We divide 548286 by 31
The aim is to understand the frequency of 31 in 548286.

Advancing to step 1:
When dividing 5 by 31, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 31

On to step 2:
31 goes into 54 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 23 after subtracting 31 from 54.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 31

Step 3:
238 divided by 31 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 21 after subtracting 217 from 238.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 31

Let's proceed to step 4:
If we divide 212 by 31, we get 6 and a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 176.0
If we take 186 away from 212, we end up with 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 31

Let's proceed to step 5:
The number 31 fits into 268 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 1768.0
If we take 248 away from 268, we end up with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 31

Advancing to step 6:
The number 31 fits into 206 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 17686.0
Deduct 186 from 206 and we're left 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.

Going ahead to step 7:
The number 31 fits into 200 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 17686.6
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 8:
140 divided by 31 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 17686.64
If we subtract 124 from 140, we get 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 9:
31 goes into 160 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 17686.645
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.

Let's proceed to step 10:
31 goes into 50 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 17686.6451
The remainder is 19 after subtracting 31 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
31 goes into 190 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 17686.64516
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.

Moving on to step 12:
40 divided by 31 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 17686.645161
Subtract 31 from 40 to get 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 13:
31 can be fit into 90 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 17686.6451612
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.

Going ahead to step 14:
31 goes into 280 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 17686.64516129
If we take 279 away from 280, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 17686.64516129 and a remainder of 1e-09.
