17272778 ÷ 623 
The aim is to understand the frequency of 623 in 17272778.

Moving on to step 1:
623 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 623

Let's proceed to step 2:
17 divided by 623 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 623

Going ahead to step 3:
If we divide 172 by 623, we get 0 and a remainder of 172.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 172, we end up with 172.
Take the next digit (7) from the dividend and append it to 172, then repeat: 1727 / 623

Going ahead to step 4:
623 can be fit into 1727 2 times, resulting in a remainder of 481.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1246 from 1727 leaves us with 481.
Grab the next digit (2) from the dividend, add it to 481, then carry on: 4812 / 623

Moving on to step 5:
If we divide 4812 by 623, we get 7 and a remainder of 451.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 4361 from 4812 and we're left with 451.
Grab the next digit (7) from the dividend, add it to 451, then carry on: 4517 / 623

Advancing to step 6:
If we divide 4517 by 623, we get 7 and a remainder of 156.
Put 7 as the next digit of the answer. 
Result so far: 277.0
Deduct 4361 from 4517 and we're left with 156.
Fetch the next digit (7) from the dividend, attach it to 156 and continue: 1567 / 623

Moving on to step 7:
623 can be fit into 1567 2 times, resulting in a remainder of 321.
The number 2 becomes the next digit in our result. 
Result so far: 2772.0
Subtract 1246 from 1567 to get 321.
Take the next digit (8) from the dividend and append it to 321, then repeat: 3218 / 623

On to step 8:
If we divide 3218 by 623, we get 5 and a remainder of 103.
The next digit of our result is 5. 
Result so far: 27725.0
Subtracting 3115 from 3218 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 9:
If we divide 1030 by 623, we get 1 and a remainder of 407.
Write down 1 as next digit of the result. 
Result so far: 27725.1
The remainder is 407 after subtracting 623 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Advancing to step 10:
If we divide 4070 by 623, we get 6 and a remainder of 332.
Use 6 as the next digit of our solution. 
Result so far: 27725.16
Subtract 3738 from 4070 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Let's proceed to step 11:
623 goes into 3320 5 times with a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 27725.165
Subtracting 3115 from 3320 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 12:
The number 623 fits into 2050 3 times, leaving a remainder of 181.
Record the quotient 3 as the next digit in the result. 
Result so far: 27725.1653
Subtract 1869 from 2050 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Step 13:
1810 divided by 623 is 2 with a remainder of 564.
The number 2 becomes the next digit in our result. 
Result so far: 27725.16532
If we subtract 1246 from 1810, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 14:
When dividing 5640 by 623, we get 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 27725.165329
If we subtract 5607 from 5640, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 15:
623 goes into 330 0 times with a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 27725.165329
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 16:
The number 623 fits into 3300 5 times, leaving a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 27725.16532905
If we take 3115 away from 3300, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

The final outcome is 27725.16532905, with a leftover of 1.85e-07.
