90309 divided by 53 
Our goal is to divide 90309 by 53.

Advancing to step 1:
If we divide 9 by 53, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 53

Let's proceed to step 2:
The number 53 fits into 90 1 times, leaving a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 53 away from 90, we end up with 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 53

Moving on to step 3:
53 can be fit into 373 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 371 from 373 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 53

On to step 4:
53 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 53

Step 5:
If we divide 209 by 53, we get 3 and a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 1703.0
Subtract 159 from 209 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 6:
500 divided by 53 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 1703.9
If we subtract 477 from 500, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
When dividing 230 by 53, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 1703.94
Subtracting 212 from 230 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
When dividing 180 by 53, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 1703.943
Subtract 159 from 180 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
When dividing 210 by 53, we get 3 with a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 1703.9433
Subtract 159 from 210 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 1703.9433 and a remainder of 0.00051.
