We're dividing 525621 by 99 
We want to figure out the number of times 525621 can be divided by 99.

On to step 1:
When dividing 5 by 99, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 99

Advancing to step 2:
99 goes into 52 0 times with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 99

Step 3:
99 can be fit into 525 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 495 away from 525, we end up with 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 99

On to step 4:
99 goes into 306 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtracting 297 from 306 leaves us with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 99

Let's proceed to step 5:
If we divide 92 by 99, we get 0 and a remainder of 92.
The next digit of our result is 0. 
Result so far: 530.0
Subtract 0 from 92 to get 92.
Grab the next digit (1) from the dividend, add it to 92, then carry on: 921 / 99

Step 6:
If we divide 921 by 99, we get 9 and a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 5309.0
Subtracting 891 from 921 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
300 divided by 99 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 5309.3
Deduct 297 from 300 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
30 divided by 99 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 5309.3
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
300 divided by 99 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 5309.303
If we take 297 away from 300, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
30 divided by 99 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 5309.303
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
300 divided by 99 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 5309.30303
If we subtract 297 from 300, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
99 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 5309.30303
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
300 divided by 99 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 5309.3030303
The remainder is 3 after subtracting 297 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
When dividing 30 by 99, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 5309.3030303
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 5309.3030303 and a remainder of 3e-08.
