We're dividing 2208794 by 687 
The aim is to understand the frequency of 687 in 2208794.

On to step 1:
The number 687 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 687

Let's proceed to step 2:
If we divide 22 by 687, we get 0 and a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 687

Step 3:
687 goes into 220 0 times with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 220 and we're left with 220.
Fetch the next digit (8) from the dividend, attach it to 220 and continue: 2208 / 687

Moving on to step 4:
687 can be fit into 2208 3 times, resulting in a remainder of 147.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 2061 from 2208 leaves us with 147.
Bring next digit (7) of the dividend behind the 147 and repeat the process: 1477 / 687

Moving on to step 5:
687 goes into 1477 2 times with a remainder of 103.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we take 1374 away from 1477, we end up with 103.
Include the next digit (9) from the dividend after 103, then repeat: 1039 / 687

On to step 6:
When dividing 1039 by 687, we get 1 with a remainder of 352.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
Subtract 687 from 1039 to get 352.
Bring next digit (4) of the dividend behind the 352 and repeat the process: 3524 / 687

Moving on to step 7:
If we divide 3524 by 687, we get 5 and a remainder of 89.
Write down 5 as next digit of the result. 
Result so far: 3215.0
If we subtract 3435 from 3524, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 8:
687 can be fit into 890 1 times, resulting in a remainder of 203.
Put 1 as the next digit of the answer. 
Result so far: 3215.1
If we subtract 687 from 890, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 9:
687 can be fit into 2030 2 times, resulting in a remainder of 656.
The number 2 becomes the next digit in our result. 
Result so far: 3215.12
The remainder is 656 after subtracting 1374 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Step 10:
The number 687 fits into 6560 9 times, leaving a remainder of 377.
Use 9 as the next digit of our solution. 
Result so far: 3215.129
If we take 6183 away from 6560, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

On to step 11:
687 goes into 3770 5 times with a remainder of 335.
The number 5 becomes the next digit in our result. 
Result so far: 3215.1295
Subtracting 3435 from 3770 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 12:
3350 divided by 687 is 4 with a remainder of 602.
Put 4 as the next digit of the answer. 
Result so far: 3215.12954
Subtract 2748 from 3350 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Going ahead to step 13:
6020 divided by 687 is 8 with a remainder of 524.
Use 8 as the next digit of our solution. 
Result so far: 3215.129548
The remainder is 524 after subtracting 5496 from 6020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 14:
5240 divided by 687 is 7 with a remainder of 431.
Record the quotient 7 as the next digit in the result. 
Result so far: 3215.1295487
Deduct 4809 from 5240 and we're left with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Advancing to step 15:
When dividing 4310 by 687, we get 6 with a remainder of 188.
The number 6 becomes the next digit in our result. 
Result so far: 3215.12954876
Deduct 4122 from 4310 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

The final outcome is 3215.12954876, with a leftover of 1.88e-07.
