Let's divide 800258 by 77
Let's see how many times 77 fits into 800258.

On to step 1:
77 can be fit into 8 0 times, resulting in 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.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 77

Let's proceed to step 2:
77 goes into 80 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 77 away from 80, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 77

Step 3:
30 divided by 77 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 77

Step 4:
302 divided by 77 is 3 with a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 103.0
If we subtract 231 from 302, we get 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 77

Moving on to step 5:
77 can be fit into 715 9 times, resulting in a remainder of 22.
The next digit of our result is 9. 
Result so far: 1039.0
Deduct 693 from 715 and we're left with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 77

Going ahead to step 6:
77 goes into 228 2 times with a remainder of 74.
The next digit of our result is 2. 
Result so far: 10392.0
If we subtract 154 from 228, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 7:
The number 77 fits into 740 9 times, leaving a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 10392.9
If we take 693 away from 740, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 8:
The number 77 fits into 470 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 10392.96
The remainder is 8 after subtracting 462 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 77 fits into 80 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 10392.961
If we take 77 away from 80, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
If we divide 30 by 77, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 10392.961
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
When dividing 300 by 77, we get 3 with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 10392.96103
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 12:
If we divide 690 by 77, we get 8 and a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 10392.961038
Deduct 616 from 690 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 13:
The number 77 fits into 740 9 times, leaving a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 10392.9610389
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 14:
When dividing 470 by 77, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10392.96103896
If we take 462 away from 470, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 10392.96103896 with a remainder of 8e-09.
