We look at the division of 70076399 by 816 
Let's see how many times 816 fits into 70076399.

Moving on to step 1:
If we divide 7 by 816, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 816

Step 2:
The number 816 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 816

Let's proceed to step 3:
The number 816 fits into 700 0 times, leaving a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 700, we end up with 700.
Append the next digit (7) from the dividend to 700 and continue with: 7007 / 816

Advancing to step 4:
The number 816 fits into 7007 8 times, leaving a remainder of 479.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 6528 from 7007 and we're left with 479.
Fetch the next digit (6) from the dividend, attach it to 479 and continue: 4796 / 816

Step 5:
The number 816 fits into 4796 5 times, leaving a remainder of 716.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
The remainder is 716 after subtracting 4080 from 4796.
Bring next digit (3) of the dividend behind the 716 and repeat the process: 7163 / 816

Let's proceed to step 6:
The number 816 fits into 7163 8 times, leaving a remainder of 635.
The number 8 becomes the next digit in our result. 
Result so far: 858.0
The remainder is 635 after subtracting 6528 from 7163.
Include the next digit (9) from the dividend after 635, then repeat: 6359 / 816

Step 7:
816 can be fit into 6359 7 times, resulting in a remainder of 647.
Record the quotient 7 as the next digit in the result. 
Result so far: 8587.0
The remainder is 647 after subtracting 5712 from 6359.
Append the next digit (9) from the dividend to 647 and continue with: 6479 / 816

Moving on to step 8:
816 goes into 6479 7 times with a remainder of 767.
The number 7 becomes the next digit in our result. 
Result so far: 85877.0
Deduct 5712 from 6479 and we're left with 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

Going ahead to step 9:
816 goes into 7670 9 times with a remainder of 326.
The next digit of our result is 9. 
Result so far: 85877.9
Deduct 7344 from 7670 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 10:
3260 divided by 816 is 3 with a remainder of 812.
Use 3 as the next digit of our solution. 
Result so far: 85877.93
Subtract 2448 from 3260 to get 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Let's proceed to step 11:
If we divide 8120 by 816, we get 9 and a remainder of 776.
Write down 9 as next digit of the result. 
Result so far: 85877.939
If we subtract 7344 from 8120, we get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Step 12:
816 goes into 7760 9 times with a remainder of 416.
The number 9 becomes the next digit in our result. 
Result so far: 85877.9399
Subtract 7344 from 7760 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

After the division, we end up with 85877.9399 and a remainder of 0.00416.
