Let's divide 789086 by 19
The aim is to understand the frequency of 19 in 789086.

Step 1:
19 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 19

On to step 2:
78 divided by 19 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 2 after subtracting 76 from 78.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 19

Going ahead to step 3:
If we divide 29 by 19, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 41.0
If we subtract 19 from 29, we get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 19

Step 4:
100 divided by 19 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 415.0
If we take 95 away from 100, we end up with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 19

Advancing to step 5:
The number 19 fits into 58 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 4153.0
Subtract 57 from 58 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 19

Step 6:
16 divided by 19 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 41530.0
Subtract 0 from 16 to 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.

Step 7:
19 goes into 160 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 41530.8
Subtract 152 from 160 to 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.

On to step 8:
If we divide 80 by 19, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 41530.84
Deduct 76 from 80 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.

Step 9:
If we divide 40 by 19, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 41530.842
If we take 38 away from 40, we end up 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 10:
When dividing 20 by 19, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 41530.8421
Subtracting 19 from 20 leaves us 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 11:
19 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 41530.8421
Subtracting 0 from 10 leaves us 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 12:
When dividing 100 by 19, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 41530.842105
If we take 95 away from 100, 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.

Moving on to step 13:
19 goes into 50 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 41530.8421052
If we take 38 away from 50, we end up 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.

On to step 14:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 41530.84210526
Subtract 114 from 120 to 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.

After the division, we end up with 41530.84210526 and a remainder of 6e-09.
