We look at the division of 11744628 by 591 
The aim is to understand the frequency of 591 in 11744628.

Moving on to step 1:
591 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 591

Moving on to step 2:
591 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 591

Going ahead to step 3:
591 goes into 117 0 times with a remainder of 117.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 117, we get 117.
Take the next digit (4) from the dividend and append it to 117, then repeat: 1174 / 591

On to step 4:
591 goes into 1174 1 times with a remainder of 583.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 591 from 1174 leaves us with 583.
Append the next digit (4) from the dividend to 583 and continue with: 5834 / 591

Let's proceed to step 5:
The number 591 fits into 5834 9 times, leaving a remainder of 515.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 5319 from 5834 and we're left with 515.
Fetch the next digit (6) from the dividend, attach it to 515 and continue: 5156 / 591

Going ahead to step 6:
If we divide 5156 by 591, we get 8 and a remainder of 428.
The next digit of our result is 8. 
Result so far: 198.0
Subtract 4728 from 5156 to get 428.
Fetch the next digit (2) from the dividend, attach it to 428 and continue: 4282 / 591

Moving on to step 7:
591 goes into 4282 7 times with a remainder of 145.
Use 7 as the next digit of our solution. 
Result so far: 1987.0
If we take 4137 away from 4282, we end up with 145.
Append the next digit (8) from the dividend to 145 and continue with: 1458 / 591

Advancing to step 8:
1458 divided by 591 is 2 with a remainder of 276.
Record the quotient 2 as the next digit in the result. 
Result so far: 19872.0
If we take 1182 away from 1458, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 9:
2760 divided by 591 is 4 with a remainder of 396.
The number 4 becomes the next digit in our result. 
Result so far: 19872.4
If we subtract 2364 from 2760, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 10:
591 can be fit into 3960 6 times, resulting in a remainder of 414.
The next digit of our result is 6. 
Result so far: 19872.46
The remainder is 414 after subtracting 3546 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 11:
4140 divided by 591 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 19872.467
Subtracting 4137 from 4140 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
591 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 19872.467
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
300 divided by 591 is 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 19872.467
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 19872.467, with a leftover of 0.0003.
