We're dividing 66060534 by 820 
We want to divide 66060534 by 820.

Step 1:
820 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 820

Moving on to step 2:
820 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 820

On to step 3:
When dividing 660 by 820, we get 0 with a remainder of 660.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 660 leaves us with 660.
Append the next digit (6) from the dividend to 660 and continue with: 6606 / 820

On to step 4:
If we divide 6606 by 820, we get 8 and a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 6560 from 6606 leaves us with 46.
Take the next digit (0) from the dividend and append it to 46, then repeat: 460 / 820

Let's proceed to step 5:
820 goes into 460 0 times with a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 80.0
Deduct 0 from 460 and we're left with 460.
Append the next digit (5) from the dividend to 460 and continue with: 4605 / 820

Let's proceed to step 6:
820 goes into 4605 5 times with a remainder of 505.
Use 5 as the next digit of our solution. 
Result so far: 805.0
If we subtract 4100 from 4605, we get 505.
Bring next digit (3) of the dividend behind the 505 and repeat the process: 5053 / 820

Step 7:
The number 820 fits into 5053 6 times, leaving a remainder of 133.
Put 6 as the next digit of the answer. 
Result so far: 8056.0
Subtracting 4920 from 5053 leaves us with 133.
Append the next digit (4) from the dividend to 133 and continue with: 1334 / 820

On to step 8:
820 goes into 1334 1 times with a remainder of 514.
Record the quotient 1 as the next digit in the result. 
Result so far: 80561.0
Deduct 820 from 1334 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Moving on to step 9:
The number 820 fits into 5140 6 times, leaving a remainder of 220.
Record the quotient 6 as the next digit in the result. 
Result so far: 80561.6
Subtract 4920 from 5140 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 10:
When dividing 2200 by 820, we get 2 with a remainder of 560.
Use 2 as the next digit of our solution. 
Result so far: 80561.62
Deduct 1640 from 2200 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 11:
5600 divided by 820 is 6 with a remainder of 680.
Write down 6 as next digit of the result. 
Result so far: 80561.626
The remainder is 680 after subtracting 4920 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

On to step 12:
820 goes into 6800 8 times with a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 80561.6268
Subtracting 6560 from 6800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
820 can be fit into 2400 2 times, resulting in a remainder of 760.
Write down 2 as next digit of the result. 
Result so far: 80561.62682
Subtracting 1640 from 2400 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 14:
When dividing 7600 by 820, we get 9 with a remainder of 220.
Write down 9 as next digit of the result. 
Result so far: 80561.626829
The remainder is 220 after subtracting 7380 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 15:
If we divide 2200 by 820, we get 2 and a remainder of 560.
Use 2 as the next digit of our solution. 
Result so far: 80561.6268292
Deduct 1640 from 2200 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 16:
If we divide 5600 by 820, we get 6 and a remainder of 680.
Use 6 as the next digit of our solution. 
Result so far: 80561.62682926
Subtract 4920 from 5600 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

The final outcome is 80561.62682926, with a leftover of 6.8e-07.
