We look at the division of 39005336 by 623 
The aim is to understand the frequency of 623 in 39005336.

Moving on to step 1:
3 divided by 623 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 623

Step 2:
623 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 623

Advancing to step 3:
The number 623 fits into 390 0 times, leaving a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 390 and we're left with 390.
Grab the next digit (0) from the dividend, add it to 390, then carry on: 3900 / 623

Moving on to step 4:
When dividing 3900 by 623, we get 6 with a remainder of 162.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 3738 from 3900 to get 162.
Bring next digit (5) of the dividend behind the 162 and repeat the process: 1625 / 623

Going ahead to step 5:
623 can be fit into 1625 2 times, resulting in a remainder of 379.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
Subtract 1246 from 1625 to get 379.
Fetch the next digit (3) from the dividend, attach it to 379 and continue: 3793 / 623

Moving on to step 6:
If we divide 3793 by 623, we get 6 and a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 626.0
Deduct 3738 from 3793 and we're left with 55.
Take the next digit (3) from the dividend and append it to 55, then repeat: 553 / 623

Going ahead to step 7:
623 goes into 553 0 times with a remainder of 553.
Put 0 as the next digit of the answer. 
Result so far: 6260.0
If we take 0 away from 553, we end up with 553.
Fetch the next digit (6) from the dividend, attach it to 553 and continue: 5536 / 623

Let's proceed to step 8:
When dividing 5536 by 623, we get 8 with a remainder of 552.
Put 8 as the next digit of the answer. 
Result so far: 62608.0
If we take 4984 away from 5536, we end up with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 9:
The number 623 fits into 5520 8 times, leaving a remainder of 536.
Put 8 as the next digit of the answer. 
Result so far: 62608.8
Subtracting 4984 from 5520 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 10:
The number 623 fits into 5360 8 times, leaving a remainder of 376.
Use 8 as the next digit of our solution. 
Result so far: 62608.88
If we take 4984 away from 5360, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final result is 62608.88 with a remainder of 0.376.
