65040155 divided by 591 
The aim is to understand the frequency of 591 in 65040155.

Moving on to step 1:
591 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 591

Step 2:
591 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Grab the next digit (0) from the dividend, add it to 65, then carry on: 650 / 591

Going ahead to step 3:
If we divide 650 by 591, we get 1 and a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 591 from 650 to get 59.
Take the next digit (4) from the dividend and append it to 59, then repeat: 594 / 591

Step 4:
When dividing 594 by 591, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 591 from 594 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 591

Going ahead to step 5:
The number 591 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 591

Let's proceed to step 6:
When dividing 301 by 591, we get 0 with a remainder of 301.
Put 0 as the next digit of the answer. 
Result so far: 1100.0
Deduct 0 from 301 and we're left with 301.
Fetch the next digit (5) from the dividend, attach it to 301 and continue: 3015 / 591

Advancing to step 7:
3015 divided by 591 is 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 11005.0
If we take 2955 away from 3015, we end up with 60.
Take the next digit (5) from the dividend and append it to 60, then repeat: 605 / 591

Advancing to step 8:
If we divide 605 by 591, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 110051.0
Subtract 591 from 605 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
The number 591 fits into 140 0 times, leaving a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 110051.0
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
The number 591 fits into 1400 2 times, leaving a remainder of 218.
The next digit of our result is 2. 
Result so far: 110051.02
Deduct 1182 from 1400 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 11:
591 goes into 2180 3 times with a remainder of 407.
The number 3 becomes the next digit in our result. 
Result so far: 110051.023
Deduct 1773 from 2180 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 12:
591 goes into 4070 6 times with a remainder of 524.
The next digit of our result is 6. 
Result so far: 110051.0236
Deduct 3546 from 4070 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 13:
If we divide 5240 by 591, we get 8 and a remainder of 512.
Write down 8 as next digit of the result. 
Result so far: 110051.02368
If we take 4728 away from 5240, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 14:
591 goes into 5120 8 times with a remainder of 392.
The number 8 becomes the next digit in our result. 
Result so far: 110051.023688
Deduct 4728 from 5120 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final outcome is 110051.023688, with a leftover of 3.92e-05.
