Let's divide 15191290 by 591
The aim is to understand the frequency of 591 in 15191290.

Going ahead to step 1:
If we divide 1 by 591, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 591

Moving on to step 2:
When dividing 15 by 591, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 591

On to step 3:
151 divided by 591 is 0 with a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 151 after subtracting 0 from 151.
Fetch the next digit (9) from the dividend, attach it to 151 and continue: 1519 / 591

Advancing to step 4:
1519 divided by 591 is 2 with a remainder of 337.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1182 from 1519 leaves us with 337.
Include the next digit (1) from the dividend after 337, then repeat: 3371 / 591

Let's proceed to step 5:
When dividing 3371 by 591, we get 5 with a remainder of 416.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 2955 away from 3371, we end up with 416.
Bring next digit (2) of the dividend behind the 416 and repeat the process: 4162 / 591

On to step 6:
4162 divided by 591 is 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 257.0
Deduct 4137 from 4162 and we're left with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 591

Let's proceed to step 7:
591 can be fit into 259 0 times, resulting in a remainder of 259.
Record the quotient 0 as the next digit in the result. 
Result so far: 2570.0
If we take 0 away from 259, we end up with 259.
Grab the next digit (0) from the dividend, add it to 259, then carry on: 2590 / 591

Let's proceed to step 8:
591 goes into 2590 4 times with a remainder of 226.
Put 4 as the next digit of the answer. 
Result so far: 25704.0
Subtract 2364 from 2590 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 9:
The number 591 fits into 2260 3 times, leaving a remainder of 487.
Write down 3 as next digit of the result. 
Result so far: 25704.3
Subtract 1773 from 2260 to get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

On to step 10:
591 can be fit into 4870 8 times, resulting in a remainder of 142.
Record the quotient 8 as the next digit in the result. 
Result so far: 25704.38
Subtracting 4728 from 4870 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 11:
The number 591 fits into 1420 2 times, leaving a remainder of 238.
Use 2 as the next digit of our solution. 
Result so far: 25704.382
Subtract 1182 from 1420 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 12:
591 can be fit into 2380 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 25704.3824
If we take 2364 away from 2380, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
160 divided by 591 is 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 25704.3824
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
591 goes into 1600 2 times with a remainder of 418.
Put 2 as the next digit of the answer. 
Result so far: 25704.382402
The remainder is 418 after subtracting 1182 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 15:
The number 591 fits into 4180 7 times, leaving a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 25704.3824027
If we take 4137 away from 4180, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 16:
If we divide 430 by 591, we get 0 and a remainder of 430.
Put 0 as the next digit of the answer. 
Result so far: 25704.3824027
The remainder is 430 after subtracting 0 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

In conclusion, the division gives 25704.3824027 with a balance of 4.3e-07.
