We look at the division of 901438 by 10 
We want to divide 901438 by 10.

Step 1:
If we divide 9 by 10, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 10

Moving on to step 2:
90 divided by 10 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 90 from 90, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 10

Moving on to step 3:
When dividing 1 by 10, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 90.0
If we subtract 0 from 1, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 10

Step 4:
10 can be fit into 14 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 901.0
Subtracting 10 from 14 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 10

Moving on to step 5:
The number 10 fits into 43 4 times, leaving a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 9014.0
If we take 40 away from 43, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 10

Advancing to step 6:
When dividing 38 by 10, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 90143.0
The remainder is 8 after subtracting 30 from 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
80 divided by 10 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 90143.8
Subtracting 80 from 80 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 10 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 90143.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 90143.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 90143.8 with a remainder of 0.0.
