134791 ÷ 90 
We're looking to find how many times 90 goes into 134791.

Going ahead to step 1:
1 divided by 90 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 90

Let's proceed to step 2:
90 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 90

Let's proceed to step 3:
If we divide 134 by 90, we get 1 and a remainder of 44.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 90 from 134 and we're left with 44.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 90

Step 4:
90 can be fit into 447 4 times, resulting in a remainder of 87.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 360 away from 447, we end up with 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 90

Moving on to step 5:
If we divide 879 by 90, we get 9 and a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 149.0
If we subtract 810 from 879, we get 69.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 90

Step 6:
When dividing 691 by 90, we get 7 with a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 1497.0
If we subtract 630 from 691, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
The number 90 fits into 610 6 times, leaving a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 1497.6
The remainder is 70 after subtracting 540 from 610.
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:
90 goes into 700 7 times with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 1497.67
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
If we divide 700 by 90, we get 7 and a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 1497.677
If we take 630 away from 700, 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.

After the division, we end up with 1497.677 and a remainder of 0.007.
