689128 ÷ 19 
The aim is to understand the frequency of 19 in 689128.

On to step 1:
19 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 19

Going ahead to step 2:
19 can be fit into 68 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 57 away from 68, we end up with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 19

On to step 3:
119 divided by 19 is 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 114 from 119 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 19

Going ahead to step 4:
If we divide 51 by 19, we get 2 and a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
Subtracting 38 from 51 leaves us with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 19

Going ahead to step 5:
132 divided by 19 is 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 3626.0
If we subtract 114 from 132, we get 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 19

Moving on to step 6:
19 goes into 188 9 times with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 36269.0
Subtract 171 from 188 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
When dividing 170 by 19, we get 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 36269.8
If we subtract 152 from 170, we get 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 8:
19 goes into 180 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 36269.89
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
If we divide 90 by 19, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 36269.894
Subtract 76 from 90 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.

On to step 10:
When dividing 140 by 19, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 36269.8947
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 11:
If we divide 70 by 19, we get 3 and a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 36269.89473
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.

Step 12:
19 goes into 130 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 36269.894736
Subtracting 114 from 130 leaves us 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 13:
If we divide 160 by 19, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 36269.8947368
Deduct 152 from 160 and we're left 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.

Going ahead to step 14:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 36269.89473684
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.

The final outcome is 36269.89473684, with a leftover of 4e-09.
