30109105 divided by 821 
We're looking to find how many times 821 goes into 30109105.

Step 1:
3 divided by 821 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 821

Going ahead to step 2:
If we divide 30 by 821, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 821

Going ahead to step 3:
When dividing 301 by 821, we get 0 with a remainder of 301.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 301, we end up with 301.
Append the next digit (0) from the dividend to 301 and continue with: 3010 / 821

Step 4:
If we divide 3010 by 821, we get 3 and a remainder of 547.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 547 after subtracting 2463 from 3010.
Append the next digit (9) from the dividend to 547 and continue with: 5479 / 821

Moving on to step 5:
5479 divided by 821 is 6 with a remainder of 553.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Deduct 4926 from 5479 and we're left with 553.
Append the next digit (1) from the dividend to 553 and continue with: 5531 / 821

Let's proceed to step 6:
821 goes into 5531 6 times with a remainder of 605.
The next digit of our result is 6. 
Result so far: 366.0
The remainder is 605 after subtracting 4926 from 5531.
Append the next digit (0) from the dividend to 605 and continue with: 6050 / 821

Moving on to step 7:
821 can be fit into 6050 7 times, resulting in a remainder of 303.
The number 7 becomes the next digit in our result. 
Result so far: 3667.0
If we take 5747 away from 6050, we end up with 303.
Take the next digit (5) from the dividend and append it to 303, then repeat: 3035 / 821

Let's proceed to step 8:
If we divide 3035 by 821, we get 3 and a remainder of 572.
The number 3 becomes the next digit in our result. 
Result so far: 36673.0
Deduct 2463 from 3035 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

On to step 9:
5720 divided by 821 is 6 with a remainder of 794.
Record the quotient 6 as the next digit in the result. 
Result so far: 36673.6
Subtract 4926 from 5720 to get 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Going ahead to step 10:
When dividing 7940 by 821, we get 9 with a remainder of 551.
Write down 9 as next digit of the result. 
Result so far: 36673.69
The remainder is 551 after subtracting 7389 from 7940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Let's proceed to step 11:
If we divide 5510 by 821, we get 6 and a remainder of 584.
The number 6 becomes the next digit in our result. 
Result so far: 36673.696
If we take 4926 away from 5510, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 12:
If we divide 5840 by 821, we get 7 and a remainder of 93.
Record the quotient 7 as the next digit in the result. 
Result so far: 36673.6967
If we take 5747 away from 5840, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 13:
If we divide 930 by 821, we get 1 and a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 36673.69671
Subtract 821 from 930 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 14:
The number 821 fits into 1090 1 times, leaving a remainder of 269.
Write down 1 as next digit of the result. 
Result so far: 36673.696711
Subtract 821 from 1090 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

In conclusion, the division gives 36673.696711 with a balance of 2.69e-05.
