We divide 490031 by 31
The aim is to understand the frequency of 31 in 490031.

Moving on to step 1:
When dividing 4 by 31, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 31

Moving on to step 2:
49 divided by 31 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 31 from 49 and we're left with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 31

On to step 3:
180 divided by 31 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 155 from 180 to get 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 31

Moving on to step 4:
31 goes into 250 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 158.0
If we subtract 248 from 250, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 31

Going ahead to step 5:
23 divided by 31 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 1580.0
The remainder is 23 after subtracting 0 from 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 31

On to step 6:
31 goes into 231 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 15807.0
Subtract 217 from 231 to get 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 7:
The number 31 fits into 140 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 15807.4
Deduct 124 from 140 and we're left 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 8:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15807.45
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 9:
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: 15807.451
Subtracting 31 from 50 leaves us 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 10:
190 divided by 31 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 15807.4516
Subtracting 186 from 190 leaves us 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.

Advancing to step 11:
The number 31 fits into 40 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 15807.45161
Deduct 31 from 40 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
31 can be fit into 90 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 15807.451612
Subtracting 62 from 90 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
If we divide 280 by 31, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 15807.4516129
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.

Going ahead to step 14:
31 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 15807.4516129
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.

In conclusion, the division gives 15807.4516129 with a balance of 1e-08.
