Let's divide 66140685 by 506
We're looking to find how many times 506 goes into 66140685.

On to step 1:
506 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.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 506

Let's proceed to step 2:
When dividing 66 by 506, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 506

Let's proceed to step 3:
If we divide 661 by 506, we get 1 and a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 506 away from 661, we end up with 155.
Include the next digit (4) from the dividend after 155, then repeat: 1554 / 506

Moving on to step 4:
If we divide 1554 by 506, we get 3 and a remainder of 36.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1518 from 1554, we get 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 506

Moving on to step 5:
When dividing 360 by 506, we get 0 with a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 130.0
Subtracting 0 from 360 leaves us with 360.
Bring next digit (6) of the dividend behind the 360 and repeat the process: 3606 / 506

On to step 6:
506 can be fit into 3606 7 times, resulting in a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 1307.0
Subtract 3542 from 3606 to get 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 506

Let's proceed to step 7:
648 divided by 506 is 1 with a remainder of 142.
Record the quotient 1 as the next digit in the result. 
Result so far: 13071.0
If we subtract 506 from 648, we get 142.
Grab the next digit (5) from the dividend, add it to 142, then carry on: 1425 / 506

Let's proceed to step 8:
506 goes into 1425 2 times with a remainder of 413.
The next digit of our result is 2. 
Result so far: 130712.0
Deduct 1012 from 1425 and we're left with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

On to step 9:
506 goes into 4130 8 times with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 130712.8
Deduct 4048 from 4130 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 10:
The number 506 fits into 820 1 times, leaving a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 130712.81
The remainder is 314 after subtracting 506 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 11:
506 goes into 3140 6 times with a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 130712.816
Subtract 3036 from 3140 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 12:
506 goes into 1040 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 130712.8162
If we subtract 1012 from 1040, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
If we divide 280 by 506, we get 0 and a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 130712.8162
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 14:
2800 divided by 506 is 5 with a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 130712.816205
If we subtract 2530 from 2800, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 15:
If we divide 2700 by 506, we get 5 and a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 130712.8162055
Deduct 2530 from 2700 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 130712.8162055, with a leftover of 1.7e-06.
