171148 divided by 90 
We want to figure out the number of times 171148 can be divided by 90.

Let's proceed to step 1:
1 divided by 90 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 90

Let's proceed to step 2:
If we divide 17 by 90, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 90

Going ahead to step 3:
90 can be fit into 171 1 times, resulting in a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 81 after subtracting 90 from 171.
Append the next digit (1) from the dividend to 81 and continue with: 811 / 90

Moving on to step 4:
811 divided by 90 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 810 away from 811, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 90

On to step 5:
If we divide 14 by 90, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 90

Let's proceed to step 6:
148 divided by 90 is 1 with a remainder of 58.
The next digit of our result is 1. 
Result so far: 1901.0
Deduct 90 from 148 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 7:
90 can be fit into 580 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 1901.6
If we subtract 540 from 580, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 1901.64
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 1901.644
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 1901.644 with a balance of 0.004.
