19208309 divided by 722 
The aim is to understand the frequency of 722 in 19208309.

Step 1:
722 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 722

Advancing to step 2:
The number 722 fits into 19 0 times, leaving a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 722

Going ahead to step 3:
722 can be fit into 192 0 times, resulting in a remainder of 192.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 192 after subtracting 0 from 192.
Grab the next digit (0) from the dividend, add it to 192, then carry on: 1920 / 722

Let's proceed to step 4:
722 can be fit into 1920 2 times, resulting in a remainder of 476.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 476 after subtracting 1444 from 1920.
Include the next digit (8) from the dividend after 476, then repeat: 4768 / 722

On to step 5:
722 can be fit into 4768 6 times, resulting in a remainder of 436.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 436 after subtracting 4332 from 4768.
Take the next digit (3) from the dividend and append it to 436, then repeat: 4363 / 722

Let's proceed to step 6:
If we divide 4363 by 722, we get 6 and a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 266.0
If we take 4332 away from 4363, we end up with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 722

Step 7:
The number 722 fits into 310 0 times, leaving a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 2660.0
If we take 0 away from 310, we end up with 310.
Append the next digit (9) from the dividend to 310 and continue with: 3109 / 722

Advancing to step 8:
3109 divided by 722 is 4 with a remainder of 221.
Write down 4 as next digit of the result. 
Result so far: 26604.0
Subtracting 2888 from 3109 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 9:
2210 divided by 722 is 3 with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 26604.3
If we subtract 2166 from 2210, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
722 can be fit into 440 0 times, resulting in a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 26604.3
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 11:
722 can be fit into 4400 6 times, resulting in a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 26604.306
Deduct 4332 from 4400 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
722 can be fit into 680 0 times, resulting in a remainder of 680.
Use 0 as the next digit of our solution. 
Result so far: 26604.306
Subtract 0 from 680 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 13:
The number 722 fits into 6800 9 times, leaving a remainder of 302.
The number 9 becomes the next digit in our result. 
Result so far: 26604.30609
If we subtract 6498 from 6800, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 14:
3020 divided by 722 is 4 with a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 26604.306094
Subtracting 2888 from 3020 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 15:
722 can be fit into 1320 1 times, resulting in a remainder of 598.
Put 1 as the next digit of the answer. 
Result so far: 26604.3060941
Subtracting 722 from 1320 leaves us with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 16:
When dividing 5980 by 722, we get 8 with a remainder of 204.
The number 8 becomes the next digit in our result. 
Result so far: 26604.30609418
Subtracting 5776 from 5980 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The quotient of the division is 26604.30609418, and the remainder is 2.04e-07.
