We look at the division of 26433594 by 870 
Let's see how many times 870 fits into 26433594.

Moving on to step 1:
When dividing 2 by 870, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 870

Step 2:
The number 870 fits into 26 0 times, leaving a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 870

Advancing to step 3:
The number 870 fits into 264 0 times, leaving a remainder of 264.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 264 after subtracting 0 from 264.
Grab the next digit (3) from the dividend, add it to 264, then carry on: 2643 / 870

Moving on to step 4:
2643 divided by 870 is 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 2610 away from 2643, we end up with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 870

Advancing to step 5:
If we divide 333 by 870, we get 0 and a remainder of 333.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 333 and we're left with 333.
Grab the next digit (5) from the dividend, add it to 333, then carry on: 3335 / 870

Moving on to step 6:
If we divide 3335 by 870, we get 3 and a remainder of 725.
Use 3 as the next digit of our solution. 
Result so far: 303.0
The remainder is 725 after subtracting 2610 from 3335.
Bring next digit (9) of the dividend behind the 725 and repeat the process: 7259 / 870

On to step 7:
7259 divided by 870 is 8 with a remainder of 299.
Put 8 as the next digit of the answer. 
Result so far: 3038.0
If we subtract 6960 from 7259, we get 299.
Append the next digit (4) from the dividend to 299 and continue with: 2994 / 870

Going ahead to step 8:
When dividing 2994 by 870, we get 3 with a remainder of 384.
Use 3 as the next digit of our solution. 
Result so far: 30383.0
Deduct 2610 from 2994 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 9:
870 goes into 3840 4 times with a remainder of 360.
Put 4 as the next digit of the answer. 
Result so far: 30383.4
Subtracting 3480 from 3840 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 10:
If we divide 3600 by 870, we get 4 and a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 30383.44
Subtract 3480 from 3600 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 30383.44 with a remainder of 0.12.
