We're dividing 5773851 by 591 
The aim is to understand the frequency of 591 in 5773851.

Step 1:
The number 591 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 591

Let's proceed to step 2:
591 can be fit into 57 0 times, resulting in a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Append the next digit (7) from the dividend to 57 and continue with: 577 / 591

Let's proceed to step 3:
591 goes into 577 0 times with a remainder of 577.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 577, we end up with 577.
Grab the next digit (3) from the dividend, add it to 577, then carry on: 5773 / 591

Let's proceed to step 4:
591 can be fit into 5773 9 times, resulting in a remainder of 454.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 5319 away from 5773, we end up with 454.
Include the next digit (8) from the dividend after 454, then repeat: 4548 / 591

On to step 5:
When dividing 4548 by 591, we get 7 with a remainder of 411.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Deduct 4137 from 4548 and we're left with 411.
Include the next digit (5) from the dividend after 411, then repeat: 4115 / 591

Step 6:
591 can be fit into 4115 6 times, resulting in a remainder of 569.
Use 6 as the next digit of our solution. 
Result so far: 976.0
If we subtract 3546 from 4115, we get 569.
Grab the next digit (1) from the dividend, add it to 569, then carry on: 5691 / 591

Step 7:
591 goes into 5691 9 times with a remainder of 372.
Put 9 as the next digit of the answer. 
Result so far: 9769.0
Subtract 5319 from 5691 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 8:
3720 divided by 591 is 6 with a remainder of 174.
The number 6 becomes the next digit in our result. 
Result so far: 9769.6
Subtract 3546 from 3720 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 9:
The number 591 fits into 1740 2 times, leaving a remainder of 558.
Record the quotient 2 as the next digit in the result. 
Result so far: 9769.62
Subtract 1182 from 1740 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Let's proceed to step 10:
If we divide 5580 by 591, we get 9 and a remainder of 261.
Record the quotient 9 as the next digit in the result. 
Result so far: 9769.629
If we take 5319 away from 5580, we end up with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 11:
The number 591 fits into 2610 4 times, leaving a remainder of 246.
Use 4 as the next digit of our solution. 
Result so far: 9769.6294
If we subtract 2364 from 2610, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 12:
2460 divided by 591 is 4 with a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 9769.62944
Subtracting 2364 from 2460 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Our division results in 9769.62944 with a remaining 9.6e-05.
