We divide 26410390 by 870
We want to figure out the number of times 26410390 can be divided by 870.

Step 1:
When dividing 2 by 870, 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.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 870

On to step 2:
The number 870 fits into 26 0 times, leaving a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 870

Going ahead to step 3:
870 goes into 264 0 times with a remainder of 264.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 264 after subtracting 0 from 264.
Grab the next digit (1) from the dividend, add it to 264, then carry on: 2641 / 870

On to step 4:
2641 divided by 870 is 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 2610 from 2641 leaves us with 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 870

Moving on to step 5:
310 divided by 870 is 0 with a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 310, we end up with 310.
Append the next digit (3) from the dividend to 310 and continue with: 3103 / 870

Moving on to step 6:
The number 870 fits into 3103 3 times, leaving a remainder of 493.
Put 3 as the next digit of the answer. 
Result so far: 303.0
If we take 2610 away from 3103, we end up with 493.
Fetch the next digit (9) from the dividend, attach it to 493 and continue: 4939 / 870

Advancing to step 7:
870 can be fit into 4939 5 times, resulting in a remainder of 589.
The number 5 becomes the next digit in our result. 
Result so far: 3035.0
If we subtract 4350 from 4939, we get 589.
Take the next digit (0) from the dividend and append it to 589, then repeat: 5890 / 870

Let's proceed to step 8:
When dividing 5890 by 870, we get 6 with a remainder of 670.
The number 6 becomes the next digit in our result. 
Result so far: 30356.0
Subtracting 5220 from 5890 leaves us with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 9:
6700 divided by 870 is 7 with a remainder of 610.
Put 7 as the next digit of the answer. 
Result so far: 30356.7
If we take 6090 away from 6700, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 10:
When dividing 6100 by 870, we get 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 30356.77
Subtracting 6090 from 6100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 30356.77, and the remainder is 0.01.
