81699402 divided by 8 
We want to figure out the number of times 81699402 can be divided by 8.

Moving on to step 1:
If we divide 8 by 8, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 8 away from 8, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 8

Step 2:
If we divide 1 by 8, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 8

Going ahead to step 3:
16 divided by 8 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we subtract 16 from 16, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 8

Moving on to step 4:
9 divided by 8 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1021.0
If we take 8 away from 9, we end up with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 8

On to step 5:
If we divide 19 by 8, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 10212.0
Deduct 16 from 19 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 8

On to step 6:
34 divided by 8 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 102124.0
Subtract 32 from 34 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 8

On to step 7:
8 can be fit into 20 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1021242.0
If we subtract 16 from 20, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 8

Moving on to step 8:
42 divided by 8 is 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 10212425.0
If we take 40 away from 42, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
If we divide 20 by 8, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 10212425.2
Subtracting 16 from 20 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 8 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10212425.25
Deduct 40 from 40 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
8 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10212425.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
8 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10212425.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 10212425.25 with a balance of 0.0.
