Let's divide 651235 by 90
Our goal is to divide 651235 by 90.

Moving on to step 1:
90 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 90

On to step 2:
90 can be fit into 65 0 times, resulting in a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 90

Moving on to step 3:
The number 90 fits into 651 7 times, leaving a remainder of 21.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 630 from 651, we get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 90

Step 4:
The number 90 fits into 212 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Deduct 180 from 212 and we're left with 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 90

Let's proceed to step 5:
The number 90 fits into 323 3 times, leaving a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 723.0
If we take 270 away from 323, we end up with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 90

Let's proceed to step 6:
If we divide 535 by 90, we get 5 and a remainder of 85.
The next digit of our result is 5. 
Result so far: 7235.0
Deduct 450 from 535 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 7:
850 divided by 90 is 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 7235.9
Subtracting 810 from 850 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
When dividing 400 by 90, we get 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 7235.94
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
400 divided by 90 is 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 7235.944
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 7235.944, and the remainder is 0.004.
