We look at the division of 84493 by 90 
We want to figure out the number of times 84493 can be divided by 90.

On to step 1:
When dividing 8 by 90, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 90

Let's proceed to step 2:
90 can be fit into 84 0 times, resulting in a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Fetch the next digit (4) from the dividend, attach it to 84 and continue: 844 / 90

Step 3:
When dividing 844 by 90, we get 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 810 from 844, we get 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 90

Moving on to step 4:
90 goes into 349 3 times with a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we take 270 away from 349, we end up with 79.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 90

Advancing to step 5:
90 can be fit into 793 8 times, resulting in a remainder of 73.
Put 8 as the next digit of the answer. 
Result so far: 938.0
Subtract 720 from 793 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 6:
90 goes into 730 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 938.8
If we subtract 720 from 730, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
When dividing 100 by 90, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 938.81
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 938.811
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 938.811 with a remaining 0.001.
