We're dividing 90151 by 10 
Our goal is to divide 90151 by 10.

Let's proceed to step 1:
When dividing 9 by 10, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 10

Moving on to step 2:
If we divide 90 by 10, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 90 away from 90, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 10

Going ahead to step 3:
1 divided by 10 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 90.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 10

Advancing to step 4:
The number 10 fits into 15 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 901.0
Subtract 10 from 15 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 10

Advancing to step 5:
When dividing 51 by 10, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 9015.0
Deduct 50 from 51 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
The number 10 fits into 10 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 9015.1
If we subtract 10 from 10, we 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.

Let's proceed to step 7:
0 divided by 10 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9015.1
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9015.1
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 outcome is 9015.1, with a leftover of 0.0.
