Let's divide 751628 by 19
The aim is to understand the frequency of 19 in 751628.

Step 1:
If we divide 7 by 19, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 19

Let's proceed to step 2:
19 can be fit into 75 3 times, resulting in a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 18 after subtracting 57 from 75.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 19

Going ahead to step 3:
If we divide 181 by 19, we get 9 and a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 10 after subtracting 171 from 181.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 19

Going ahead to step 4:
If we divide 106 by 19, we get 5 and a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 395.0
Subtract 95 from 106 to get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 19

On to step 5:
The number 19 fits into 112 5 times, leaving a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 3955.0
Subtract 95 from 112 to get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 19

Going ahead to step 6:
19 goes into 178 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 39559.0
If we subtract 171 from 178, we 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.

Let's proceed to step 7:
70 divided by 19 is 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 39559.3
Deduct 57 from 70 and we're left 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.

On to step 8:
130 divided by 19 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 39559.36
The remainder is 16 after subtracting 114 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
19 goes into 160 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 39559.368
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 39559.3684
Deduct 76 from 80 and we're left 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 can be fit into 40 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 39559.36842
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.

Step 12:
19 goes into 20 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 39559.368421
Subtract 19 from 20 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 39559.368421
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
100 divided by 19 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 39559.36842105
The remainder is 5 after subtracting 95 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 39559.36842105 with a remainder of 5e-09.
