192126 ÷ 90 
Let's see how many times 90 fits into 192126.

Advancing to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 90

Step 2:
90 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 90

Moving on to step 3:
90 can be fit into 192 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 180 from 192 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 90

Going ahead to step 4:
The number 90 fits into 121 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 90 from 121 and we're left with 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 90

On to step 5:
90 can be fit into 312 3 times, resulting in a remainder of 42.
The next digit of our result is 3. 
Result so far: 213.0
The remainder is 42 after subtracting 270 from 312.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 90

Moving on to step 6:
The number 90 fits into 426 4 times, leaving a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 2134.0
Deduct 360 from 426 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
When dividing 660 by 90, we get 7 with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 2134.7
Deduct 630 from 660 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 90 fits into 300 3 times, leaving a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 2134.73
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
When dividing 300 by 90, we get 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 2134.733
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 2134.733 and a remainder of 0.003.
