Let's divide 30581151 by 819
We want to divide 30581151 by 819.

Advancing to step 1:
819 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 819

Step 2:
819 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 819

Advancing to step 3:
305 divided by 819 is 0 with a remainder of 305.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 305 and we're left with 305.
Fetch the next digit (8) from the dividend, attach it to 305 and continue: 3058 / 819

Let's proceed to step 4:
When dividing 3058 by 819, we get 3 with a remainder of 601.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2457 from 3058, we get 601.
Bring next digit (1) of the dividend behind the 601 and repeat the process: 6011 / 819

Advancing to step 5:
6011 divided by 819 is 7 with a remainder of 278.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we take 5733 away from 6011, we end up with 278.
Append the next digit (1) from the dividend to 278 and continue with: 2781 / 819

On to step 6:
819 goes into 2781 3 times with a remainder of 324.
Write down 3 as next digit of the result. 
Result so far: 373.0
Subtracting 2457 from 2781 leaves us with 324.
Fetch the next digit (5) from the dividend, attach it to 324 and continue: 3245 / 819

Advancing to step 7:
The number 819 fits into 3245 3 times, leaving a remainder of 788.
Record the quotient 3 as the next digit in the result. 
Result so far: 3733.0
The remainder is 788 after subtracting 2457 from 3245.
Grab the next digit (1) from the dividend, add it to 788, then carry on: 7881 / 819

On to step 8:
7881 divided by 819 is 9 with a remainder of 510.
Put 9 as the next digit of the answer. 
Result so far: 37339.0
Subtracting 7371 from 7881 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 9:
5100 divided by 819 is 6 with a remainder of 186.
The number 6 becomes the next digit in our result. 
Result so far: 37339.6
Subtract 4914 from 5100 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 10:
1860 divided by 819 is 2 with a remainder of 222.
Put 2 as the next digit of the answer. 
Result so far: 37339.62
Deduct 1638 from 1860 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 11:
When dividing 2220 by 819, we get 2 with a remainder of 582.
The next digit of our result is 2. 
Result so far: 37339.622
Deduct 1638 from 2220 and we're left with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

The final outcome is 37339.622, with a leftover of 0.0582.
