We look at the division of 903786 by 43 
Let's see how many times 43 fits into 903786.

On to step 1:
43 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 43

On to step 2:
The number 43 fits into 90 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 86 from 90 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 43

Going ahead to step 3:
43 goes into 43 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 43 away from 43, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 43

Moving on to step 4:
7 divided by 43 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 210.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 43

Let's proceed to step 5:
78 divided by 43 is 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 2101.0
The remainder is 35 after subtracting 43 from 78.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 43

On to step 6:
When dividing 356 by 43, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 21018.0
Subtracting 344 from 356 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
43 can be fit into 120 2 times, resulting in a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 21018.2
Subtract 86 from 120 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
When dividing 340 by 43, we get 7 with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 21018.27
If we subtract 301 from 340, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
43 goes into 390 9 times with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 21018.279
If we subtract 387 from 390, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
If we divide 30 by 43, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 21018.279
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
If we divide 300 by 43, we get 6 and a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 21018.27906
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
If we divide 420 by 43, we get 9 and a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 21018.279069
If we take 387 away from 420, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 13:
330 divided by 43 is 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 21018.2790697
If we subtract 301 from 330, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 14:
If we divide 290 by 43, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 21018.27906976
The remainder is 32 after subtracting 258 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 21018.27906976 with a remaining 3.2e-08.
