We divide 722437 by 90
Let's see how many times 90 fits into 722437.

Let's proceed to step 1:
90 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 90

Advancing to step 2:
If we divide 72 by 90, we get 0 and a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 90

Going ahead to step 3:
722 divided by 90 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 720 from 722, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 90

Moving on to step 4:
90 can be fit into 24 0 times, resulting in a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtracting 0 from 24 leaves us with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 90

Advancing to step 5:
90 can be fit into 243 2 times, resulting in a remainder of 63.
Put 2 as the next digit of the answer. 
Result so far: 802.0
The remainder is 63 after subtracting 180 from 243.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 90

On to step 6:
90 goes into 637 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 8027.0
Subtracting 630 from 637 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 90 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 8027.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
If we divide 700 by 90, we get 7 and a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 8027.07
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
700 divided by 90 is 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 8027.077
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 8027.077 with a remainder of 0.007.
