We're dividing 85699642 by 8 
Our goal is to divide 85699642 by 8.

Advancing to step 1:
8 can be fit into 8 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 8

On to step 2:
If we divide 5 by 8, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 5, we end up with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 8

Going ahead to step 3:
The number 8 fits into 56 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 107.0
The remainder is 0 after subtracting 56 from 56.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 8

Going ahead to step 4:
8 goes into 9 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1071.0
If we take 8 away from 9, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 8

On to step 5:
The number 8 fits into 19 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 10712.0
Subtract 16 from 19 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 8

Advancing to step 6:
36 divided by 8 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 107124.0
Deduct 32 from 36 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 8

Step 7:
The number 8 fits into 44 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 1071245.0
If we subtract 40 from 44, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 8

Advancing to step 8:
8 can be fit into 42 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 10712455.0
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.

Step 9:
8 goes into 20 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 10712455.2
Deduct 16 from 20 and we're left 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.

Advancing to step 10:
If we divide 40 by 8, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10712455.25
If we take 40 away from 40, we end up 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.

On to step 11:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10712455.25
If we take 0 away from 0, we end up 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.

On to step 12:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10712455.25
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.

The final outcome is 10712455.25, with a leftover of 0.0.
