We look at the division of 85335095 by 688 
The aim is to understand the frequency of 688 in 85335095.

On to step 1:
The number 688 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 688

Let's proceed to step 2:
If we divide 85 by 688, we get 0 and a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Take the next digit (3) from the dividend and append it to 85, then repeat: 853 / 688

Advancing to step 3:
853 divided by 688 is 1 with a remainder of 165.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 688 away from 853, we end up with 165.
Bring next digit (3) of the dividend behind the 165 and repeat the process: 1653 / 688

Moving on to step 4:
688 can be fit into 1653 2 times, resulting in a remainder of 277.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1376 from 1653 to get 277.
Take the next digit (5) from the dividend and append it to 277, then repeat: 2775 / 688

Moving on to step 5:
688 can be fit into 2775 4 times, resulting in a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we take 2752 away from 2775, we end up with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 688

Advancing to step 6:
230 divided by 688 is 0 with a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 1240.0
Subtracting 0 from 230 leaves us with 230.
Take the next digit (9) from the dividend and append it to 230, then repeat: 2309 / 688

On to step 7:
2309 divided by 688 is 3 with a remainder of 245.
Use 3 as the next digit of our solution. 
Result so far: 12403.0
If we subtract 2064 from 2309, we get 245.
Take the next digit (5) from the dividend and append it to 245, then repeat: 2455 / 688

Advancing to step 8:
2455 divided by 688 is 3 with a remainder of 391.
The number 3 becomes the next digit in our result. 
Result so far: 124033.0
Subtract 2064 from 2455 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Step 9:
688 can be fit into 3910 5 times, resulting in a remainder of 470.
Put 5 as the next digit of the answer. 
Result so far: 124033.5
If we subtract 3440 from 3910, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 10:
The number 688 fits into 4700 6 times, leaving a remainder of 572.
Write down 6 as next digit of the result. 
Result so far: 124033.56
If we take 4128 away from 4700, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Going ahead to step 11:
If we divide 5720 by 688, we get 8 and a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 124033.568
Subtracting 5504 from 5720 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 12:
When dividing 2160 by 688, we get 3 with a remainder of 96.
Use 3 as the next digit of our solution. 
Result so far: 124033.5683
If we subtract 2064 from 2160, 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 13:
The number 688 fits into 960 1 times, leaving a remainder of 272.
The next digit of our result is 1. 
Result so far: 124033.56831
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.

Going ahead to step 14:
688 can be fit into 2720 3 times, resulting in a remainder of 656.
Write down 3 as next digit of the result. 
Result so far: 124033.568313
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.

Step 15:
The number 688 fits into 6560 9 times, leaving a remainder of 368.
The number 9 becomes the next digit in our result. 
Result so far: 124033.5683139
If we subtract 6192 from 6560, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 16:
When dividing 3680 by 688, we get 5 with a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 124033.56831395
Subtract 3440 from 3680 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final outcome is 124033.56831395, with a leftover of 2.4e-07.
