539661 divided by 99 
We want to figure out the number of times 539661 can be divided by 99.

Moving on to step 1:
The number 99 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 99

Let's proceed to step 2:
When dividing 53 by 99, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 99

Moving on to step 3:
99 can be fit into 539 5 times, resulting in a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 495 away from 539, we end up with 44.
Grab the next digit (6) from the dividend, add it to 44, then carry on: 446 / 99

On to step 4:
When dividing 446 by 99, we get 4 with a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtracting 396 from 446 leaves us with 50.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 99

Advancing to step 5:
If we divide 506 by 99, we get 5 and a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 545.0
Deduct 495 from 506 and we're left with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 99

On to step 6:
When dividing 111 by 99, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 5451.0
The remainder is 12 after subtracting 99 from 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
120 divided by 99 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 5451.1
The remainder is 21 after subtracting 99 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
The number 99 fits into 210 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 5451.12
If we take 198 away from 210, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
The number 99 fits into 120 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 5451.121
Deduct 99 from 120 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 10:
When dividing 210 by 99, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 5451.1212
Subtract 198 from 210 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
The number 99 fits into 120 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 5451.12121
The remainder is 21 after subtracting 99 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 12:
210 divided by 99 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 5451.121212
If we take 198 away from 210, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
When dividing 120 by 99, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 5451.1212121
Subtract 99 from 120 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.

Advancing to step 14:
When dividing 210 by 99, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 5451.12121212
If we subtract 198 from 210, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 5451.12121212 with a remainder of 1.2e-08.
