We're dividing 84490488 by 90 
Our goal is to divide 84490488 by 90.

Step 1:
The number 90 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 90

Moving on to step 2:
90 goes into 84 0 times with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Take the next digit (4) from the dividend and append it to 84, then repeat: 844 / 90

Let's proceed to step 3:
844 divided by 90 is 9 with a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 810 from 844 to get 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 90

Advancing to step 4:
When dividing 349 by 90, we get 3 with a remainder of 79.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtracting 270 from 349 leaves us with 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 90

Advancing to step 5:
The number 90 fits into 790 8 times, leaving a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 938.0
Deduct 720 from 790 and we're left with 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 90

Going ahead to step 6:
90 goes into 704 7 times with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 9387.0
Deduct 630 from 704 and we're left with 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 90

Advancing to step 7:
90 can be fit into 748 8 times, resulting in a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 93878.0
The remainder is 28 after subtracting 720 from 748.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 90

Let's proceed to step 8:
The number 90 fits into 288 3 times, leaving a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 938783.0
If we take 270 away from 288, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
When dividing 180 by 90, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 938783.2
Subtracting 180 from 180 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.

Let's proceed to step 10:
90 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 938783.2
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.

Going ahead to step 11:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 938783.2
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 result is 938783.2 with a remainder of 0.0.
