We're dividing 775121 by 19 
The aim is to understand the frequency of 19 in 775121.

Let's proceed to step 1:
19 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 19

Step 2:
19 goes into 77 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 1 after subtracting 76 from 77.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 19

Going ahead to step 3:
If we divide 15 by 19, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 15 to get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 19

Advancing to step 4:
When dividing 151 by 19, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 407.0
Deduct 133 from 151 and we're left with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 19

Let's proceed to step 5:
19 can be fit into 182 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 4079.0
If we take 171 away from 182, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 19

Step 6:
19 can be fit into 111 5 times, resulting in a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 40795.0
If we take 95 away from 111, 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.

On to step 7:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 40795.8
Subtracting 152 from 160 leaves us 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.

Advancing to step 8:
The number 19 fits into 80 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 40795.84
If we take 76 away from 80, we end up 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 9:
The number 19 fits into 40 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 40795.842
If we take 38 away from 40, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
If we divide 20 by 19, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 40795.8421
The remainder is 1 after subtracting 19 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
19 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 40795.8421
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.

Moving on to step 12:
If we divide 100 by 19, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 40795.842105
If we subtract 95 from 100, we get 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 13:
When dividing 50 by 19, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 40795.8421052
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.

Let's proceed to step 14:
120 divided by 19 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 40795.84210526
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 40795.84210526, and the remainder is 6e-09.
