73402 divided by 90 
We want to divide 73402 by 90.

On to step 1:
90 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 90

On to step 2:
When dividing 73 by 90, we get 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Include the next digit (4) from the dividend after 73, then repeat: 734 / 90

Step 3:
If we divide 734 by 90, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 720 from 734 to get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 90

Moving on to step 4:
When dividing 140 by 90, we get 1 with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we take 90 away from 140, we end up with 50.
Take the next digit (2) from the dividend and append it to 50, then repeat: 502 / 90

Going ahead to step 5:
90 can be fit into 502 5 times, resulting in a remainder of 52.
Record the quotient 5 as the next digit in the result. 
Result so far: 815.0
Subtracting 450 from 502 leaves us 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 6:
When dividing 520 by 90, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 815.5
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.

Let's proceed to step 7:
700 divided by 90 is 7 with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 815.57
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.

Advancing to step 8:
The number 90 fits into 700 7 times, leaving a remainder of 70.
The next digit of our result is 7. 
Result so far: 815.577
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.

The final result is 815.577 with a remainder of 0.007.
