We look at the division of 987014 by 687 
The aim is to understand the frequency of 687 in 987014.

Going ahead to step 1:
The number 687 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 687

Moving on to step 2:
When dividing 98 by 687, we get 0 with a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Bring next digit (7) of the dividend behind the 98 and repeat the process: 987 / 687

Let's proceed to step 3:
When dividing 987 by 687, we get 1 with a remainder of 300.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 687 from 987 to get 300.
Take the next digit (0) from the dividend and append it to 300, then repeat: 3000 / 687

Step 4:
3000 divided by 687 is 4 with a remainder of 252.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 2748 from 3000 and we're left with 252.
Fetch the next digit (1) from the dividend, attach it to 252 and continue: 2521 / 687

Moving on to step 5:
687 can be fit into 2521 3 times, resulting in a remainder of 460.
Put 3 as the next digit of the answer. 
Result so far: 143.0
The remainder is 460 after subtracting 2061 from 2521.
Grab the next digit (4) from the dividend, add it to 460, then carry on: 4604 / 687

Step 6:
The number 687 fits into 4604 6 times, leaving a remainder of 482.
The next digit of our result is 6. 
Result so far: 1436.0
If we subtract 4122 from 4604, we get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Moving on to step 7:
687 goes into 4820 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 1436.7
The remainder is 11 after subtracting 4809 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
When dividing 110 by 687, we get 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 1436.7
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 9:
When dividing 1100 by 687, we get 1 with a remainder of 413.
Use 1 as the next digit of our solution. 
Result so far: 1436.701
Deduct 687 from 1100 and we're left with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Moving on to step 10:
The number 687 fits into 4130 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1436.7016
Deduct 4122 from 4130 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
687 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 1436.7016
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
If we divide 800 by 687, we get 1 and a remainder of 113.
Write down 1 as next digit of the result. 
Result so far: 1436.701601
If we subtract 687 from 800, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 13:
687 can be fit into 1130 1 times, resulting in a remainder of 443.
Put 1 as the next digit of the answer. 
Result so far: 1436.7016011
Subtract 687 from 1130 to get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

The final outcome is 1436.7016011, with a leftover of 4.43e-06.
