Let's divide 66087201 by 820
Our goal is to divide 66087201 by 820.

Moving on to step 1:
820 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 820

Step 2:
If we divide 66 by 820, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 820

Going ahead to step 3:
If we divide 660 by 820, we get 0 and a remainder of 660.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 660 and we're left with 660.
Fetch the next digit (8) from the dividend, attach it to 660 and continue: 6608 / 820

Going ahead to step 4:
When dividing 6608 by 820, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 6560 from 6608, we get 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 820

Moving on to step 5:
When dividing 487 by 820, we get 0 with a remainder of 487.
The next digit of our result is 0. 
Result so far: 80.0
If we take 0 away from 487, we end up with 487.
Fetch the next digit (2) from the dividend, attach it to 487 and continue: 4872 / 820

Moving on to step 6:
If we divide 4872 by 820, we get 5 and a remainder of 772.
The number 5 becomes the next digit in our result. 
Result so far: 805.0
If we take 4100 away from 4872, we end up with 772.
Take the next digit (0) from the dividend and append it to 772, then repeat: 7720 / 820

Moving on to step 7:
The number 820 fits into 7720 9 times, leaving a remainder of 340.
Write down 9 as next digit of the result. 
Result so far: 8059.0
If we subtract 7380 from 7720, we get 340.
Fetch the next digit (1) from the dividend, attach it to 340 and continue: 3401 / 820

Let's proceed to step 8:
The number 820 fits into 3401 4 times, leaving a remainder of 121.
The number 4 becomes the next digit in our result. 
Result so far: 80594.0
If we take 3280 away from 3401, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 9:
The number 820 fits into 1210 1 times, leaving a remainder of 390.
Record the quotient 1 as the next digit in the result. 
Result so far: 80594.1
If we subtract 820 from 1210, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 10:
3900 divided by 820 is 4 with a remainder of 620.
The number 4 becomes the next digit in our result. 
Result so far: 80594.14
If we subtract 3280 from 3900, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 11:
If we divide 6200 by 820, we get 7 and a remainder of 460.
Record the quotient 7 as the next digit in the result. 
Result so far: 80594.147
The remainder is 460 after subtracting 5740 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 12:
If we divide 4600 by 820, we get 5 and a remainder of 500.
The next digit of our result is 5. 
Result so far: 80594.1475
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.

Going ahead to step 13:
If we divide 5000 by 820, we get 6 and a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 80594.14756
The remainder is 80 after subtracting 4920 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 14:
When dividing 800 by 820, we get 0 with a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 80594.14756
Subtract 0 from 800 to 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.

Advancing to step 15:
The number 820 fits into 8000 9 times, leaving a remainder of 620.
The next digit of our result is 9. 
Result so far: 80594.1475609
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.

On to step 16:
The number 820 fits into 6200 7 times, leaving a remainder of 460.
The next digit of our result is 7. 
Result so far: 80594.14756097
If we subtract 5740 from 6200, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The quotient of the division is 80594.14756097, and the remainder is 4.6e-07.
