869194 ÷ 19 
The aim is to understand the frequency of 19 in 869194.

Let's proceed to step 1:
If we divide 8 by 19, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 19

Advancing to step 2:
19 can be fit into 86 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 76 from 86 leaves us with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 19

Moving on to step 3:
The number 19 fits into 109 5 times, leaving a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 95 from 109 leaves us with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 19

Step 4:
141 divided by 19 is 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 457.0
The remainder is 8 after subtracting 133 from 141.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 19

Going ahead to step 5:
19 can be fit into 89 4 times, resulting in a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4574.0
If we take 76 away from 89, we end up with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 19

Let's proceed to step 6:
19 goes into 134 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 45747.0
Deduct 133 from 134 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.

Going ahead to step 7:
If we divide 10 by 19, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 45747.0
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.

Going ahead to step 8:
19 goes into 100 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 45747.05
Subtracting 95 from 100 leaves us 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.

On to step 9:
If we divide 50 by 19, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 45747.052
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.

Moving on to step 10:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 45747.0526
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.

Advancing to step 11:
If we divide 60 by 19, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 45747.05263
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
The number 19 fits into 30 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 45747.052631
If we take 19 away from 30, we end up 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.

Going ahead to step 13:
19 can be fit into 110 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 45747.0526315
The remainder is 15 after subtracting 95 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
The number 19 fits into 150 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 45747.05263157
Subtract 133 from 150 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.

After the division, we end up with 45747.05263157 and a remainder of 1.7e-08.
