We look at the division of 128090 by 8 
We're looking to find how many times 8 goes into 128090.

On to step 1:
The number 8 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 8

Moving on to step 2:
8 can be fit into 12 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 8 from 12 to get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 8

Step 3:
8 goes into 48 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 48 from 48 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 8

On to step 4:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 160.0
If we subtract 0 from 0, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 8

Step 5:
If we divide 9 by 8, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1601.0
If we subtract 8 from 9, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 8

Moving on to step 6:
When dividing 10 by 8, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 16011.0
Deduct 8 from 10 and we're left 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 7:
8 can be fit into 20 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 16011.2
Subtract 16 from 20 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
40 divided by 8 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 16011.25
Subtracting 40 from 40 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.

On to step 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16011.25
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.

Advancing to step 10:
0 divided by 8 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16011.25
Subtract 0 from 0 to get 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 quotient of the division is 16011.25, and the remainder is 0.0.
