We divide 149657 by 90
We want to figure out the number of times 149657 can be divided by 90.

On to step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 90

On to step 2:
If we divide 14 by 90, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 90

Advancing to step 3:
90 can be fit into 149 1 times, resulting in a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 90 from 149, we get 59.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 90

Going ahead to step 4:
When dividing 596 by 90, we get 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 540 from 596 leaves us with 56.
Include the next digit (5) from the dividend after 56, then repeat: 565 / 90

On to step 5:
The number 90 fits into 565 6 times, leaving a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 166.0
Deduct 540 from 565 and we're left with 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 90

Moving on to step 6:
The number 90 fits into 257 2 times, leaving a remainder of 77.
Use 2 as the next digit of our solution. 
Result so far: 1662.0
The remainder is 77 after subtracting 180 from 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
90 can be fit into 770 8 times, resulting in a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 1662.8
Subtracting 720 from 770 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
90 can be fit into 500 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1662.85
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
If we divide 500 by 90, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1662.855
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 1662.855 with a remaining 0.005.
