83686130 ÷ 820 
Let's see how many times 820 fits into 83686130.

Let's proceed to step 1:
8 divided by 820 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 820

Step 2:
When dividing 83 by 820, we get 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Append the next digit (6) from the dividend to 83 and continue with: 836 / 820

Let's proceed to step 3:
820 goes into 836 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 16 after subtracting 820 from 836.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 820

Step 4:
If we divide 168 by 820, we get 0 and a remainder of 168.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 168, we end up with 168.
Grab the next digit (6) from the dividend, add it to 168, then carry on: 1686 / 820

Let's proceed to step 5:
1686 divided by 820 is 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 102.0
Subtract 1640 from 1686 to get 46.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 820

Going ahead to step 6:
The number 820 fits into 461 0 times, leaving a remainder of 461.
Record the quotient 0 as the next digit in the result. 
Result so far: 1020.0
Subtracting 0 from 461 leaves us with 461.
Bring next digit (3) of the dividend behind the 461 and repeat the process: 4613 / 820

Going ahead to step 7:
820 can be fit into 4613 5 times, resulting in a remainder of 513.
Record the quotient 5 as the next digit in the result. 
Result so far: 10205.0
Subtracting 4100 from 4613 leaves us with 513.
Append the next digit (0) from the dividend to 513 and continue with: 5130 / 820

Moving on to step 8:
5130 divided by 820 is 6 with a remainder of 210.
Record the quotient 6 as the next digit in the result. 
Result so far: 102056.0
Subtract 4920 from 5130 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 9:
2100 divided by 820 is 2 with a remainder of 460.
The number 2 becomes the next digit in our result. 
Result so far: 102056.2
If we take 1640 away from 2100, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 10:
4600 divided by 820 is 5 with a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 102056.25
If we take 4100 away from 4600, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 11:
The number 820 fits into 5000 6 times, leaving a remainder of 80.
The next digit of our result is 6. 
Result so far: 102056.256
Deduct 4920 from 5000 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
800 divided by 820 is 0 with a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 102056.256
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 13:
820 goes into 8000 9 times with a remainder of 620.
Record the quotient 9 as the next digit in the result. 
Result so far: 102056.25609
The remainder is 620 after subtracting 7380 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 14:
The number 820 fits into 6200 7 times, leaving a remainder of 460.
Record the quotient 7 as the next digit in the result. 
Result so far: 102056.256097
If we take 5740 away from 6200, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 15:
The number 820 fits into 4600 5 times, leaving a remainder of 500.
Put 5 as the next digit of the answer. 
Result so far: 102056.2560975
The remainder is 500 after subtracting 4100 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 16:
5000 divided by 820 is 6 with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 102056.25609756
If we subtract 4920 from 5000, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 102056.25609756, and the remainder is 8e-08.
