Let's divide 14551007 by 90
We want to divide 14551007 by 90.

Going ahead to step 1:
90 can be fit into 1 0 times, resulting in 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.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 90

Step 2:
90 can be fit into 14 0 times, resulting in a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 90

Advancing to step 3:
90 goes into 145 1 times with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 90 from 145 leaves us with 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 90

Moving on to step 4:
When dividing 555 by 90, we get 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 15 after subtracting 540 from 555.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 90

Moving on to step 5:
If we divide 151 by 90, we get 1 and a remainder of 61.
The next digit of our result is 1. 
Result so far: 161.0
Subtract 90 from 151 to get 61.
Fetch the next digit (0) from the dividend, attach it to 61 and continue: 610 / 90

Going ahead to step 6:
90 can be fit into 610 6 times, resulting in a remainder of 70.
The next digit of our result is 6. 
Result so far: 1616.0
If we take 540 away from 610, we end up with 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 90

On to step 7:
If we divide 700 by 90, we get 7 and a remainder of 70.
The next digit of our result is 7. 
Result so far: 16167.0
The remainder is 70 after subtracting 630 from 700.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 90

Let's proceed to step 8:
707 divided by 90 is 7 with a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 161677.0
If we take 630 away from 707, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
90 goes into 770 8 times with a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 161677.8
Subtracting 720 from 770 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
500 divided by 90 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 161677.85
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
If we divide 500 by 90, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 161677.855
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 161677.855 and a remainder of 0.005.
