15262712 ÷ 866 
The aim is to understand the frequency of 866 in 15262712.

Moving on to step 1:
866 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
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 / 866

Moving on to step 2:
When dividing 15 by 866, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 866

On to step 3:
If we divide 152 by 866, we get 0 and a remainder of 152.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 152, we get 152.
Take the next digit (6) from the dividend and append it to 152, then repeat: 1526 / 866

On to step 4:
The number 866 fits into 1526 1 times, leaving a remainder of 660.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 866 from 1526 leaves us with 660.
Include the next digit (2) from the dividend after 660, then repeat: 6602 / 866

Let's proceed to step 5:
When dividing 6602 by 866, we get 7 with a remainder of 540.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 6062 from 6602, we get 540.
Fetch the next digit (7) from the dividend, attach it to 540 and continue: 5407 / 866

Advancing to step 6:
866 can be fit into 5407 6 times, resulting in a remainder of 211.
The next digit of our result is 6. 
Result so far: 176.0
The remainder is 211 after subtracting 5196 from 5407.
Bring next digit (1) of the dividend behind the 211 and repeat the process: 2111 / 866

Step 7:
When dividing 2111 by 866, we get 2 with a remainder of 379.
Record the quotient 2 as the next digit in the result. 
Result so far: 1762.0
If we take 1732 away from 2111, we end up with 379.
Fetch the next digit (2) from the dividend, attach it to 379 and continue: 3792 / 866

Going ahead to step 8:
If we divide 3792 by 866, we get 4 and a remainder of 328.
Use 4 as the next digit of our solution. 
Result so far: 17624.0
Deduct 3464 from 3792 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 9:
When dividing 3280 by 866, we get 3 with a remainder of 682.
Put 3 as the next digit of the answer. 
Result so far: 17624.3
Subtracting 2598 from 3280 leaves us with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Let's proceed to step 10:
The number 866 fits into 6820 7 times, leaving a remainder of 758.
Put 7 as the next digit of the answer. 
Result so far: 17624.37
Subtracting 6062 from 6820 leaves us with 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

On to step 11:
866 can be fit into 7580 8 times, resulting in a remainder of 652.
Record the quotient 8 as the next digit in the result. 
Result so far: 17624.378
Subtracting 6928 from 7580 leaves us with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

On to step 12:
If we divide 6520 by 866, we get 7 and a remainder of 458.
Put 7 as the next digit of the answer. 
Result so far: 17624.3787
Subtract 6062 from 6520 to get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Moving on to step 13:
4580 divided by 866 is 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 17624.37875
If we take 4330 away from 4580, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 14:
866 goes into 2500 2 times with a remainder of 768.
The next digit of our result is 2. 
Result so far: 17624.378752
Subtract 1732 from 2500 to get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Advancing to step 15:
The number 866 fits into 7680 8 times, leaving a remainder of 752.
Record the quotient 8 as the next digit in the result. 
Result so far: 17624.3787528
Subtracting 6928 from 7680 leaves us with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Moving on to step 16:
7520 divided by 866 is 8 with a remainder of 592.
The next digit of our result is 8. 
Result so far: 17624.37875288
Deduct 6928 from 7520 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Our division results in 17624.37875288 with a remaining 5.92e-07.
