26166807 ÷ 990 
We're looking to find how many times 990 goes into 26166807.

Moving on to step 1:
When dividing 2 by 990, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 990

Going ahead to step 2:
When dividing 26 by 990, we get 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 990

Going ahead to step 3:
When dividing 261 by 990, we get 0 with a remainder of 261.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 261 to get 261.
Bring next digit (6) of the dividend behind the 261 and repeat the process: 2616 / 990

Step 4:
990 goes into 2616 2 times with a remainder of 636.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1980 from 2616 to get 636.
Fetch the next digit (6) from the dividend, attach it to 636 and continue: 6366 / 990

Let's proceed to step 5:
When dividing 6366 by 990, we get 6 with a remainder of 426.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 426 after subtracting 5940 from 6366.
Grab the next digit (8) from the dividend, add it to 426, then carry on: 4268 / 990

Advancing to step 6:
The number 990 fits into 4268 4 times, leaving a remainder of 308.
The next digit of our result is 4. 
Result so far: 264.0
The remainder is 308 after subtracting 3960 from 4268.
Take the next digit (0) from the dividend and append it to 308, then repeat: 3080 / 990

Going ahead to step 7:
The number 990 fits into 3080 3 times, leaving a remainder of 110.
Write down 3 as next digit of the result. 
Result so far: 2643.0
Deduct 2970 from 3080 and we're left with 110.
Bring next digit (7) of the dividend behind the 110 and repeat the process: 1107 / 990

Advancing to step 8:
990 can be fit into 1107 1 times, resulting in a remainder of 117.
The next digit of our result is 1. 
Result so far: 26431.0
Deduct 990 from 1107 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 9:
When dividing 1170 by 990, we get 1 with a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 26431.1
If we take 990 away from 1170, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
990 can be fit into 1800 1 times, resulting in a remainder of 810.
The number 1 becomes the next digit in our result. 
Result so far: 26431.11
If we subtract 990 from 1800, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

The quotient of the division is 26431.11, and the remainder is 0.81.
