We're dividing 53580649 by 913 
The aim is to understand the frequency of 913 in 53580649.

Going ahead to step 1:
The number 913 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 913

Advancing to step 2:
When dividing 53 by 913, we get 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 913

Moving on to step 3:
If we divide 535 by 913, we get 0 and a remainder of 535.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 535, we get 535.
Include the next digit (8) from the dividend after 535, then repeat: 5358 / 913

On to step 4:
When dividing 5358 by 913, we get 5 with a remainder of 793.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4565 from 5358 to get 793.
Append the next digit (0) from the dividend to 793 and continue with: 7930 / 913

Let's proceed to step 5:
7930 divided by 913 is 8 with a remainder of 626.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
If we subtract 7304 from 7930, we get 626.
Append the next digit (6) from the dividend to 626 and continue with: 6266 / 913

Moving on to step 6:
913 goes into 6266 6 times with a remainder of 788.
Write down 6 as next digit of the result. 
Result so far: 586.0
Subtract 5478 from 6266 to get 788.
Bring next digit (4) of the dividend behind the 788 and repeat the process: 7884 / 913

On to step 7:
913 goes into 7884 8 times with a remainder of 580.
Put 8 as the next digit of the answer. 
Result so far: 5868.0
If we subtract 7304 from 7884, we get 580.
Fetch the next digit (9) from the dividend, attach it to 580 and continue: 5809 / 913

Step 8:
The number 913 fits into 5809 6 times, leaving a remainder of 331.
Record the quotient 6 as the next digit in the result. 
Result so far: 58686.0
The remainder is 331 after subtracting 5478 from 5809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 9:
913 can be fit into 3310 3 times, resulting in a remainder of 571.
Record the quotient 3 as the next digit in the result. 
Result so far: 58686.3
If we take 2739 away from 3310, we end up with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Step 10:
5710 divided by 913 is 6 with a remainder of 232.
Put 6 as the next digit of the answer. 
Result so far: 58686.36
Subtract 5478 from 5710 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 11:
If we divide 2320 by 913, we get 2 and a remainder of 494.
Put 2 as the next digit of the answer. 
Result so far: 58686.362
The remainder is 494 after subtracting 1826 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Step 12:
When dividing 4940 by 913, we get 5 with a remainder of 375.
The next digit of our result is 5. 
Result so far: 58686.3625
Subtract 4565 from 4940 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 13:
When dividing 3750 by 913, we get 4 with a remainder of 98.
The number 4 becomes the next digit in our result. 
Result so far: 58686.36254
Deduct 3652 from 3750 and we're left 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.

Moving on to step 14:
If we divide 980 by 913, we get 1 and a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 58686.362541
Deduct 913 from 980 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 15:
If we divide 670 by 913, we get 0 and a remainder of 670.
Record the quotient 0 as the next digit in the result. 
Result so far: 58686.362541
Subtracting 0 from 670 leaves us with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 16:
913 goes into 6700 7 times with a remainder of 309.
Put 7 as the next digit of the answer. 
Result so far: 58686.36254107
The remainder is 309 after subtracting 6391 from 6700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

In conclusion, the division gives 58686.36254107 with a balance of 3.09e-07.
