We're dividing 593991 by 99 
We're looking to find how many times 99 goes into 593991.

Moving on to step 1:
The number 99 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 99

Advancing to step 2:
59 divided by 99 is 0 with a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 99

On to step 3:
99 goes into 593 5 times with a remainder of 98.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 495 from 593, we get 98.
Append the next digit (9) from the dividend to 98 and continue with: 989 / 99

Advancing to step 4:
99 can be fit into 989 9 times, resulting in a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Deduct 891 from 989 and we're left with 98.
Grab the next digit (9) from the dividend, add it to 98, then carry on: 989 / 99

Moving on to step 5:
99 goes into 989 9 times with a remainder of 98.
Put 9 as the next digit of the answer. 
Result so far: 599.0
If we subtract 891 from 989, we get 98.
Grab the next digit (1) from the dividend, add it to 98, then carry on: 981 / 99

Going ahead to step 6:
The number 99 fits into 981 9 times, leaving a remainder of 90.
The number 9 becomes the next digit in our result. 
Result so far: 5999.0
If we subtract 891 from 981, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 7:
99 goes into 900 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 5999.9
If we take 891 away from 900, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
99 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 5999.9
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 9:
When dividing 900 by 99, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 5999.909
If we subtract 891 from 900, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
99 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 5999.909
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
99 goes into 900 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 5999.90909
Subtract 891 from 900 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
99 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 5999.90909
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
99 can be fit into 900 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 5999.9090909
If we take 891 away from 900, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
90 divided by 99 is 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 5999.9090909
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 5999.9090909, with a leftover of 9e-08.
