275980 ÷ 31 
The aim is to understand the frequency of 31 in 275980.

Going ahead to step 1:
31 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 31

Going ahead to step 2:
31 goes into 27 0 times with a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 31

Let's proceed to step 3:
31 goes into 275 8 times with a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 248 from 275, we get 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 31

Going ahead to step 4:
31 goes into 279 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 89.0
The remainder is 0 after subtracting 279 from 279.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 31

Going ahead to step 5:
When dividing 8 by 31, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 890.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 31

Moving on to step 6:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 8902.0
If we subtract 62 from 80, we get 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 7:
The number 31 fits into 180 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 8902.5
Subtracting 155 from 180 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
If we divide 250 by 31, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8902.58
The remainder is 2 after subtracting 248 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
20 divided by 31 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 8902.58
If we take 0 away from 20, we end up 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.

Moving on to step 10:
31 can be fit into 200 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 8902.5806
Subtracting 186 from 200 leaves us 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.

Advancing to step 11:
When dividing 140 by 31, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 8902.58064
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 12:
When dividing 160 by 31, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 8902.580645
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.

Going ahead to step 13:
If we divide 50 by 31, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 8902.5806451
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.

Going ahead to step 14:
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: 8902.58064516
Deduct 186 from 190 and we're left 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.

The quotient of the division is 8902.58064516, and the remainder is 4e-09.
