We're dividing 10660807 by 525 
We want to figure out the number of times 10660807 can be divided by 525.

Going ahead to step 1:
525 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 525

Moving on to step 2:
525 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 525

On to step 3:
When dividing 106 by 525, we get 0 with a remainder of 106.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 106 and we're left with 106.
Include the next digit (6) from the dividend after 106, then repeat: 1066 / 525

On to step 4:
The number 525 fits into 1066 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1050 from 1066 to get 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 525

Step 5:
When dividing 160 by 525, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 160 and we're left with 160.
Take the next digit (8) from the dividend and append it to 160, then repeat: 1608 / 525

Advancing to step 6:
1608 divided by 525 is 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
Deduct 1575 from 1608 and we're left with 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 525

Step 7:
525 can be fit into 330 0 times, resulting in a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 2030.0
If we take 0 away from 330, we end up with 330.
Append the next digit (7) from the dividend to 330 and continue with: 3307 / 525

Advancing to step 8:
525 can be fit into 3307 6 times, resulting in a remainder of 157.
The number 6 becomes the next digit in our result. 
Result so far: 20306.0
If we take 3150 away from 3307, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 9:
525 can be fit into 1570 2 times, resulting in a remainder of 520.
The number 2 becomes the next digit in our result. 
Result so far: 20306.2
If we take 1050 away from 1570, we end up 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.

Advancing to step 10:
5200 divided by 525 is 9 with a remainder of 475.
Use 9 as the next digit of our solution. 
Result so far: 20306.29
If we subtract 4725 from 5200, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 11:
The number 525 fits into 4750 9 times, leaving a remainder of 25.
The next digit of our result is 9. 
Result so far: 20306.299
Subtract 4725 from 4750 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 20306.299, with a leftover of 0.0025.
