30561 ÷ 91 
We want to divide 30561 by 91.

Step 1:
91 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 91

Step 2:
91 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 91

On to step 3:
If we divide 305 by 91, we get 3 and a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 273 away from 305, we end up with 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 91

Let's proceed to step 4:
If we divide 326 by 91, we get 3 and a remainder of 53.
The next digit of our result is 3. 
Result so far: 33.0
Deduct 273 from 326 and we're left with 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 91

Moving on to step 5:
The number 91 fits into 531 5 times, leaving a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 335.0
Subtracting 455 from 531 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 6:
91 goes into 760 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 335.8
If we take 728 away from 760, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
If we divide 320 by 91, we get 3 and a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 335.83
The remainder is 47 after subtracting 273 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 8:
470 divided by 91 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 335.835
If we take 455 away from 470, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
When dividing 150 by 91, we get 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 335.8351
Subtract 91 from 150 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 10:
91 can be fit into 590 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 335.83516
Subtracting 546 from 590 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
When dividing 440 by 91, we get 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 335.835164
If we take 364 away from 440, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
91 can be fit into 760 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 335.8351648
If we take 728 away from 760, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
320 divided by 91 is 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 335.83516483
The remainder is 47 after subtracting 273 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Our division results in 335.83516483 with a remaining 4.7e-08.
