634881 ÷ 19 
The aim is to understand the frequency of 19 in 634881.

Let's proceed to step 1:
6 divided by 19 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 19

Step 2:
19 can be fit into 63 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 57 away from 63, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 19

Advancing to step 3:
When dividing 64 by 19, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 33.0
The remainder is 7 after subtracting 57 from 64.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 19

On to step 4:
If we divide 78 by 19, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 334.0
Subtract 76 from 78 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 19

Advancing to step 5:
When dividing 28 by 19, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 3341.0
If we subtract 19 from 28, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 19

Step 6:
If we divide 91 by 19, we get 4 and a remainder of 15.
The next digit of our result is 4. 
Result so far: 33414.0
Deduct 76 from 91 and we're left 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.

Advancing to step 7:
The number 19 fits into 150 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 33414.7
The remainder is 17 after subtracting 133 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
If we divide 170 by 19, we get 8 and a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 33414.78
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.

On to step 9:
When dividing 180 by 19, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 33414.789
If we subtract 171 from 180, we get 9.
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 10:
19 goes into 90 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 33414.7894
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.

Going ahead to step 11:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 33414.78947
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.

On to step 12:
The number 19 fits into 70 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 33414.789473
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 13:
The number 19 fits into 130 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 33414.7894736
Subtract 114 from 130 to get 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 14:
19 can be fit into 160 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 33414.78947368
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.

The final outcome is 33414.78947368, with a leftover of 8e-09.
