Let's divide 164689 by 90
Our goal is to divide 164689 by 90.

Let's proceed to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 90

Advancing to step 2:
90 goes into 16 0 times with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 90

Step 3:
164 divided by 90 is 1 with a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 90 away from 164, we end up with 74.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 90

Going ahead to step 4:
The number 90 fits into 746 8 times, leaving a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 720 from 746 and we're left with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 90

Moving on to step 5:
268 divided by 90 is 2 with a remainder of 88.
The next digit of our result is 2. 
Result so far: 182.0
Deduct 180 from 268 and we're left with 88.
Fetch the next digit (9) from the dividend, attach it to 88 and continue: 889 / 90

Moving on to step 6:
90 can be fit into 889 9 times, resulting in a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 1829.0
If we subtract 810 from 889, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 7:
The number 90 fits into 790 8 times, leaving a remainder of 70.
The next digit of our result is 8. 
Result so far: 1829.8
If we take 720 away from 790, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
If we divide 700 by 90, we get 7 and a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 1829.87
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
90 goes into 700 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 1829.877
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 1829.877, and the remainder is 0.007.
