Let's divide 64413898 by 19
The aim is to understand the frequency of 19 in 64413898.

Let's proceed to step 1:
When dividing 6 by 19, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 19

Going ahead to step 2:
If we divide 64 by 19, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 57 from 64, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 19

Let's proceed to step 3:
74 divided by 19 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 57 from 74 and we're left with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 19

Step 4:
19 can be fit into 171 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 339.0
The remainder is 0 after subtracting 171 from 171.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 19

Step 5:
19 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 3390.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 19

Advancing to step 6:
When dividing 38 by 19, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 33902.0
The remainder is 0 after subtracting 38 from 38.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 19

Step 7:
When dividing 9 by 19, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 339020.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 19

On to step 8:
19 can be fit into 98 5 times, resulting in a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 3390205.0
If we take 95 away from 98, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
When dividing 30 by 19, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 3390205.1
If we subtract 19 from 30, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
19 can be fit into 110 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 3390205.15
Subtracting 95 from 110 leaves us with 15.
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 11:
19 goes into 150 7 times with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 3390205.157
Deduct 133 from 150 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
When dividing 170 by 19, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 3390205.1578
Subtract 152 from 170 to 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 13:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 3390205.15789
Subtracting 171 from 180 leaves us with 9.
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 14:
90 divided by 19 is 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 3390205.157894
Deduct 76 from 90 and we're left 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.

Step 15:
When dividing 140 by 19, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 3390205.1578947
Deduct 133 from 140 and we're left 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.

Going ahead to step 16:
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: 3390205.15789473
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 3390205.15789473 with a remainder of 1.3e-08.
