Let's divide 43432859 by 19
The aim is to understand the frequency of 19 in 43432859.

Let's proceed to step 1:
19 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 19

Advancing to step 2:
43 divided by 19 is 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 38 from 43, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 19

Going ahead to step 3:
19 can be fit into 54 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we take 38 away from 54, we end up with 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 19

Advancing to step 4:
When dividing 163 by 19, we get 8 with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 228.0
If we subtract 152 from 163, we get 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 19

Going ahead to step 5:
If we divide 112 by 19, we get 5 and a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 2285.0
Subtract 95 from 112 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 19

Advancing to step 6:
178 divided by 19 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 22859.0
The remainder is 7 after subtracting 171 from 178.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 19

On to step 7:
The number 19 fits into 75 3 times, leaving a remainder of 18.
The next digit of our result is 3. 
Result so far: 228593.0
If we take 57 away from 75, we end up with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 19

Moving on to step 8:
When dividing 189 by 19, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 2285939.0
Subtracting 171 from 189 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 2285939.9
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 10:
If we divide 90 by 19, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 2285939.94
Subtracting 76 from 90 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
19 goes into 140 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 2285939.947
Subtracting 133 from 140 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
If we divide 70 by 19, we get 3 and a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 2285939.9473
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
If we divide 130 by 19, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 2285939.94736
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.

Step 14:
160 divided by 19 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 2285939.947368
If we take 152 away from 160, we end up 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 15:
If we divide 80 by 19, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 2285939.9473684
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.

On to step 16:
19 goes into 40 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2285939.94736842
Subtract 38 from 40 to 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.

The final outcome is 2285939.94736842, with a leftover of 2e-09.
