We're dividing 93123 by 90 
Let's see how many times 90 fits into 93123.

Advancing to step 1:
If we divide 9 by 90, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 90

On to step 2:
90 goes into 93 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 90 from 93, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 90

Let's proceed to step 3:
The number 90 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 31, we get 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 90

On to step 4:
The number 90 fits into 312 3 times, leaving a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
The remainder is 42 after subtracting 270 from 312.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 90

Advancing to step 5:
90 can be fit into 423 4 times, resulting in a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 1034.0
Subtract 360 from 423 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 6:
If we divide 630 by 90, we get 7 and a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 1034.7
Deduct 630 from 630 and we're left 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.

Moving on to step 7:
If we divide 0 by 90, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1034.7
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.

On to step 8:
When dividing 0 by 90, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1034.7
The remainder is 0 after subtracting 0 from 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 1034.7 and a remainder of 0.0.
