763448 divided by 19 
The aim is to understand the frequency of 19 in 763448.

Let's proceed to step 1:
The number 19 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 19

On to step 2:
19 goes into 76 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 0 after subtracting 76 from 76.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 19

Going ahead to step 3:
The number 19 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 3 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 19

Going ahead to step 4:
34 divided by 19 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 401.0
If we subtract 19 from 34, we get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 19

On to step 5:
19 can be fit into 154 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 4018.0
The remainder is 2 after subtracting 152 from 154.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 19

Going ahead to step 6:
19 goes into 28 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 40181.0
Deduct 19 from 28 and we're left 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.

Step 7:
19 goes into 90 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 40181.4
If we take 76 away from 90, we end up 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.

Moving on to step 8:
If we divide 140 by 19, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 40181.47
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.

Step 9:
19 can be fit into 70 3 times, resulting in a remainder of 13.
The next digit of our result is 3. 
Result so far: 40181.473
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.

On to step 10:
If we divide 130 by 19, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 40181.4736
Deduct 114 from 130 and we're left 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.

Let's proceed to step 11:
When dividing 160 by 19, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 40181.47368
Deduct 152 from 160 and we're left 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 12:
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: 40181.473684
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 13:
19 goes into 40 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 40181.4736842
If we subtract 38 from 40, we 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.

On to step 14:
19 can be fit into 20 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 40181.47368421
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.

The final result is 40181.47368421 with a remainder of 1e-09.
