We divide 84547 by 90
We want to figure out the number of times 84547 can be divided by 90.

Step 1:
When dividing 8 by 90, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 90

On to step 2:
90 goes into 84 0 times with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Fetch the next digit (5) from the dividend, attach it to 84 and continue: 845 / 90

On to step 3:
845 divided by 90 is 9 with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 810 away from 845, we end up with 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 90

Advancing to step 4:
The number 90 fits into 354 3 times, leaving a remainder of 84.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Deduct 270 from 354 and we're left with 84.
Take the next digit (7) from the dividend and append it to 84, then repeat: 847 / 90

Step 5:
When dividing 847 by 90, we get 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 939.0
Subtract 810 from 847 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 6:
90 goes into 370 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 939.4
If we take 360 away from 370, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
When dividing 100 by 90, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 939.41
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 90, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 939.411
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.

The final result is 939.411 with a remainder of 0.001.
