We divide 16305103 by 90
We want to divide 16305103 by 90.

Moving on to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 90

Let's proceed to step 2:
If we divide 16 by 90, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 90

Let's proceed to step 3:
If we divide 163 by 90, we get 1 and a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 73 after subtracting 90 from 163.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 90

On to step 4:
If we divide 730 by 90, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 10 after subtracting 720 from 730.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 90

Let's proceed to step 5:
If we divide 105 by 90, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 181.0
The remainder is 15 after subtracting 90 from 105.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 90

On to step 6:
90 can be fit into 151 1 times, resulting in a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 1811.0
If we take 90 away from 151, we end up with 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 90

On to step 7:
610 divided by 90 is 6 with a remainder of 70.
The next digit of our result is 6. 
Result so far: 18116.0
If we subtract 540 from 610, we get 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 90

On to step 8:
703 divided by 90 is 7 with a remainder of 73.
The next digit of our result is 7. 
Result so far: 181167.0
If we take 630 away from 703, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 9:
90 can be fit into 730 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 181167.8
If we subtract 720 from 730, 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.

Let's proceed to step 10:
90 goes into 100 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 181167.81
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.

On to step 11:
When dividing 100 by 90, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 181167.811
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 181167.811 and a remainder of 0.001.
