Let's divide 46902736 by 621
The aim is to understand the frequency of 621 in 46902736.

Going ahead to step 1:
The number 621 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 621

Moving on to step 2:
The number 621 fits into 46 0 times, leaving a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 46 and we're left with 46.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 621

Step 3:
621 goes into 469 0 times with a remainder of 469.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 469 after subtracting 0 from 469.
Include the next digit (0) from the dividend after 469, then repeat: 4690 / 621

Step 4:
621 can be fit into 4690 7 times, resulting in a remainder of 343.
The next digit of our result is 7. 
Result so far: 7.0
If we take 4347 away from 4690, we end up with 343.
Take the next digit (2) from the dividend and append it to 343, then repeat: 3432 / 621

On to step 5:
When dividing 3432 by 621, we get 5 with a remainder of 327.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we take 3105 away from 3432, we end up with 327.
Take the next digit (7) from the dividend and append it to 327, then repeat: 3277 / 621

Step 6:
621 can be fit into 3277 5 times, resulting in a remainder of 172.
Use 5 as the next digit of our solution. 
Result so far: 755.0
Subtract 3105 from 3277 to get 172.
Include the next digit (3) from the dividend after 172, then repeat: 1723 / 621

Going ahead to step 7:
1723 divided by 621 is 2 with a remainder of 481.
Use 2 as the next digit of our solution. 
Result so far: 7552.0
If we subtract 1242 from 1723, we get 481.
Fetch the next digit (6) from the dividend, attach it to 481 and continue: 4816 / 621

Going ahead to step 8:
The number 621 fits into 4816 7 times, leaving a remainder of 469.
Write down 7 as next digit of the result. 
Result so far: 75527.0
Deduct 4347 from 4816 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.

On to step 9:
621 can be fit into 4690 7 times, resulting in a remainder of 343.
Write down 7 as next digit of the result. 
Result so far: 75527.7
If we take 4347 away from 4690, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

On to step 10:
3430 divided by 621 is 5 with a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 75527.75
The remainder is 325 after subtracting 3105 from 3430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 11:
The number 621 fits into 3250 5 times, leaving a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 75527.755
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.

The final result is 75527.755 with a remainder of 0.0145.
