30085828 ÷ 820 
We want to figure out the number of times 30085828 can be divided by 820.

Going ahead to step 1:
If we divide 3 by 820, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 820

Advancing to step 2:
If we divide 30 by 820, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 820

On to step 3:
The number 820 fits into 300 0 times, leaving a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 300 after subtracting 0 from 300.
Append the next digit (8) from the dividend to 300 and continue with: 3008 / 820

Advancing to step 4:
The number 820 fits into 3008 3 times, leaving a remainder of 548.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2460 from 3008 and we're left with 548.
Include the next digit (5) from the dividend after 548, then repeat: 5485 / 820

Going ahead to step 5:
When dividing 5485 by 820, we get 6 with a remainder of 565.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtract 4920 from 5485 to get 565.
Append the next digit (8) from the dividend to 565 and continue with: 5658 / 820

On to step 6:
When dividing 5658 by 820, we get 6 with a remainder of 738.
The next digit of our result is 6. 
Result so far: 366.0
The remainder is 738 after subtracting 4920 from 5658.
Take the next digit (2) from the dividend and append it to 738, then repeat: 7382 / 820

Advancing to step 7:
When dividing 7382 by 820, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 3669.0
Subtracting 7380 from 7382 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 820

On to step 8:
28 divided by 820 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 36690.0
Deduct 0 from 28 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
280 divided by 820 is 0 with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 36690.0
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 10:
820 goes into 2800 3 times with a remainder of 340.
Use 3 as the next digit of our solution. 
Result so far: 36690.03
If we take 2460 away from 2800, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 11:
The number 820 fits into 3400 4 times, leaving a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 36690.034
If we subtract 3280 from 3400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
1200 divided by 820 is 1 with a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 36690.0341
The remainder is 380 after subtracting 820 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 13:
820 can be fit into 3800 4 times, resulting in a remainder of 520.
Use 4 as the next digit of our solution. 
Result so far: 36690.03414
Deduct 3280 from 3800 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 14:
5200 divided by 820 is 6 with a remainder of 280.
The next digit of our result is 6. 
Result so far: 36690.034146
If we subtract 4920 from 5200, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 15:
If we divide 2800 by 820, we get 3 and a remainder of 340.
The number 3 becomes the next digit in our result. 
Result so far: 36690.0341463
Deduct 2460 from 2800 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 16:
820 can be fit into 3400 4 times, resulting in a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 36690.03414634
Deduct 3280 from 3400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 36690.03414634 with a remaining 1.2e-07.
