We look at the division of 160258 by 90 
We're looking to find how many times 90 goes into 160258.

Let's proceed to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 90

Advancing to step 2:
When dividing 16 by 90, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 90

Moving on to step 3:
90 can be fit into 160 1 times, resulting in a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 90 from 160 leaves us with 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 90

Let's proceed to step 4:
If we divide 702 by 90, we get 7 and a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 630 from 702 leaves us with 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 90

Step 5:
90 goes into 725 8 times with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 178.0
The remainder is 5 after subtracting 720 from 725.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 90

On to step 6:
58 divided by 90 is 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 1780.0
Subtracting 0 from 58 leaves us 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:
If we divide 580 by 90, we get 6 and a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 1780.6
If we take 540 away from 580, we end up 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.

Moving on to step 8:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 1780.64
If we take 360 away from 400, we end up 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:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 1780.644
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 1780.644 with a remainder of 0.004.
