15726087 ÷ 513 
The aim is to understand the frequency of 513 in 15726087.

Step 1:
513 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 513

Step 2:
513 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 513

Advancing to step 3:
157 divided by 513 is 0 with a remainder of 157.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 157 to get 157.
Fetch the next digit (2) from the dividend, attach it to 157 and continue: 1572 / 513

Step 4:
1572 divided by 513 is 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 1539 from 1572, we get 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 513

On to step 5:
513 goes into 336 0 times with a remainder of 336.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 336 leaves us with 336.
Bring next digit (0) of the dividend behind the 336 and repeat the process: 3360 / 513

On to step 6:
The number 513 fits into 3360 6 times, leaving a remainder of 282.
Use 6 as the next digit of our solution. 
Result so far: 306.0
If we take 3078 away from 3360, we end up with 282.
Bring next digit (8) of the dividend behind the 282 and repeat the process: 2828 / 513

Advancing to step 7:
If we divide 2828 by 513, we get 5 and a remainder of 263.
The next digit of our result is 5. 
Result so far: 3065.0
Subtract 2565 from 2828 to get 263.
Include the next digit (7) from the dividend after 263, then repeat: 2637 / 513

Advancing to step 8:
2637 divided by 513 is 5 with a remainder of 72.
The next digit of our result is 5. 
Result so far: 30655.0
If we take 2565 away from 2637, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
When dividing 720 by 513, we get 1 with a remainder of 207.
The number 1 becomes the next digit in our result. 
Result so far: 30655.1
Subtract 513 from 720 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.

Advancing to step 10:
When dividing 2070 by 513, we get 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 30655.14
Subtracting 2052 from 2070 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
When dividing 180 by 513, we get 0 with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 30655.14
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 12:
The number 513 fits into 1800 3 times, leaving a remainder of 261.
The number 3 becomes the next digit in our result. 
Result so far: 30655.1403
Subtract 1539 from 1800 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Moving on to step 13:
513 can be fit into 2610 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 30655.14035
Subtracting 2565 from 2610 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 14:
450 divided by 513 is 0 with a remainder of 450.
The next digit of our result is 0. 
Result so far: 30655.14035
If we take 0 away from 450, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 15:
4500 divided by 513 is 8 with a remainder of 396.
The number 8 becomes the next digit in our result. 
Result so far: 30655.1403508
If we subtract 4104 from 4500, 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.

Let's proceed to step 16:
3960 divided by 513 is 7 with a remainder of 369.
Write down 7 as next digit of the result. 
Result so far: 30655.14035087
Subtracting 3591 from 3960 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

In conclusion, the division gives 30655.14035087 with a balance of 3.69e-07.
