We're dividing 76934342 by 591 
The aim is to understand the frequency of 591 in 76934342.

On to step 1:
The number 591 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 591

On to step 2:
If we divide 76 by 591, we get 0 and a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Bring next digit (9) of the dividend behind the 76 and repeat the process: 769 / 591

On to step 3:
When dividing 769 by 591, we get 1 with a remainder of 178.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 178 after subtracting 591 from 769.
Append the next digit (3) from the dividend to 178 and continue with: 1783 / 591

Moving on to step 4:
591 can be fit into 1783 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1773 from 1783 to get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 591

Step 5:
591 can be fit into 104 0 times, resulting in a remainder of 104.
Use 0 as the next digit of our solution. 
Result so far: 130.0
If we take 0 away from 104, we end up with 104.
Grab the next digit (3) from the dividend, add it to 104, then carry on: 1043 / 591

Advancing to step 6:
If we divide 1043 by 591, we get 1 and a remainder of 452.
The number 1 becomes the next digit in our result. 
Result so far: 1301.0
If we subtract 591 from 1043, we get 452.
Grab the next digit (4) from the dividend, add it to 452, then carry on: 4524 / 591

Going ahead to step 7:
When dividing 4524 by 591, we get 7 with a remainder of 387.
The next digit of our result is 7. 
Result so far: 13017.0
If we subtract 4137 from 4524, we get 387.
Take the next digit (2) from the dividend and append it to 387, then repeat: 3872 / 591

Let's proceed to step 8:
The number 591 fits into 3872 6 times, leaving a remainder of 326.
Write down 6 as next digit of the result. 
Result so far: 130176.0
The remainder is 326 after subtracting 3546 from 3872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 9:
The number 591 fits into 3260 5 times, leaving a remainder of 305.
Put 5 as the next digit of the answer. 
Result so far: 130176.5
Subtracting 2955 from 3260 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 10:
3050 divided by 591 is 5 with a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 130176.55
Subtracting 2955 from 3050 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

After the division, we end up with 130176.55 and a remainder of 0.095.
