Let's divide 163402 by 90
We're looking to find how many times 90 goes into 163402.

Step 1:
1 divided by 90 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 90

Let's proceed to step 2:
90 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 90

Moving on to step 3:
The number 90 fits into 163 1 times, leaving a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 73 after subtracting 90 from 163.
Take the next digit (4) from the dividend and append it to 73, then repeat: 734 / 90

Step 4:
90 can be fit into 734 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 720 from 734 leaves us with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 90

Let's proceed to step 5:
140 divided by 90 is 1 with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 181.0
If we take 90 away from 140, we end up with 50.
Grab the next digit (2) from the dividend, add it to 50, then carry on: 502 / 90

Going ahead to step 6:
90 goes into 502 5 times with a remainder of 52.
Write down 5 as next digit of the result. 
Result so far: 1815.0
If we take 450 away from 502, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 7:
520 divided by 90 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 1815.5
If we take 450 away from 520, 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.

On to step 8:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 1815.57
Subtracting 630 from 700 leaves us 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 9:
If we divide 700 by 90, we get 7 and a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 1815.577
Subtract 630 from 700 to get 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 1815.577, and the remainder is 0.007.
