We're dividing 143484 by 90 
We're looking to find how many times 90 goes into 143484.

Step 1:
90 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 90

Moving on to step 2:
If we divide 14 by 90, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 90

Let's proceed to step 3:
90 goes into 143 1 times with a remainder of 53.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 90 from 143 leaves us with 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 90

Going ahead to step 4:
90 can be fit into 534 5 times, resulting in a remainder of 84.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 450 from 534 to get 84.
Include the next digit (8) from the dividend after 84, then repeat: 848 / 90

On to step 5:
90 goes into 848 9 times with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 159.0
Subtract 810 from 848 to get 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 90

Moving on to step 6:
When dividing 384 by 90, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 1594.0
If we subtract 360 from 384, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
If we divide 240 by 90, we get 2 and a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 1594.2
If we subtract 180 from 240, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 1594.26
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
If we divide 600 by 90, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 1594.266
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 1594.266, and the remainder is 0.006.
