77526340 ÷ 90 
Let's see how many times 90 fits into 77526340.

Moving on to step 1:
90 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 90

Step 2:
77 divided by 90 is 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 90

Step 3:
90 goes into 775 8 times with a remainder of 55.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 720 away from 775, we end up with 55.
Bring next digit (2) of the dividend behind the 55 and repeat the process: 552 / 90

On to step 4:
90 goes into 552 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 86.0
The remainder is 12 after subtracting 540 from 552.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 90

On to step 5:
If we divide 126 by 90, we get 1 and a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 861.0
The remainder is 36 after subtracting 90 from 126.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 90

Advancing to step 6:
The number 90 fits into 363 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 8614.0
If we take 360 away from 363, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 90

On to step 7:
When dividing 34 by 90, we get 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 86140.0
Deduct 0 from 34 and we're left with 34.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 90

Step 8:
If we divide 340 by 90, we get 3 and a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 861403.0
The remainder is 70 after subtracting 270 from 340.
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 9:
The number 90 fits into 700 7 times, leaving a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 861403.7
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.

Moving on to step 10:
When dividing 700 by 90, we get 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 861403.77
If we subtract 630 from 700, we 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.

In conclusion, the division gives 861403.77 with a balance of 0.07.
