40933324 divided by 621 
The aim is to understand the frequency of 621 in 40933324.

On to step 1:
621 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 621

Advancing to step 2:
If we divide 40 by 621, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 621

On to step 3:
The number 621 fits into 409 0 times, leaving a remainder of 409.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 409 leaves us with 409.
Include the next digit (3) from the dividend after 409, then repeat: 4093 / 621

Advancing to step 4:
621 goes into 4093 6 times with a remainder of 367.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 3726 from 4093, we get 367.
Include the next digit (3) from the dividend after 367, then repeat: 3673 / 621

On to step 5:
When dividing 3673 by 621, we get 5 with a remainder of 568.
Write down 5 as next digit of the result. 
Result so far: 65.0
Deduct 3105 from 3673 and we're left with 568.
Take the next digit (3) from the dividend and append it to 568, then repeat: 5683 / 621

Let's proceed to step 6:
621 can be fit into 5683 9 times, resulting in a remainder of 94.
Write down 9 as next digit of the result. 
Result so far: 659.0
Deduct 5589 from 5683 and we're left with 94.
Bring next digit (2) of the dividend behind the 94 and repeat the process: 942 / 621

Going ahead to step 7:
621 goes into 942 1 times with a remainder of 321.
Write down 1 as next digit of the result. 
Result so far: 6591.0
If we subtract 621 from 942, we get 321.
Fetch the next digit (4) from the dividend, attach it to 321 and continue: 3214 / 621

Moving on to step 8:
3214 divided by 621 is 5 with a remainder of 109.
The next digit of our result is 5. 
Result so far: 65915.0
Subtracting 3105 from 3214 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 9:
621 can be fit into 1090 1 times, resulting in a remainder of 469.
Use 1 as the next digit of our solution. 
Result so far: 65915.1
Deduct 621 from 1090 and we're left with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Moving on to step 10:
If we divide 4690 by 621, we get 7 and a remainder of 343.
The next digit of our result is 7. 
Result so far: 65915.17
The remainder is 343 after subtracting 4347 from 4690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 11:
3430 divided by 621 is 5 with a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 65915.175
Deduct 3105 from 3430 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 12:
If we divide 3250 by 621, we get 5 and a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 65915.1755
If we subtract 3105 from 3250, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

After the division, we end up with 65915.1755 and a remainder of 0.00145.
