ÷ 31 
The aim is to understand the frequency of 31 in 655697.

Step 1:
31 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 31

Advancing to step 2:
31 goes into 65 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 62 from 65, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 31

Going ahead to step 3:
31 can be fit into 35 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 31 from 35 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 31

Advancing to step 4:
31 can be fit into 46 1 times, resulting in a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 211.0
Subtracting 31 from 46 leaves us with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 31

Going ahead to step 5:
When dividing 159 by 31, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 2115.0
If we subtract 155 from 159, we get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 31

Step 6:
31 goes into 47 1 times with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 21151.0
If we take 31 away from 47, 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.

Moving on to step 7:
If we divide 160 by 31, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 21151.5
If we subtract 155 from 160, we get 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 8:
When dividing 50 by 31, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 21151.51
If we take 31 away from 50, we end up 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.

Advancing to step 9:
The number 31 fits into 190 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 21151.516
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 10:
If we divide 40 by 31, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 21151.5161
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
31 can be fit into 90 2 times, resulting in a remainder of 28.
The next digit of our result is 2. 
Result so far: 21151.51612
If we subtract 62 from 90, we get 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 12:
280 divided by 31 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 21151.516129
The remainder is 1 after subtracting 279 from 280.
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 13:
The number 31 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 21151.516129
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
31 goes into 100 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 21151.51612903
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 21151.51612903 with a remainder of 7e-09.
