We divide 77710 by 90
We want to divide 77710 by 90.

Let's proceed to step 1:
The number 90 fits into 7 0 times, leaving 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.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 90

Advancing to step 2:
The number 90 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 90

Going ahead to step 3:
90 goes into 777 8 times with a remainder of 57.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 720 away from 777, we end up with 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 90

Going ahead to step 4:
When dividing 571 by 90, we get 6 with a remainder of 31.
The next digit of our result is 6. 
Result so far: 86.0
Subtracting 540 from 571 leaves us with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 90

Advancing to step 5:
90 goes into 310 3 times with a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 863.0
Subtracting 270 from 310 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.

Advancing to step 6:
90 goes into 400 4 times with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 863.4
If we subtract 360 from 400, we 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.

Moving on to step 7:
When dividing 400 by 90, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 863.44
Deduct 360 from 400 and we're left 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.

The final outcome is 863.44, with a leftover of 0.04.
