We divide 141649 by 90
Let's see how many times 90 fits into 141649.

Step 1:
The number 90 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 90

Advancing to step 2:
90 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 90

Step 3:
90 can be fit into 141 1 times, resulting in a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 51 after subtracting 90 from 141.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 90

Let's proceed to step 4:
When dividing 516 by 90, we get 5 with a remainder of 66.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 450 from 516, we get 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 90

Advancing to step 5:
90 can be fit into 664 7 times, resulting in a remainder of 34.
The next digit of our result is 7. 
Result so far: 157.0
If we take 630 away from 664, we end up with 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 90

Going ahead to step 6:
349 divided by 90 is 3 with a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 1573.0
Subtracting 270 from 349 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 7:
790 divided by 90 is 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 1573.8
If we take 720 away from 790, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
700 divided by 90 is 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 1573.87
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 1573.877
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 1573.877, with a leftover of 0.007.
