89873013 ÷ 452 
We want to figure out the number of times 89873013 can be divided by 452.

Advancing to step 1:
The number 452 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 452

Let's proceed to step 2:
452 can be fit into 89 0 times, resulting in a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Include the next digit (8) from the dividend after 89, then repeat: 898 / 452

On to step 3:
452 can be fit into 898 1 times, resulting in a remainder of 446.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 452 from 898 to get 446.
Append the next digit (7) from the dividend to 446 and continue with: 4467 / 452

On to step 4:
4467 divided by 452 is 9 with a remainder of 399.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 4068 from 4467, we get 399.
Bring next digit (3) of the dividend behind the 399 and repeat the process: 3993 / 452

Moving on to step 5:
If we divide 3993 by 452, we get 8 and a remainder of 377.
The next digit of our result is 8. 
Result so far: 198.0
Deduct 3616 from 3993 and we're left with 377.
Fetch the next digit (0) from the dividend, attach it to 377 and continue: 3770 / 452

Going ahead to step 6:
The number 452 fits into 3770 8 times, leaving a remainder of 154.
Write down 8 as next digit of the result. 
Result so far: 1988.0
If we take 3616 away from 3770, we end up with 154.
Take the next digit (1) from the dividend and append it to 154, then repeat: 1541 / 452

Advancing to step 7:
452 can be fit into 1541 3 times, resulting in a remainder of 185.
The next digit of our result is 3. 
Result so far: 19883.0
If we subtract 1356 from 1541, we get 185.
Fetch the next digit (3) from the dividend, attach it to 185 and continue: 1853 / 452

Step 8:
452 goes into 1853 4 times with a remainder of 45.
Use 4 as the next digit of our solution. 
Result so far: 198834.0
The remainder is 45 after subtracting 1808 from 1853.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
If we divide 450 by 452, we get 0 and a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 198834.0
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 10:
The number 452 fits into 4500 9 times, leaving a remainder of 432.
The next digit of our result is 9. 
Result so far: 198834.09
Subtracting 4068 from 4500 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 11:
452 goes into 4320 9 times with a remainder of 252.
Use 9 as the next digit of our solution. 
Result so far: 198834.099
Subtract 4068 from 4320 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

After the division, we end up with 198834.099 and a remainder of 0.0252.
