We look at the division of 77597234 by 591 
The aim is to understand the frequency of 591 in 77597234.

On to step 1:
7 divided by 591 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 591

Advancing to step 2:
591 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Bring next digit (5) of the dividend behind the 77 and repeat the process: 775 / 591

Going ahead to step 3:
If we divide 775 by 591, we get 1 and a remainder of 184.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 184 after subtracting 591 from 775.
Take the next digit (9) from the dividend and append it to 184, then repeat: 1849 / 591

Let's proceed to step 4:
591 goes into 1849 3 times with a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1773 from 1849 to get 76.
Take the next digit (7) from the dividend and append it to 76, then repeat: 767 / 591

Moving on to step 5:
When dividing 767 by 591, we get 1 with a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Subtracting 591 from 767 leaves us with 176.
Take the next digit (2) from the dividend and append it to 176, then repeat: 1762 / 591

Going ahead to step 6:
If we divide 1762 by 591, we get 2 and a remainder of 580.
The number 2 becomes the next digit in our result. 
Result so far: 1312.0
Deduct 1182 from 1762 and we're left with 580.
Take the next digit (3) from the dividend and append it to 580, then repeat: 5803 / 591

On to step 7:
When dividing 5803 by 591, we get 9 with a remainder of 484.
Write down 9 as next digit of the result. 
Result so far: 13129.0
If we subtract 5319 from 5803, we get 484.
Append the next digit (4) from the dividend to 484 and continue with: 4844 / 591

Step 8:
591 goes into 4844 8 times with a remainder of 116.
The number 8 becomes the next digit in our result. 
Result so far: 131298.0
Subtracting 4728 from 4844 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 9:
591 can be fit into 1160 1 times, resulting in a remainder of 569.
The number 1 becomes the next digit in our result. 
Result so far: 131298.1
The remainder is 569 after subtracting 591 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Moving on to step 10:
591 goes into 5690 9 times with a remainder of 371.
The next digit of our result is 9. 
Result so far: 131298.19
If we subtract 5319 from 5690, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

On to step 11:
If we divide 3710 by 591, we get 6 and a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 131298.196
Deduct 3546 from 3710 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 12:
591 can be fit into 1640 2 times, resulting in a remainder of 458.
Put 2 as the next digit of the answer. 
Result so far: 131298.1962
Deduct 1182 from 1640 and we're left with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 13:
The number 591 fits into 4580 7 times, leaving a remainder of 443.
Record the quotient 7 as the next digit in the result. 
Result so far: 131298.19627
Subtracting 4137 from 4580 leaves us with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Let's proceed to step 14:
If we divide 4430 by 591, we get 7 and a remainder of 293.
Use 7 as the next digit of our solution. 
Result so far: 131298.196277
The remainder is 293 after subtracting 4137 from 4430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

The quotient of the division is 131298.196277, and the remainder is 2.93e-05.
