Let's divide 778993 by 19
The aim is to understand the frequency of 19 in 778993.

Advancing to step 1:
19 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 19

Moving on to step 2:
If we divide 77 by 19, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 76 from 77, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 19

Going ahead to step 3:
If we divide 18 by 19, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 40.0
The remainder is 18 after subtracting 0 from 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 19

On to step 4:
When dividing 189 by 19, we get 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 409.0
Deduct 171 from 189 and we're left with 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 19

On to step 5:
The number 19 fits into 189 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 4099.0
Subtract 171 from 189 to get 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 19

On to step 6:
If we divide 183 by 19, we get 9 and a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 40999.0
Deduct 171 from 183 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 7:
19 goes into 120 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 40999.6
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.

On to step 8:
The number 19 fits into 60 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 40999.63
Subtract 57 from 60 to 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.

Step 9:
If we divide 30 by 19, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 40999.631
Deduct 19 from 30 and we're left 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.

Moving on to step 10:
If we divide 110 by 19, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 40999.6315
Subtract 95 from 110 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
When dividing 150 by 19, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 40999.63157
Subtracting 133 from 150 leaves us 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.

Let's proceed to step 12:
The number 19 fits into 170 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 40999.631578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
If we divide 180 by 19, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 40999.6315789
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 14:
The number 19 fits into 90 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 40999.63157894
Subtract 76 from 90 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 40999.63157894 and a remainder of 1.4e-08.
