50633483 ÷ 521 
The aim is to understand the frequency of 521 in 50633483.

Going ahead to step 1:
The number 521 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 521

Advancing to step 2:
521 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Fetch the next digit (6) from the dividend, attach it to 50 and continue: 506 / 521

Advancing to step 3:
The number 521 fits into 506 0 times, leaving a remainder of 506.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 506 after subtracting 0 from 506.
Bring next digit (3) of the dividend behind the 506 and repeat the process: 5063 / 521

Let's proceed to step 4:
The number 521 fits into 5063 9 times, leaving a remainder of 374.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 4689 from 5063 to get 374.
Take the next digit (3) from the dividend and append it to 374, then repeat: 3743 / 521

Step 5:
If we divide 3743 by 521, we get 7 and a remainder of 96.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtracting 3647 from 3743 leaves us with 96.
Take the next digit (4) from the dividend and append it to 96, then repeat: 964 / 521

Advancing to step 6:
When dividing 964 by 521, we get 1 with a remainder of 443.
Write down 1 as next digit of the result. 
Result so far: 971.0
If we take 521 away from 964, we end up with 443.
Fetch the next digit (8) from the dividend, attach it to 443 and continue: 4438 / 521

Let's proceed to step 7:
The number 521 fits into 4438 8 times, leaving a remainder of 270.
Put 8 as the next digit of the answer. 
Result so far: 9718.0
Subtracting 4168 from 4438 leaves us with 270.
Take the next digit (3) from the dividend and append it to 270, then repeat: 2703 / 521

Let's proceed to step 8:
521 can be fit into 2703 5 times, resulting in a remainder of 98.
Put 5 as the next digit of the answer. 
Result so far: 97185.0
Subtracting 2605 from 2703 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 9:
When dividing 980 by 521, we get 1 with a remainder of 459.
The next digit of our result is 1. 
Result so far: 97185.1
Subtract 521 from 980 to get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Let's proceed to step 10:
4590 divided by 521 is 8 with a remainder of 422.
The next digit of our result is 8. 
Result so far: 97185.18
The remainder is 422 after subtracting 4168 from 4590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 11:
The number 521 fits into 4220 8 times, leaving a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 97185.188
If we subtract 4168 from 4220, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 97185.188 and a remainder of 0.0052.
