We divide 29192931 by 521
The aim is to understand the frequency of 521 in 29192931.

On to step 1:
When dividing 2 by 521, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 521

Advancing to step 2:
If we divide 29 by 521, we get 0 and a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 521

Step 3:
291 divided by 521 is 0 with a remainder of 291.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 291 after subtracting 0 from 291.
Grab the next digit (9) from the dividend, add it to 291, then carry on: 2919 / 521

Moving on to step 4:
The number 521 fits into 2919 5 times, leaving a remainder of 314.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 2605 from 2919 to get 314.
Take the next digit (2) from the dividend and append it to 314, then repeat: 3142 / 521

Let's proceed to step 5:
If we divide 3142 by 521, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Subtracting 3126 from 3142 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 521

Let's proceed to step 6:
521 goes into 169 0 times with a remainder of 169.
Use 0 as the next digit of our solution. 
Result so far: 560.0
Subtract 0 from 169 to get 169.
Grab the next digit (3) from the dividend, add it to 169, then carry on: 1693 / 521

Going ahead to step 7:
1693 divided by 521 is 3 with a remainder of 130.
Record the quotient 3 as the next digit in the result. 
Result so far: 5603.0
Subtract 1563 from 1693 to get 130.
Take the next digit (1) from the dividend and append it to 130, then repeat: 1301 / 521

Moving on to step 8:
1301 divided by 521 is 2 with a remainder of 259.
Write down 2 as next digit of the result. 
Result so far: 56032.0
The remainder is 259 after subtracting 1042 from 1301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Step 9:
521 can be fit into 2590 4 times, resulting in a remainder of 506.
Record the quotient 4 as the next digit in the result. 
Result so far: 56032.4
Deduct 2084 from 2590 and we're left with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Advancing to step 10:
521 goes into 5060 9 times with a remainder of 371.
The number 9 becomes the next digit in our result. 
Result so far: 56032.49
Deduct 4689 from 5060 and we're left with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 11:
If we divide 3710 by 521, we get 7 and a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 56032.497
If we take 3647 away from 3710, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 12:
521 goes into 630 1 times with a remainder of 109.
Use 1 as the next digit of our solution. 
Result so far: 56032.4971
Subtract 521 from 630 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 13:
521 can be fit into 1090 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 56032.49712
Deduct 1042 from 1090 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
If we divide 480 by 521, we get 0 and a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 56032.49712
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 15:
The number 521 fits into 4800 9 times, leaving a remainder of 111.
Put 9 as the next digit of the answer. 
Result so far: 56032.4971209
If we subtract 4689 from 4800, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 16:
521 goes into 1110 2 times with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 56032.49712092
Subtract 1042 from 1110 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 56032.49712092 with a balance of 6.8e-08.
