We're dividing 40185030 by 687 
The aim is to understand the frequency of 687 in 40185030.

Let's proceed to step 1:
687 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 687

Let's proceed to step 2:
687 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 687

Moving on to step 3:
401 divided by 687 is 0 with a remainder of 401.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 401 and we're left with 401.
Append the next digit (8) from the dividend to 401 and continue with: 4018 / 687

Step 4:
The number 687 fits into 4018 5 times, leaving a remainder of 583.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 3435 from 4018 leaves us with 583.
Take the next digit (5) from the dividend and append it to 583, then repeat: 5835 / 687

On to step 5:
5835 divided by 687 is 8 with a remainder of 339.
Use 8 as the next digit of our solution. 
Result so far: 58.0
If we subtract 5496 from 5835, we get 339.
Grab the next digit (0) from the dividend, add it to 339, then carry on: 3390 / 687

Let's proceed to step 6:
687 can be fit into 3390 4 times, resulting in a remainder of 642.
Use 4 as the next digit of our solution. 
Result so far: 584.0
If we take 2748 away from 3390, we end up with 642.
Grab the next digit (3) from the dividend, add it to 642, then carry on: 6423 / 687

Going ahead to step 7:
6423 divided by 687 is 9 with a remainder of 240.
Use 9 as the next digit of our solution. 
Result so far: 5849.0
The remainder is 240 after subtracting 6183 from 6423.
Grab the next digit (0) from the dividend, add it to 240, then carry on: 2400 / 687

Moving on to step 8:
The number 687 fits into 2400 3 times, leaving a remainder of 339.
Write down 3 as next digit of the result. 
Result so far: 58493.0
If we subtract 2061 from 2400, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Let's proceed to step 9:
When dividing 3390 by 687, we get 4 with a remainder of 642.
Put 4 as the next digit of the answer. 
Result so far: 58493.4
The remainder is 642 after subtracting 2748 from 3390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Let's proceed to step 10:
When dividing 6420 by 687, we get 9 with a remainder of 237.
Use 9 as the next digit of our solution. 
Result so far: 58493.49
The remainder is 237 after subtracting 6183 from 6420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 11:
2370 divided by 687 is 3 with a remainder of 309.
Use 3 as the next digit of our solution. 
Result so far: 58493.493
Subtracting 2061 from 2370 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Advancing to step 12:
687 goes into 3090 4 times with a remainder of 342.
Record the quotient 4 as the next digit in the result. 
Result so far: 58493.4934
Subtract 2748 from 3090 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 13:
When dividing 3420 by 687, we get 4 with a remainder of 672.
The next digit of our result is 4. 
Result so far: 58493.49344
Subtract 2748 from 3420 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The quotient of the division is 58493.49344, and the remainder is 0.000672.
