26502124 divided by 688 
The aim is to understand the frequency of 688 in 26502124.

Step 1:
2 divided by 688 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 688

Going ahead to step 2:
The number 688 fits into 26 0 times, leaving a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 688

On to step 3:
The number 688 fits into 265 0 times, leaving a remainder of 265.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 265, we end up with 265.
Take the next digit (0) from the dividend and append it to 265, then repeat: 2650 / 688

Let's proceed to step 4:
When dividing 2650 by 688, we get 3 with a remainder of 586.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2064 from 2650, we get 586.
Bring next digit (2) of the dividend behind the 586 and repeat the process: 5862 / 688

Moving on to step 5:
5862 divided by 688 is 8 with a remainder of 358.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
The remainder is 358 after subtracting 5504 from 5862.
Bring next digit (1) of the dividend behind the 358 and repeat the process: 3581 / 688

Step 6:
If we divide 3581 by 688, we get 5 and a remainder of 141.
The next digit of our result is 5. 
Result so far: 385.0
The remainder is 141 after subtracting 3440 from 3581.
Append the next digit (2) from the dividend to 141 and continue with: 1412 / 688

Let's proceed to step 7:
688 goes into 1412 2 times with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 3852.0
Subtract 1376 from 1412 to get 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 688

Let's proceed to step 8:
364 divided by 688 is 0 with a remainder of 364.
The number 0 becomes the next digit in our result. 
Result so far: 38520.0
If we take 0 away from 364, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 9:
The number 688 fits into 3640 5 times, leaving a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 38520.5
Subtracting 3440 from 3640 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
When dividing 2000 by 688, we get 2 with a remainder of 624.
The next digit of our result is 2. 
Result so far: 38520.52
If we take 1376 away from 2000, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

On to step 11:
6240 divided by 688 is 9 with a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 38520.529
The remainder is 48 after subtracting 6192 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
688 can be fit into 480 0 times, resulting in a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 38520.529
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 13:
The number 688 fits into 4800 6 times, leaving a remainder of 672.
Put 6 as the next digit of the answer. 
Result so far: 38520.52906
If we subtract 4128 from 4800, we get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Advancing to step 14:
If we divide 6720 by 688, we get 9 and a remainder of 528.
The next digit of our result is 9. 
Result so far: 38520.529069
If we subtract 6192 from 6720, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 15:
688 can be fit into 5280 7 times, resulting in a remainder of 464.
Use 7 as the next digit of our solution. 
Result so far: 38520.5290697
The remainder is 464 after subtracting 4816 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 16:
If we divide 4640 by 688, we get 6 and a remainder of 512.
Put 6 as the next digit of the answer. 
Result so far: 38520.52906976
Deduct 4128 from 4640 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Our division results in 38520.52906976 with a remaining 5.12e-07.
