We divide 213225 by 99
We want to figure out the number of times 213225 can be divided by 99.

Step 1:
2 divided by 99 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 99

Moving on to step 2:
99 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 99

On to step 3:
99 can be fit into 213 2 times, resulting in a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 198 from 213 to get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 99

On to step 4:
When dividing 152 by 99, we get 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 99 from 152 to get 53.
Take the next digit (2) from the dividend and append it to 53, then repeat: 532 / 99

Moving on to step 5:
If we divide 532 by 99, we get 5 and a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 215.0
The remainder is 37 after subtracting 495 from 532.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 99

Moving on to step 6:
The number 99 fits into 375 3 times, leaving a remainder of 78.
Record the quotient 3 as the next digit in the result. 
Result so far: 2153.0
If we subtract 297 from 375, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 7:
The number 99 fits into 780 7 times, leaving a remainder of 87.
The next digit of our result is 7. 
Result so far: 2153.7
Subtracting 693 from 780 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 8:
The number 99 fits into 870 8 times, leaving a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 2153.78
Subtracting 792 from 870 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 9:
99 goes into 780 7 times with a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 2153.787
If we subtract 693 from 780, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 10:
When dividing 870 by 99, we get 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 2153.7878
If we subtract 792 from 870, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 11:
The number 99 fits into 780 7 times, leaving a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 2153.78787
If we take 693 away from 780, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 12:
99 can be fit into 870 8 times, resulting in a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 2153.787878
If we subtract 792 from 870, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 13:
780 divided by 99 is 7 with a remainder of 87.
The next digit of our result is 7. 
Result so far: 2153.7878787
If we subtract 693 from 780, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 14:
If we divide 870 by 99, we get 8 and a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 2153.78787878
Subtracting 792 from 870 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 2153.78787878 and a remainder of 7.8e-08.
