61391 ÷ 99 
Our goal is to divide 61391 by 99.

Going ahead to step 1:
When dividing 6 by 99, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 99

Going ahead to step 2:
99 goes into 61 0 times with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Include the next digit (3) from the dividend after 61, then repeat: 613 / 99

Going ahead to step 3:
99 can be fit into 613 6 times, resulting in a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 594 from 613 to get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 99

Moving on to step 4:
99 can be fit into 199 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Subtracting 198 from 199 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 99

On to step 5:
99 can be fit into 11 0 times, resulting in a remainder of 11.
The next digit of our result is 0. 
Result so far: 620.0
Subtracting 0 from 11 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 6:
If we divide 110 by 99, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 620.1
Deduct 99 from 110 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 99 fits into 110 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 620.11
Deduct 99 from 110 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 620.11 with a remainder of 0.011.
