We look at the division of 19096814 by 31 
The aim is to understand the frequency of 31 in 19096814.

On to step 1:
The number 31 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 31

Going ahead to step 2:
31 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 31

Advancing to step 3:
When dividing 190 by 31, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 186 away from 190, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 31

Advancing to step 4:
The number 31 fits into 49 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
The remainder is 18 after subtracting 31 from 49.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 31

On to step 5:
31 goes into 186 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 616.0
If we subtract 186 from 186, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 31

Advancing to step 6:
8 divided by 31 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 6160.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 31

On to step 7:
If we divide 81 by 31, we get 2 and a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 61602.0
Subtract 62 from 81 to get 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 31

Step 8:
When dividing 194 by 31, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 616026.0
If we subtract 186 from 194, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
31 goes into 80 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 616026.2
Subtracting 62 from 80 leaves us 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.

Moving on to step 10:
180 divided by 31 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 616026.25
If we take 155 away from 180, we end up 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.

Going ahead to step 11:
250 divided by 31 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 616026.258
Deduct 248 from 250 and we're left 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.

Advancing to step 12:
If we divide 20 by 31, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 616026.258
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.

Advancing to step 13:
31 can be fit into 200 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 616026.25806
Deduct 186 from 200 and we're left 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.

On to step 14:
140 divided by 31 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 616026.258064
The remainder is 16 after subtracting 124 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 15:
160 divided by 31 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 616026.2580645
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.

Advancing to step 16:
If we divide 50 by 31, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 616026.25806451
Deduct 31 from 50 and we're left 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.

The quotient of the division is 616026.25806451, and the remainder is 1.9e-08.
