73795487 divided by 521 
The aim is to understand the frequency of 521 in 73795487.

Let's proceed to step 1:
7 divided by 521 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 521

Advancing to step 2:
73 divided by 521 is 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Grab the next digit (7) from the dividend, add it to 73, then carry on: 737 / 521

Going ahead to step 3:
521 can be fit into 737 1 times, resulting in a remainder of 216.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 216 after subtracting 521 from 737.
Fetch the next digit (9) from the dividend, attach it to 216 and continue: 2169 / 521

Let's proceed to step 4:
If we divide 2169 by 521, we get 4 and a remainder of 85.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 2084 from 2169, we get 85.
Fetch the next digit (5) from the dividend, attach it to 85 and continue: 855 / 521

Let's proceed to step 5:
When dividing 855 by 521, we get 1 with a remainder of 334.
Put 1 as the next digit of the answer. 
Result so far: 141.0
If we take 521 away from 855, we end up with 334.
Grab the next digit (4) from the dividend, add it to 334, then carry on: 3344 / 521

Going ahead to step 6:
If we divide 3344 by 521, we get 6 and a remainder of 218.
The next digit of our result is 6. 
Result so far: 1416.0
Subtract 3126 from 3344 to get 218.
Take the next digit (8) from the dividend and append it to 218, then repeat: 2188 / 521

Going ahead to step 7:
The number 521 fits into 2188 4 times, leaving a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 14164.0
If we take 2084 away from 2188, we end up with 104.
Take the next digit (7) from the dividend and append it to 104, then repeat: 1047 / 521

Moving on to step 8:
When dividing 1047 by 521, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 141642.0
If we subtract 1042 from 1047, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
521 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 141642.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 521 fits into 500 0 times, leaving a remainder of 500.
The next digit of our result is 0. 
Result so far: 141642.0
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 141642.0, with a leftover of 0.5.
