We're dividing 86008405 by 687 
The aim is to understand the frequency of 687 in 86008405.

Let's proceed to step 1:
The number 687 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 687

Moving on to step 2:
86 divided by 687 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Grab the next digit (0) from the dividend, add it to 86, then carry on: 860 / 687

Advancing to step 3:
When dividing 860 by 687, we get 1 with a remainder of 173.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 687 from 860 to get 173.
Include the next digit (0) from the dividend after 173, then repeat: 1730 / 687

Step 4:
687 goes into 1730 2 times with a remainder of 356.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1374 from 1730, we get 356.
Bring next digit (8) of the dividend behind the 356 and repeat the process: 3568 / 687

Going ahead to step 5:
When dividing 3568 by 687, we get 5 with a remainder of 133.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtracting 3435 from 3568 leaves us with 133.
Take the next digit (4) from the dividend and append it to 133, then repeat: 1334 / 687

Moving on to step 6:
687 goes into 1334 1 times with a remainder of 647.
Put 1 as the next digit of the answer. 
Result so far: 1251.0
If we take 687 away from 1334, we end up with 647.
Append the next digit (0) from the dividend to 647 and continue with: 6470 / 687

Step 7:
687 goes into 6470 9 times with a remainder of 287.
Put 9 as the next digit of the answer. 
Result so far: 12519.0
Subtract 6183 from 6470 to get 287.
Fetch the next digit (5) from the dividend, attach it to 287 and continue: 2875 / 687

On to step 8:
687 can be fit into 2875 4 times, resulting in a remainder of 127.
The next digit of our result is 4. 
Result so far: 125194.0
Subtracting 2748 from 2875 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 9:
If we divide 1270 by 687, we get 1 and a remainder of 583.
Use 1 as the next digit of our solution. 
Result so far: 125194.1
Subtract 687 from 1270 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Let's proceed to step 10:
687 can be fit into 5830 8 times, resulting in a remainder of 334.
The number 8 becomes the next digit in our result. 
Result so far: 125194.18
If we subtract 5496 from 5830, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 11:
The number 687 fits into 3340 4 times, leaving a remainder of 592.
Put 4 as the next digit of the answer. 
Result so far: 125194.184
The remainder is 592 after subtracting 2748 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 12:
687 can be fit into 5920 8 times, resulting in a remainder of 424.
Record the quotient 8 as the next digit in the result. 
Result so far: 125194.1848
Deduct 5496 from 5920 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 13:
The number 687 fits into 4240 6 times, leaving a remainder of 118.
Record the quotient 6 as the next digit in the result. 
Result so far: 125194.18486
Deduct 4122 from 4240 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 14:
When dividing 1180 by 687, we get 1 with a remainder of 493.
Record the quotient 1 as the next digit in the result. 
Result so far: 125194.184861
Subtract 687 from 1180 to get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Advancing to step 15:
When dividing 4930 by 687, we get 7 with a remainder of 121.
Use 7 as the next digit of our solution. 
Result so far: 125194.1848617
Subtracting 4809 from 4930 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 16:
The number 687 fits into 1210 1 times, leaving a remainder of 523.
Put 1 as the next digit of the answer. 
Result so far: 125194.18486171
Subtract 687 from 1210 to get 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

The quotient of the division is 125194.18486171, and the remainder is 5.23e-07.
