140958 ÷ 90 
Our goal is to divide 140958 by 90.

Advancing to 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
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 90

Going ahead to step 2:
90 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 90

On to step 3:
If we divide 140 by 90, we get 1 and a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 90 from 140 to get 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 90

Let's proceed to step 4:
If we divide 509 by 90, we get 5 and a remainder of 59.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 59 after subtracting 450 from 509.
Grab the next digit (5) from the dividend, add it to 59, then carry on: 595 / 90

On to step 5:
90 goes into 595 6 times with a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
The remainder is 55 after subtracting 540 from 595.
Fetch the next digit (8) from the dividend, attach it to 55 and continue: 558 / 90

Going ahead to step 6:
If we divide 558 by 90, we get 6 and a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 1566.0
Subtracting 540 from 558 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
The number 90 fits into 180 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 1566.2
Subtracting 180 from 180 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 90, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1566.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 90 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1566.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1566.2 and a remainder of 0.0.
