33227287 divided by 621 
The aim is to understand the frequency of 621 in 33227287.

On to step 1:
When dividing 3 by 621, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 621

Moving on to step 2:
33 divided by 621 is 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Append the next digit (2) from the dividend to 33 and continue with: 332 / 621

Advancing to step 3:
621 goes into 332 0 times with a remainder of 332.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 332 to get 332.
Take the next digit (2) from the dividend and append it to 332, then repeat: 3322 / 621

Advancing to step 4:
The number 621 fits into 3322 5 times, leaving a remainder of 217.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 3105 from 3322 leaves us with 217.
Append the next digit (7) from the dividend to 217 and continue with: 2177 / 621

Advancing to step 5:
When dividing 2177 by 621, we get 3 with a remainder of 314.
Write down 3 as next digit of the result. 
Result so far: 53.0
The remainder is 314 after subtracting 1863 from 2177.
Take the next digit (2) from the dividend and append it to 314, then repeat: 3142 / 621

Let's proceed to step 6:
When dividing 3142 by 621, we get 5 with a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 535.0
If we take 3105 away from 3142, we end up with 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 621

Moving on to step 7:
378 divided by 621 is 0 with a remainder of 378.
The number 0 becomes the next digit in our result. 
Result so far: 5350.0
Deduct 0 from 378 and we're left with 378.
Grab the next digit (7) from the dividend, add it to 378, then carry on: 3787 / 621

Moving on to step 8:
621 goes into 3787 6 times with a remainder of 61.
Record the quotient 6 as the next digit in the result. 
Result so far: 53506.0
Subtract 3726 from 3787 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
If we divide 610 by 621, we get 0 and a remainder of 610.
Write down 0 as next digit of the result. 
Result so far: 53506.0
Subtracting 0 from 610 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 10:
6100 divided by 621 is 9 with a remainder of 511.
Record the quotient 9 as the next digit in the result. 
Result so far: 53506.09
Deduct 5589 from 6100 and we're left with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Going ahead to step 11:
The number 621 fits into 5110 8 times, leaving a remainder of 142.
The next digit of our result is 8. 
Result so far: 53506.098
If we subtract 4968 from 5110, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 12:
621 can be fit into 1420 2 times, resulting in a remainder of 178.
The next digit of our result is 2. 
Result so far: 53506.0982
Subtracting 1242 from 1420 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 13:
621 can be fit into 1780 2 times, resulting in a remainder of 538.
Write down 2 as next digit of the result. 
Result so far: 53506.09822
If we subtract 1242 from 1780, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

In conclusion, the division gives 53506.09822 with a balance of 0.000538.
