Let's divide 90080581 by 816
Our goal is to divide 90080581 by 816.

On to step 1:
The number 816 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 816

Step 2:
When dividing 90 by 816, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Bring next digit (0) of the dividend behind the 90 and repeat the process: 900 / 816

Let's proceed to step 3:
If we divide 900 by 816, we get 1 and a remainder of 84.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 84 after subtracting 816 from 900.
Fetch the next digit (8) from the dividend, attach it to 84 and continue: 848 / 816

Going ahead to step 4:
848 divided by 816 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 816 from 848 and we're left with 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 816

Step 5:
816 goes into 320 0 times with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 110.0
If we subtract 0 from 320, we get 320.
Include the next digit (5) from the dividend after 320, then repeat: 3205 / 816

Going ahead to step 6:
When dividing 3205 by 816, we get 3 with a remainder of 757.
Record the quotient 3 as the next digit in the result. 
Result so far: 1103.0
Subtract 2448 from 3205 to get 757.
Fetch the next digit (8) from the dividend, attach it to 757 and continue: 7578 / 816

Moving on to step 7:
816 can be fit into 7578 9 times, resulting in a remainder of 234.
The next digit of our result is 9. 
Result so far: 11039.0
The remainder is 234 after subtracting 7344 from 7578.
Take the next digit (1) from the dividend and append it to 234, then repeat: 2341 / 816

Moving on to step 8:
816 goes into 2341 2 times with a remainder of 709.
Write down 2 as next digit of the result. 
Result so far: 110392.0
The remainder is 709 after subtracting 1632 from 2341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

On to step 9:
816 goes into 7090 8 times with a remainder of 562.
Write down 8 as next digit of the result. 
Result so far: 110392.8
If we subtract 6528 from 7090, we get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Moving on to step 10:
If we divide 5620 by 816, we get 6 and a remainder of 724.
Put 6 as the next digit of the answer. 
Result so far: 110392.86
The remainder is 724 after subtracting 4896 from 5620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Moving on to step 11:
816 can be fit into 7240 8 times, resulting in a remainder of 712.
Record the quotient 8 as the next digit in the result. 
Result so far: 110392.868
Subtracting 6528 from 7240 leaves us with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Going ahead to step 12:
816 can be fit into 7120 8 times, resulting in a remainder of 592.
Record the quotient 8 as the next digit in the result. 
Result so far: 110392.8688
Subtract 6528 from 7120 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

The final result is 110392.8688 with a remainder of 0.00592.
