We're dividing 6762895 by 621 
The aim is to understand the frequency of 621 in 6762895.

Step 1:
6 divided by 621 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 621

Moving on to step 2:
The number 621 fits into 67 0 times, leaving a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Append the next digit (6) from the dividend to 67 and continue with: 676 / 621

Let's proceed to step 3:
621 goes into 676 1 times with a remainder of 55.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 621 from 676 and we're left with 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 621

Advancing to step 4:
621 goes into 552 0 times with a remainder of 552.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 552 leaves us with 552.
Append the next digit (8) from the dividend to 552 and continue with: 5528 / 621

Going ahead to step 5:
The number 621 fits into 5528 8 times, leaving a remainder of 560.
Write down 8 as next digit of the result. 
Result so far: 108.0
Deduct 4968 from 5528 and we're left with 560.
Take the next digit (9) from the dividend and append it to 560, then repeat: 5609 / 621

Advancing to step 6:
When dividing 5609 by 621, we get 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 1089.0
Subtracting 5589 from 5609 leaves us with 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 621

Let's proceed to step 7:
The number 621 fits into 205 0 times, leaving a remainder of 205.
The number 0 becomes the next digit in our result. 
Result so far: 10890.0
The remainder is 205 after subtracting 0 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 8:
2050 divided by 621 is 3 with a remainder of 187.
Record the quotient 3 as the next digit in the result. 
Result so far: 10890.3
If we subtract 1863 from 2050, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 9:
621 can be fit into 1870 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 10890.33
If we subtract 1863 from 1870, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 10890.33 with a balance of 0.007.
