We look at the division of 150319 by 90 
We're looking to find how many times 90 goes into 150319.

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
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 90

Let's proceed to step 2:
The number 90 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 90

Moving on to step 3:
If we divide 150 by 90, we get 1 and a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 90 from 150 to get 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 90

Moving on to step 4:
90 goes into 603 6 times with a remainder of 63.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 63 after subtracting 540 from 603.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 90

Step 5:
If we divide 631 by 90, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
If we take 630 away from 631, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 90

Advancing to step 6:
The number 90 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 1670.0
If we subtract 0 from 19, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
The number 90 fits into 190 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 1670.2
Subtract 180 from 190 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 90, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1670.21
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
90 goes into 100 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1670.211
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 1670.211, and the remainder is 0.001.
