1768888 divided by 688 
The aim is to understand the frequency of 688 in 1768888.

Step 1:
When dividing 1 by 688, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 688

Step 2:
688 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 688

Going ahead to step 3:
688 goes into 176 0 times with a remainder of 176.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 176 to get 176.
Append the next digit (8) from the dividend to 176 and continue with: 1768 / 688

Let's proceed to step 4:
The number 688 fits into 1768 2 times, leaving a remainder of 392.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1376 from 1768 to get 392.
Fetch the next digit (8) from the dividend, attach it to 392 and continue: 3928 / 688

Moving on to step 5:
3928 divided by 688 is 5 with a remainder of 488.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 3440 from 3928 leaves us with 488.
Append the next digit (8) from the dividend to 488 and continue with: 4888 / 688

Advancing to step 6:
When dividing 4888 by 688, we get 7 with a remainder of 72.
Put 7 as the next digit of the answer. 
Result so far: 257.0
Subtract 4816 from 4888 to get 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 688

Step 7:
The number 688 fits into 728 1 times, leaving a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 2571.0
If we subtract 688 from 728, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
When dividing 400 by 688, we get 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 2571.0
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 9:
4000 divided by 688 is 5 with a remainder of 560.
Record the quotient 5 as the next digit in the result. 
Result so far: 2571.05
If we subtract 3440 from 4000, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 10:
5600 divided by 688 is 8 with a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 2571.058
If we subtract 5504 from 5600, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 11:
688 can be fit into 960 1 times, resulting in a remainder of 272.
The number 1 becomes the next digit in our result. 
Result so far: 2571.0581
Subtract 688 from 960 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 12:
2720 divided by 688 is 3 with a remainder of 656.
Use 3 as the next digit of our solution. 
Result so far: 2571.05813
If we take 2064 away from 2720, we end up with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

On to step 13:
The number 688 fits into 6560 9 times, leaving a remainder of 368.
Write down 9 as next digit of the result. 
Result so far: 2571.058139
Subtracting 6192 from 6560 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 14:
688 goes into 3680 5 times with a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 2571.0581395
The remainder is 240 after subtracting 3440 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 15:
2400 divided by 688 is 3 with a remainder of 336.
Put 3 as the next digit of the answer. 
Result so far: 2571.05813953
Subtract 2064 from 2400 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Our division results in 2571.05813953 with a remaining 3.36e-07.
