43426 divided by 15 
We want to divide 43426 by 15.

Step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 15

Moving on to step 2:
When dividing 43 by 15, we get 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 30 from 43, we get 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 15

Let's proceed to step 3:
The number 15 fits into 134 8 times, leaving a remainder of 14.
The next digit of our result is 8. 
Result so far: 28.0
The remainder is 14 after subtracting 120 from 134.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 15

On to step 4:
The number 15 fits into 142 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 289.0
Deduct 135 from 142 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 15

Going ahead to step 5:
15 goes into 76 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 2895.0
If we subtract 75 from 76, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 6:
When dividing 10 by 15, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2895.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
When dividing 100 by 15, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 2895.06
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 2895.066
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 2895.066 with a remaining 0.001.
