We're dividing 770843 by 77 
We want to divide 770843 by 77.

Advancing to step 1:
If we divide 7 by 77, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 77

Moving on to step 2:
77 can be fit into 77 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 77 from 77 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 77

On to step 3:
77 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 77

Going ahead to step 4:
8 divided by 77 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 77

Advancing to step 5:
If we divide 84 by 77, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1001.0
Deduct 77 from 84 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 77

Going ahead to step 6:
When dividing 73 by 77, we get 0 with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 10010.0
If we take 0 away from 73, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
When dividing 730 by 77, we get 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 10010.9
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
77 can be fit into 370 4 times, resulting in a remainder of 62.
The next digit of our result is 4. 
Result so far: 10010.94
Deduct 308 from 370 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
620 divided by 77 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 10010.948
If we take 616 away from 620, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
If we divide 40 by 77, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10010.948
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
If we divide 400 by 77, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 10010.94805
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
77 can be fit into 150 1 times, resulting in a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 10010.948051
If we subtract 77 from 150, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 13:
77 can be fit into 730 9 times, resulting in a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 10010.9480519
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 14:
The number 77 fits into 370 4 times, leaving a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 10010.94805194
Subtracting 308 from 370 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 10010.94805194, and the remainder is 6.2e-08.
