Let's divide 168126 by 90
Let's see how many times 90 fits into 168126.

Step 1:
90 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 90

Advancing to step 2:
If we divide 16 by 90, we get 0 and a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 90

Advancing to step 3:
When dividing 168 by 90, we get 1 with a remainder of 78.
The next digit of our result is 1. 
Result so far: 1.0
If we take 90 away from 168, we end up with 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 90

Going ahead to step 4:
The number 90 fits into 781 8 times, leaving a remainder of 61.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 720 from 781 leaves us with 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 90

On to step 5:
When dividing 612 by 90, we get 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
If we take 540 away from 612, we end up with 72.
Grab the next digit (6) from the dividend, add it to 72, then carry on: 726 / 90

Let's proceed to step 6:
726 divided by 90 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 1868.0
If we take 720 away from 726, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
90 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 1868.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
The number 90 fits into 600 6 times, leaving a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 1868.06
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 1868.066
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 1868.066 with a balance of 0.006.
