We look at the division of 81128070 by 90 
We want to divide 81128070 by 90.

On to step 1:
8 divided by 90 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 90

Let's proceed to step 2:
81 divided by 90 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 90

Step 3:
811 divided by 90 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 810 away from 811, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 90

Step 4:
12 divided by 90 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 90.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 90

Advancing to step 5:
When dividing 128 by 90, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 901.0
Deduct 90 from 128 and we're left with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 90

Let's proceed to step 6:
90 can be fit into 380 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 9014.0
The remainder is 20 after subtracting 360 from 380.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 90

Advancing to step 7:
When dividing 207 by 90, we get 2 with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 90142.0
If we take 180 away from 207, we end up with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 90

Let's proceed to step 8:
When dividing 270 by 90, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 901423.0
Subtract 270 from 270 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.

Moving on to step 9:
90 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 901423.0
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.

Moving on to step 10:
The number 90 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 901423.0
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 quotient of the division is 901423.0, and the remainder is 0.0.
