Let's divide 89451053 by 816
We want to divide 89451053 by 816.

Advancing to step 1:
The number 816 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 816

Going ahead to step 2:
The number 816 fits into 89 0 times, leaving a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Bring next digit (4) of the dividend behind the 89 and repeat the process: 894 / 816

On to step 3:
894 divided by 816 is 1 with a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 816 away from 894, we end up with 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 816

Step 4:
The number 816 fits into 785 0 times, leaving a remainder of 785.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 785 to get 785.
Append the next digit (1) from the dividend to 785 and continue with: 7851 / 816

Step 5:
The number 816 fits into 7851 9 times, leaving a remainder of 507.
The next digit of our result is 9. 
Result so far: 109.0
If we take 7344 away from 7851, we end up with 507.
Take the next digit (0) from the dividend and append it to 507, then repeat: 5070 / 816

Step 6:
The number 816 fits into 5070 6 times, leaving a remainder of 174.
The number 6 becomes the next digit in our result. 
Result so far: 1096.0
If we take 4896 away from 5070, we end up with 174.
Bring next digit (5) of the dividend behind the 174 and repeat the process: 1745 / 816

Let's proceed to step 7:
The number 816 fits into 1745 2 times, leaving a remainder of 113.
The number 2 becomes the next digit in our result. 
Result so far: 10962.0
Subtract 1632 from 1745 to get 113.
Append the next digit (3) from the dividend to 113 and continue with: 1133 / 816

Going ahead to step 8:
The number 816 fits into 1133 1 times, leaving a remainder of 317.
Put 1 as the next digit of the answer. 
Result so far: 109621.0
If we take 816 away from 1133, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 9:
If we divide 3170 by 816, we get 3 and a remainder of 722.
The next digit of our result is 3. 
Result so far: 109621.3
If we take 2448 away from 3170, we end up with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Advancing to step 10:
When dividing 7220 by 816, we get 8 with a remainder of 692.
The next digit of our result is 8. 
Result so far: 109621.38
The remainder is 692 after subtracting 6528 from 7220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Let's proceed to step 11:
When dividing 6920 by 816, we get 8 with a remainder of 392.
The number 8 becomes the next digit in our result. 
Result so far: 109621.388
The remainder is 392 after subtracting 6528 from 6920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

After the division, we end up with 109621.388 and a remainder of 0.0392.
