The aim is to understand the frequency of 888 in 68016600.

On to step 1:
6 divided by 888 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 888

Step 2:
If we divide 68 by 888, we get 0 and a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Append the next digit (0) from the dividend to 68 and continue with: 680 / 888

Advancing to step 3:
When dividing 680 by 888, we get 0 with a remainder of 680.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 680, we get 680.
Include the next digit (1) from the dividend after 680, then repeat: 6801 / 888

Step 4:
888 goes into 6801 7 times with a remainder of 585.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 6216 from 6801 and we're left with 585.
Include the next digit (6) from the dividend after 585, then repeat: 5856 / 888

Let's proceed to step 5:
5856 divided by 888 is 6 with a remainder of 528.
The next digit of our result is 6. 
Result so far: 76.0
If we take 5328 away from 5856, we end up with 528.
Fetch the next digit (6) from the dividend, attach it to 528 and continue: 5286 / 888

Step 6:
When dividing 5286 by 888, we get 5 with a remainder of 846.
Write down 5 as next digit of the result. 
Result so far: 765.0
Subtracting 4440 from 5286 leaves us with 846.
Include the next digit (0) from the dividend after 846, then repeat: 8460 / 888

Advancing to step 7:
888 can be fit into 8460 9 times, resulting in a remainder of 468.
The number 9 becomes the next digit in our result. 
Result so far: 7659.0
Deduct 7992 from 8460 and we're left with 468.
Fetch the next digit (0) from the dividend, attach it to 468 and continue: 4680 / 888

Going ahead to step 8:
888 goes into 4680 5 times with a remainder of 240.
Record the quotient 5 as the next digit in the result. 
Result so far: 76595.0
The remainder is 240 after subtracting 4440 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 9:
When dividing 2400 by 888, we get 2 with a remainder of 624.
Use 2 as the next digit of our solution. 
Result so far: 76595.2
Deduct 1776 from 2400 and we're left 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.

Going ahead to step 10:
6240 divided by 888 is 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 76595.27
If we subtract 6216 from 6240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
240 divided by 888 is 0 with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 76595.27
Subtracting 0 from 240 leaves us with 240.
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 12:
The number 888 fits into 2400 2 times, leaving a remainder of 624.
Record the quotient 2 as the next digit in the result. 
Result so far: 76595.2702
If we take 1776 away from 2400, 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.

Moving on to step 13:
6240 divided by 888 is 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 76595.27027
If we take 6216 away from 6240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
If we divide 240 by 888, we get 0 and a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 76595.27027
If we subtract 0 from 240, we 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.

On to step 15:
The number 888 fits into 2400 2 times, leaving a remainder of 624.
The number 2 becomes the next digit in our result. 
Result so far: 76595.2702702
Subtract 1776 from 2400 to get 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 16:
If we divide 6240 by 888, we get 7 and a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 76595.27027027
If we subtract 6216 from 6240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 76595.27027027 with a remaining 2.4e-08.
