17871827 ÷ 687 
The aim is to understand the frequency of 687 in 17871827.

Advancing to step 1:
687 can be fit into 1 0 times, resulting in 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.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 687

Let's proceed to step 2:
When dividing 17 by 687, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 687

Step 3:
If we divide 178 by 687, we get 0 and a remainder of 178.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 178 and we're left with 178.
Take the next digit (7) from the dividend and append it to 178, then repeat: 1787 / 687

Let's proceed to step 4:
The number 687 fits into 1787 2 times, leaving a remainder of 413.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1374 from 1787, we get 413.
Take the next digit (1) from the dividend and append it to 413, then repeat: 4131 / 687

Step 5:
The number 687 fits into 4131 6 times, leaving a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 4122 from 4131 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 687

Going ahead to step 6:
687 can be fit into 98 0 times, resulting in a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 260.0
The remainder is 98 after subtracting 0 from 98.
Append the next digit (2) from the dividend to 98 and continue with: 982 / 687

Moving on to step 7:
982 divided by 687 is 1 with a remainder of 295.
The next digit of our result is 1. 
Result so far: 2601.0
The remainder is 295 after subtracting 687 from 982.
Take the next digit (7) from the dividend and append it to 295, then repeat: 2957 / 687

Let's proceed to step 8:
687 can be fit into 2957 4 times, resulting in a remainder of 209.
The next digit of our result is 4. 
Result so far: 26014.0
Subtract 2748 from 2957 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 9:
If we divide 2090 by 687, we get 3 and a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 26014.3
Subtracting 2061 from 2090 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 10:
The number 687 fits into 290 0 times, leaving a remainder of 290.
The next digit of our result is 0. 
Result so far: 26014.3
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 11:
687 can be fit into 2900 4 times, resulting in a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 26014.304
If we subtract 2748 from 2900, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 12:
687 can be fit into 1520 2 times, resulting in a remainder of 146.
Use 2 as the next digit of our solution. 
Result so far: 26014.3042
If we take 1374 away from 1520, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 13:
If we divide 1460 by 687, we get 2 and a remainder of 86.
Write down 2 as next digit of the result. 
Result so far: 26014.30422
The remainder is 86 after subtracting 1374 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Our division results in 26014.30422 with a remaining 8.6e-05.
