We look at the division of 774078 by 77 
We want to divide 774078 by 77.

On to step 1:
7 divided by 77 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
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

On to step 2:
77 goes into 77 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 77 from 77.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 77

Moving on to step 3:
If we divide 4 by 77, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 77

Moving on to step 4:
If we divide 40 by 77, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 77

Advancing to step 5:
If we divide 407 by 77, we get 5 and a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 1005.0
If we take 385 away from 407, we end up with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 77

Moving on to step 6:
When dividing 228 by 77, we get 2 with a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 10052.0
If we take 154 away from 228, we end up 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.

Step 7:
The number 77 fits into 740 9 times, leaving a remainder of 47.
The next digit of our result is 9. 
Result so far: 10052.9
Subtract 693 from 740 to 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.

Advancing to step 8:
77 goes into 470 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10052.96
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.

Moving on to step 9:
77 can be fit into 80 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 10052.961
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:
77 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 10052.961
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
If we divide 300 by 77, we get 3 and a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 10052.96103
Subtracting 231 from 300 leaves us 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.

Moving on to step 12:
If we divide 690 by 77, we get 8 and a remainder of 74.
The next digit of our result is 8. 
Result so far: 10052.961038
If we subtract 616 from 690, 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.

Advancing to step 13:
If we divide 740 by 77, we get 9 and a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 10052.9610389
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.

On to step 14:
The number 77 fits into 470 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10052.96103896
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 quotient of the division is 10052.96103896, and the remainder is 8e-09.
