We're dividing 154601 by 90 
We're looking to find how many times 90 goes into 154601.

Step 1:
90 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 90

Moving on to step 2:
90 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 90

Moving on to step 3:
The number 90 fits into 154 1 times, leaving a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 90 from 154 and we're left with 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 90

On to step 4:
The number 90 fits into 646 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 630 from 646 leaves us with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 90

Moving on to step 5:
160 divided by 90 is 1 with a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 171.0
The remainder is 70 after subtracting 90 from 160.
Take the next digit (1) from the dividend and append it to 70, then repeat: 701 / 90

Going ahead to step 6:
701 divided by 90 is 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 1717.0
If we subtract 630 from 701, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
90 goes into 710 7 times with a remainder of 80.
The number 7 becomes the next digit in our result. 
Result so far: 1717.7
The remainder is 80 after subtracting 630 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 1717.78
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
90 goes into 800 8 times with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 1717.788
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 1717.788, and the remainder is 0.008.
