We look at the division of 69548296 by 687 
The aim is to understand the frequency of 687 in 69548296.

Step 1:
When dividing 6 by 687, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 687

Going ahead to step 2:
If we divide 69 by 687, we get 0 and a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Take the next digit (5) from the dividend and append it to 69, then repeat: 695 / 687

Going ahead to step 3:
The number 687 fits into 695 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 8 after subtracting 687 from 695.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 687

Step 4:
If we divide 84 by 687, we get 0 and a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 84, we end up with 84.
Include the next digit (8) from the dividend after 84, then repeat: 848 / 687

On to step 5:
848 divided by 687 is 1 with a remainder of 161.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
If we take 687 away from 848, we end up with 161.
Grab the next digit (2) from the dividend, add it to 161, then carry on: 1612 / 687

Moving on to step 6:
The number 687 fits into 1612 2 times, leaving a remainder of 238.
Put 2 as the next digit of the answer. 
Result so far: 1012.0
Subtracting 1374 from 1612 leaves us with 238.
Take the next digit (9) from the dividend and append it to 238, then repeat: 2389 / 687

Let's proceed to step 7:
687 can be fit into 2389 3 times, resulting in a remainder of 328.
Write down 3 as next digit of the result. 
Result so far: 10123.0
The remainder is 328 after subtracting 2061 from 2389.
Grab the next digit (6) from the dividend, add it to 328, then carry on: 3286 / 687

Step 8:
687 can be fit into 3286 4 times, resulting in a remainder of 538.
Write down 4 as next digit of the result. 
Result so far: 101234.0
Subtracting 2748 from 3286 leaves us with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Moving on to step 9:
The number 687 fits into 5380 7 times, leaving a remainder of 571.
Put 7 as the next digit of the answer. 
Result so far: 101234.7
Subtracting 4809 from 5380 leaves us with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Step 10:
The number 687 fits into 5710 8 times, leaving a remainder of 214.
The number 8 becomes the next digit in our result. 
Result so far: 101234.78
Deduct 5496 from 5710 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 11:
When dividing 2140 by 687, we get 3 with a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 101234.783
Deduct 2061 from 2140 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 12:
687 goes into 790 1 times with a remainder of 103.
The next digit of our result is 1. 
Result so far: 101234.7831
Subtract 687 from 790 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 13:
The number 687 fits into 1030 1 times, leaving a remainder of 343.
Put 1 as the next digit of the answer. 
Result so far: 101234.78311
Deduct 687 from 1030 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

The final result is 101234.78311 with a remainder of 0.000343.
