We look at the division of 711493 by 90 
We want to figure out the number of times 711493 can be divided by 90.

Moving on to step 1:
If we divide 7 by 90, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 90

On to step 2:
90 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 90

Going ahead to step 3:
If we divide 711 by 90, we get 7 and a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 630 from 711, we get 81.
Take the next digit (4) from the dividend and append it to 81, then repeat: 814 / 90

Let's proceed to step 4:
814 divided by 90 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Deduct 810 from 814 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 90

Advancing to step 5:
90 goes into 49 0 times with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 790.0
The remainder is 49 after subtracting 0 from 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 90

Going ahead to step 6:
493 divided by 90 is 5 with a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 7905.0
If we subtract 450 from 493, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
90 goes into 430 4 times with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 7905.4
Deduct 360 from 430 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.

Advancing to step 8:
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: 7905.47
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.

Let's proceed to step 9:
If we divide 700 by 90, we get 7 and a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 7905.477
Subtract 630 from 700 to get 70.
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 outcome is 7905.477, with a leftover of 0.007.
