77757445 ÷ 809 
Let's see how many times 809 fits into 77757445.

Step 1:
The number 809 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
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 809

On to step 2:
If we divide 77 by 809, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (7) from the dividend, add it to 77, then carry on: 777 / 809

Moving on to step 3:
809 goes into 777 0 times with a remainder of 777.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 777 and we're left with 777.
Include the next digit (5) from the dividend after 777, then repeat: 7775 / 809

Advancing to step 4:
When dividing 7775 by 809, we get 9 with a remainder of 494.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 494 after subtracting 7281 from 7775.
Append the next digit (7) from the dividend to 494 and continue with: 4947 / 809

Moving on to step 5:
809 can be fit into 4947 6 times, resulting in a remainder of 93.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we subtract 4854 from 4947, we get 93.
Take the next digit (4) from the dividend and append it to 93, then repeat: 934 / 809

Moving on to step 6:
934 divided by 809 is 1 with a remainder of 125.
Use 1 as the next digit of our solution. 
Result so far: 961.0
Subtracting 809 from 934 leaves us with 125.
Fetch the next digit (4) from the dividend, attach it to 125 and continue: 1254 / 809

Going ahead to step 7:
If we divide 1254 by 809, we get 1 and a remainder of 445.
The number 1 becomes the next digit in our result. 
Result so far: 9611.0
Subtracting 809 from 1254 leaves us with 445.
Append the next digit (5) from the dividend to 445 and continue with: 4455 / 809

Let's proceed to step 8:
When dividing 4455 by 809, we get 5 with a remainder of 410.
Record the quotient 5 as the next digit in the result. 
Result so far: 96115.0
Deduct 4045 from 4455 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 9:
If we divide 4100 by 809, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 96115.5
Subtracting 4045 from 4100 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
809 goes into 550 0 times with a remainder of 550.
The next digit of our result is 0. 
Result so far: 96115.5
If we take 0 away from 550, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 11:
When dividing 5500 by 809, we get 6 with a remainder of 646.
Write down 6 as next digit of the result. 
Result so far: 96115.506
Subtracting 4854 from 5500 leaves us with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Advancing to step 12:
809 goes into 6460 7 times with a remainder of 797.
Write down 7 as next digit of the result. 
Result so far: 96115.5067
Deduct 5663 from 6460 and we're left with 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Advancing to step 13:
If we divide 7970 by 809, we get 9 and a remainder of 689.
Record the quotient 9 as the next digit in the result. 
Result so far: 96115.50679
If we take 7281 away from 7970, we end up with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Going ahead to step 14:
6890 divided by 809 is 8 with a remainder of 418.
Put 8 as the next digit of the answer. 
Result so far: 96115.506798
Deduct 6472 from 6890 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 15:
809 can be fit into 4180 5 times, resulting in a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 96115.5067985
Subtracting 4045 from 4180 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 16:
809 goes into 1350 1 times with a remainder of 541.
The next digit of our result is 1. 
Result so far: 96115.50679851
Subtract 809 from 1350 to get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

The quotient of the division is 96115.50679851, and the remainder is 5.41e-07.
