We're dividing 802564 by 77 
We want to figure out the number of times 802564 can be divided by 77.

Advancing to step 1:
The number 77 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 77

Going ahead to step 2:
When dividing 80 by 77, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 77 from 80 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 77

Going ahead to step 3:
77 goes into 32 0 times with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 32 leaves us with 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 77

On to step 4:
77 goes into 325 4 times with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Subtract 308 from 325 to get 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 77

Step 5:
77 can be fit into 176 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 1042.0
The remainder is 22 after subtracting 154 from 176.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 77

On to step 6:
When dividing 224 by 77, we get 2 with a remainder of 70.
The next digit of our result is 2. 
Result so far: 10422.0
Deduct 154 from 224 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.

Let's proceed to step 7:
77 can be fit into 700 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 10422.9
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
77 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 10422.9
If we take 0 away from 70, we end up 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.

Step 9:
When dividing 700 by 77, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 10422.909
Subtracting 693 from 700 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
If we divide 70 by 77, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 10422.909
The remainder is 70 after subtracting 0 from 70.
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 11:
77 goes into 700 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 10422.90909
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
77 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 10422.90909
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
700 divided by 77 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 10422.9090909
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
70 divided by 77 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 10422.9090909
Subtracting 0 from 70 leaves us 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.

The final outcome is 10422.9090909, with a leftover of 7e-08.
