We look at the division of 30670 by 19 
The aim is to understand the frequency of 19 in 30670.

Step 1:
3 divided by 19 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 19

Step 2:
19 can be fit into 30 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 11 after subtracting 19 from 30.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 19

On to step 3:
If we divide 116 by 19, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 2 after subtracting 114 from 116.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 19

Moving on to step 4:
The number 19 fits into 27 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
If we take 19 away from 27, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 19

Moving on to step 5:
80 divided by 19 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 1614.0
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 6:
19 goes into 40 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 1614.2
Deduct 38 from 40 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.

On to step 7:
When dividing 20 by 19, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1614.21
If we subtract 19 from 20, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
When dividing 10 by 19, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1614.21
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
If we divide 100 by 19, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1614.2105
Subtract 95 from 100 to 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.

Let's proceed to step 10:
19 can be fit into 50 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 1614.21052
Deduct 38 from 50 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
120 divided by 19 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 1614.210526
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
The number 19 fits into 60 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 1614.2105263
If we take 57 away from 60, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
30 divided by 19 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1614.21052631
Subtracting 19 from 30 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 1614.21052631 with a remaining 1.1e-08.
