We're dividing 76448282 by 688 
The aim is to understand the frequency of 688 in 76448282.

Step 1:
7 divided by 688 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 688

Let's proceed to step 2:
688 goes into 76 0 times with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 688

Step 3:
688 can be fit into 764 1 times, resulting in a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 76 after subtracting 688 from 764.
Take the next digit (4) from the dividend and append it to 76, then repeat: 764 / 688

Going ahead to step 4:
When dividing 764 by 688, we get 1 with a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 688 from 764 to get 76.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 688

Advancing to step 5:
If we divide 768 by 688, we get 1 and a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
If we subtract 688 from 768, we get 80.
Bring next digit (2) of the dividend behind the 80 and repeat the process: 802 / 688

Advancing to step 6:
802 divided by 688 is 1 with a remainder of 114.
The next digit of our result is 1. 
Result so far: 1111.0
The remainder is 114 after subtracting 688 from 802.
Bring next digit (8) of the dividend behind the 114 and repeat the process: 1148 / 688

Advancing to step 7:
1148 divided by 688 is 1 with a remainder of 460.
Use 1 as the next digit of our solution. 
Result so far: 11111.0
Deduct 688 from 1148 and we're left with 460.
Grab the next digit (2) from the dividend, add it to 460, then carry on: 4602 / 688

Advancing to step 8:
4602 divided by 688 is 6 with a remainder of 474.
Put 6 as the next digit of the answer. 
Result so far: 111116.0
If we subtract 4128 from 4602, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Advancing to step 9:
688 can be fit into 4740 6 times, resulting in a remainder of 612.
The number 6 becomes the next digit in our result. 
Result so far: 111116.6
The remainder is 612 after subtracting 4128 from 4740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Moving on to step 10:
If we divide 6120 by 688, we get 8 and a remainder of 616.
Use 8 as the next digit of our solution. 
Result so far: 111116.68
If we take 5504 away from 6120, we end up with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 11:
When dividing 6160 by 688, we get 8 with a remainder of 656.
The number 8 becomes the next digit in our result. 
Result so far: 111116.688
The remainder is 656 after subtracting 5504 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Our division results in 111116.688 with a remaining 0.0656.
