10404866 ÷ 526 
We want to divide 10404866 by 526.

On to step 1:
1 divided by 526 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 526

Let's proceed to step 2:
526 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 526

Let's proceed to step 3:
526 goes into 104 0 times with a remainder of 104.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 104 leaves us with 104.
Bring next digit (0) of the dividend behind the 104 and repeat the process: 1040 / 526

Step 4:
526 goes into 1040 1 times with a remainder of 514.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 526 from 1040 and we're left with 514.
Include the next digit (4) from the dividend after 514, then repeat: 5144 / 526

Step 5:
The number 526 fits into 5144 9 times, leaving a remainder of 410.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 4734 from 5144 leaves us with 410.
Fetch the next digit (8) from the dividend, attach it to 410 and continue: 4108 / 526

Step 6:
The number 526 fits into 4108 7 times, leaving a remainder of 426.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
Deduct 3682 from 4108 and we're left with 426.
Grab the next digit (6) from the dividend, add it to 426, then carry on: 4266 / 526

Advancing to step 7:
4266 divided by 526 is 8 with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 1978.0
If we subtract 4208 from 4266, we get 58.
Take the next digit (6) from the dividend and append it to 58, then repeat: 586 / 526

Let's proceed to step 8:
526 can be fit into 586 1 times, resulting in a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 19781.0
The remainder is 60 after subtracting 526 from 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
526 can be fit into 600 1 times, resulting in a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 19781.1
Subtract 526 from 600 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
When dividing 740 by 526, we get 1 with a remainder of 214.
The next digit of our result is 1. 
Result so far: 19781.11
Subtract 526 from 740 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Our division results in 19781.11 with a remaining 0.214.
