We look at the division of 30640899 by 816 
We want to divide 30640899 by 816.

Advancing to step 1:
816 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 816

On to step 2:
816 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 816

Let's proceed to step 3:
The number 816 fits into 306 0 times, leaving a remainder of 306.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 306, we get 306.
Grab the next digit (4) from the dividend, add it to 306, then carry on: 3064 / 816

Moving on to step 4:
816 goes into 3064 3 times with a remainder of 616.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2448 from 3064 and we're left with 616.
Append the next digit (0) from the dividend to 616 and continue with: 6160 / 816

Step 5:
816 can be fit into 6160 7 times, resulting in a remainder of 448.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 5712 from 6160 and we're left with 448.
Fetch the next digit (8) from the dividend, attach it to 448 and continue: 4488 / 816

On to step 6:
The number 816 fits into 4488 5 times, leaving a remainder of 408.
The number 5 becomes the next digit in our result. 
Result so far: 375.0
Subtracting 4080 from 4488 leaves us with 408.
Grab the next digit (9) from the dividend, add it to 408, then carry on: 4089 / 816

Step 7:
The number 816 fits into 4089 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 3755.0
The remainder is 9 after subtracting 4080 from 4089.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 816

Step 8:
816 goes into 99 0 times with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 37550.0
Subtracting 0 from 99 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 9:
816 can be fit into 990 1 times, resulting in a remainder of 174.
Put 1 as the next digit of the answer. 
Result so far: 37550.1
Deduct 816 from 990 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 10:
1740 divided by 816 is 2 with a remainder of 108.
The next digit of our result is 2. 
Result so far: 37550.12
The remainder is 108 after subtracting 1632 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 11:
If we divide 1080 by 816, we get 1 and a remainder of 264.
Record the quotient 1 as the next digit in the result. 
Result so far: 37550.121
Subtract 816 from 1080 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 12:
816 goes into 2640 3 times with a remainder of 192.
Write down 3 as next digit of the result. 
Result so far: 37550.1213
Deduct 2448 from 2640 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 13:
1920 divided by 816 is 2 with a remainder of 288.
Write down 2 as next digit of the result. 
Result so far: 37550.12132
Subtracting 1632 from 1920 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 14:
The number 816 fits into 2880 3 times, leaving a remainder of 432.
The next digit of our result is 3. 
Result so far: 37550.121323
If we subtract 2448 from 2880, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 15:
If we divide 4320 by 816, we get 5 and a remainder of 240.
Write down 5 as next digit of the result. 
Result so far: 37550.1213235
If we take 4080 away from 4320, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
The number 816 fits into 2400 2 times, leaving a remainder of 768.
The number 2 becomes the next digit in our result. 
Result so far: 37550.12132352
Subtract 1632 from 2400 to get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Our division results in 37550.12132352 with a remaining 7.68e-07.
