Let's divide 75809768 by 591
The aim is to understand the frequency of 591 in 75809768.

Moving on to step 1:
7 divided by 591 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 591

Step 2:
The number 591 fits into 75 0 times, leaving a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Bring next digit (8) of the dividend behind the 75 and repeat the process: 758 / 591

Going ahead to step 3:
When dividing 758 by 591, we get 1 with a remainder of 167.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 591 from 758 leaves us with 167.
Take the next digit (0) from the dividend and append it to 167, then repeat: 1670 / 591

Let's proceed to step 4:
1670 divided by 591 is 2 with a remainder of 488.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 488 after subtracting 1182 from 1670.
Fetch the next digit (9) from the dividend, attach it to 488 and continue: 4889 / 591

Advancing to step 5:
If we divide 4889 by 591, we get 8 and a remainder of 161.
The next digit of our result is 8. 
Result so far: 128.0
The remainder is 161 after subtracting 4728 from 4889.
Take the next digit (7) from the dividend and append it to 161, then repeat: 1617 / 591

Moving on to step 6:
If we divide 1617 by 591, we get 2 and a remainder of 435.
Write down 2 as next digit of the result. 
Result so far: 1282.0
The remainder is 435 after subtracting 1182 from 1617.
Grab the next digit (6) from the dividend, add it to 435, then carry on: 4356 / 591

Step 7:
The number 591 fits into 4356 7 times, leaving a remainder of 219.
The number 7 becomes the next digit in our result. 
Result so far: 12827.0
The remainder is 219 after subtracting 4137 from 4356.
Fetch the next digit (8) from the dividend, attach it to 219 and continue: 2198 / 591

On to step 8:
When dividing 2198 by 591, we get 3 with a remainder of 425.
Write down 3 as next digit of the result. 
Result so far: 128273.0
Subtracting 1773 from 2198 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 9:
591 can be fit into 4250 7 times, resulting in a remainder of 113.
Use 7 as the next digit of our solution. 
Result so far: 128273.7
Subtracting 4137 from 4250 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 10:
If we divide 1130 by 591, we get 1 and a remainder of 539.
The number 1 becomes the next digit in our result. 
Result so far: 128273.71
If we subtract 591 from 1130, we get 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Moving on to step 11:
When dividing 5390 by 591, we get 9 with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 128273.719
If we subtract 5319 from 5390, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 12:
710 divided by 591 is 1 with a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 128273.7191
Subtracting 591 from 710 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 13:
591 can be fit into 1190 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 128273.71912
Subtract 1182 from 1190 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
If we divide 80 by 591, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 128273.71912
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 15:
When dividing 800 by 591, we get 1 with a remainder of 209.
Record the quotient 1 as the next digit in the result. 
Result so far: 128273.7191201
Deduct 591 from 800 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 16:
591 goes into 2090 3 times with a remainder of 317.
Record the quotient 3 as the next digit in the result. 
Result so far: 128273.71912013
If we subtract 1773 from 2090, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

The quotient of the division is 128273.71912013, and the remainder is 3.17e-07.
