We look at the division of 90834 by 19 
The aim is to understand the frequency of 19 in 90834.

On to step 1:
If we divide 9 by 19, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 19

Advancing to step 2:
The number 19 fits into 90 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 76 away from 90, we end up with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 19

Advancing to step 3:
When dividing 148 by 19, we get 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Deduct 133 from 148 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 19

Moving on to step 4:
If we divide 153 by 19, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 478.0
If we subtract 152 from 153, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 19

Going ahead to step 5:
When dividing 14 by 19, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 4780.0
The remainder is 14 after subtracting 0 from 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 6:
If we divide 140 by 19, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 4780.7
Subtract 133 from 140 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 19 is 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 4780.73
If we take 57 away from 70, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
19 goes into 130 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 4780.736
If we take 114 away from 130, we end up 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.

Let's proceed to step 9:
160 divided by 19 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 4780.7368
Subtracting 152 from 160 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4780.73684
Subtracting 76 from 80 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:
19 goes into 40 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 4780.736842
If we subtract 38 from 40, we get 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 12:
The number 19 fits into 20 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 4780.7368421
Deduct 19 from 20 and we're left 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.

On to step 13:
10 divided by 19 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4780.7368421
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.

After the division, we end up with 4780.7368421 and a remainder of 1e-08.
