651480 ÷ 90 
We're looking to find how many times 90 goes into 651480.

Step 1:
90 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 90

Moving on to step 2:
When dividing 65 by 90, we get 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 90

Step 3:
The number 90 fits into 651 7 times, leaving a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 630 from 651, we get 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 90

Going ahead to step 4:
When dividing 214 by 90, we get 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 72.0
If we take 180 away from 214, we end up with 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 90

On to step 5:
348 divided by 90 is 3 with a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 723.0
Subtract 270 from 348 to get 78.
Include the next digit (0) from the dividend after 78, then repeat: 780 / 90

Advancing to step 6:
90 goes into 780 8 times with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 7238.0
Subtracting 720 from 780 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.

Going ahead to step 7:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 7238.6
Subtract 540 from 600 to get 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.
Write down 6 as next digit of the result. 
Result so far: 7238.66
Subtracting 540 from 600 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.

The final result is 7238.66 with a remainder of 0.06.
