We look at the division of 77545571 by 89 
We want to divide 77545571 by 89.

Going ahead to step 1:
When dividing 7 by 89, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 89

Step 2:
When dividing 77 by 89, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 89

Advancing to step 3:
When dividing 775 by 89, we get 8 with a remainder of 63.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 63 after subtracting 712 from 775.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 89

On to step 4:
89 can be fit into 634 7 times, resulting in a remainder of 11.
The next digit of our result is 7. 
Result so far: 87.0
Subtract 623 from 634 to get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 89

Going ahead to step 5:
89 can be fit into 115 1 times, resulting in a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 871.0
Deduct 89 from 115 and we're left with 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 89

Step 6:
If we divide 265 by 89, we get 2 and a remainder of 87.
Use 2 as the next digit of our solution. 
Result so far: 8712.0
The remainder is 87 after subtracting 178 from 265.
Grab the next digit (7) from the dividend, add it to 87, then carry on: 877 / 89

On to step 7:
If we divide 877 by 89, we get 9 and a remainder of 76.
Put 9 as the next digit of the answer. 
Result so far: 87129.0
Deduct 801 from 877 and we're left with 76.
Take the next digit (1) from the dividend and append it to 76, then repeat: 761 / 89

Step 8:
761 divided by 89 is 8 with a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 871298.0
If we subtract 712 from 761, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
490 divided by 89 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 871298.5
Deduct 445 from 490 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
When dividing 450 by 89, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 871298.55
If we subtract 445 from 450, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 871298.55, and the remainder is 0.005.
