Let's divide 30131084 by 821
We want to figure out the number of times 30131084 can be divided by 821.

Advancing to step 1:
If we divide 3 by 821, we get 0 and 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.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 821

On to step 2:
821 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 821

On to step 3:
821 goes into 301 0 times with a remainder of 301.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 301 and we're left with 301.
Append the next digit (3) from the dividend to 301 and continue with: 3013 / 821

Step 4:
The number 821 fits into 3013 3 times, leaving a remainder of 550.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2463 from 3013 to get 550.
Fetch the next digit (1) from the dividend, attach it to 550 and continue: 5501 / 821

On to step 5:
821 can be fit into 5501 6 times, resulting in a remainder of 575.
The next digit of our result is 6. 
Result so far: 36.0
If we take 4926 away from 5501, we end up with 575.
Bring next digit (0) of the dividend behind the 575 and repeat the process: 5750 / 821

Step 6:
If we divide 5750 by 821, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 367.0
Subtracting 5747 from 5750 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 821

Let's proceed to step 7:
821 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 3670.0
The remainder is 38 after subtracting 0 from 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 821

Advancing to step 8:
If we divide 384 by 821, we get 0 and a remainder of 384.
The next digit of our result is 0. 
Result so far: 36700.0
Deduct 0 from 384 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 9:
821 goes into 3840 4 times with a remainder of 556.
Record the quotient 4 as the next digit in the result. 
Result so far: 36700.4
Subtract 3284 from 3840 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Moving on to step 10:
When dividing 5560 by 821, we get 6 with a remainder of 634.
The next digit of our result is 6. 
Result so far: 36700.46
If we subtract 4926 from 5560, we get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Moving on to step 11:
6340 divided by 821 is 7 with a remainder of 593.
The number 7 becomes the next digit in our result. 
Result so far: 36700.467
If we subtract 5747 from 6340, we get 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Let's proceed to step 12:
When dividing 5930 by 821, we get 7 with a remainder of 183.
Write down 7 as next digit of the result. 
Result so far: 36700.4677
If we take 5747 away from 5930, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Our division results in 36700.4677 with a remaining 0.00183.
