Let's divide 96729768 by 591
The aim is to understand the frequency of 591 in 96729768.

On to step 1:
591 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 591

Step 2:
If we divide 96 by 591, we get 0 and a remainder of 96.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 96, we end up with 96.
Take the next digit (7) from the dividend and append it to 96, then repeat: 967 / 591

Moving on to step 3:
591 can be fit into 967 1 times, resulting in a remainder of 376.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 376 after subtracting 591 from 967.
Include the next digit (2) from the dividend after 376, then repeat: 3762 / 591

Moving on to step 4:
591 can be fit into 3762 6 times, resulting in a remainder of 216.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 3546 from 3762 and we're left with 216.
Grab the next digit (9) from the dividend, add it to 216, then carry on: 2169 / 591

Going ahead to step 5:
591 can be fit into 2169 3 times, resulting in a remainder of 396.
The next digit of our result is 3. 
Result so far: 163.0
The remainder is 396 after subtracting 1773 from 2169.
Take the next digit (7) from the dividend and append it to 396, then repeat: 3967 / 591

Moving on to step 6:
591 can be fit into 3967 6 times, resulting in a remainder of 421.
Write down 6 as next digit of the result. 
Result so far: 1636.0
The remainder is 421 after subtracting 3546 from 3967.
Bring next digit (6) of the dividend behind the 421 and repeat the process: 4216 / 591

Let's proceed to step 7:
If we divide 4216 by 591, we get 7 and a remainder of 79.
Put 7 as the next digit of the answer. 
Result so far: 16367.0
Deduct 4137 from 4216 and we're left with 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 591

Going ahead to step 8:
591 can be fit into 798 1 times, resulting in a remainder of 207.
The next digit of our result is 1. 
Result so far: 163671.0
Subtract 591 from 798 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 9:
2070 divided by 591 is 3 with a remainder of 297.
Write down 3 as next digit of the result. 
Result so far: 163671.3
Subtracting 1773 from 2070 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Advancing to step 10:
When dividing 2970 by 591, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 163671.35
Deduct 2955 from 2970 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
The number 591 fits into 150 0 times, leaving a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 163671.35
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
If we divide 1500 by 591, we get 2 and a remainder of 318.
Record the quotient 2 as the next digit in the result. 
Result so far: 163671.3502
Subtracting 1182 from 1500 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 13:
If we divide 3180 by 591, we get 5 and a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 163671.35025
Subtract 2955 from 3180 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 14:
591 can be fit into 2250 3 times, resulting in a remainder of 477.
Put 3 as the next digit of the answer. 
Result so far: 163671.350253
The remainder is 477 after subtracting 1773 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Step 15:
4770 divided by 591 is 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 163671.3502538
The remainder is 42 after subtracting 4728 from 4770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 16:
591 can be fit into 420 0 times, resulting in a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 163671.3502538
The remainder is 420 after subtracting 0 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The final result is 163671.3502538 with a remainder of 4.2e-07.
