We divide 778447 by 77
We're looking to find how many times 77 goes into 778447.

Step 1:
When dividing 7 by 77, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 77

Step 2:
The number 77 fits into 77 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 77 from 77 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 77

Advancing to step 3:
If we divide 8 by 77, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 77

Advancing to step 4:
84 divided by 77 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Deduct 77 from 84 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 77

Let's proceed to step 5:
When dividing 74 by 77, we get 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 1010.0
Subtracting 0 from 74 leaves us with 74.
Bring next digit (7) of the dividend behind the 74 and repeat the process: 747 / 77

Going ahead to step 6:
747 divided by 77 is 9 with a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 10109.0
If we subtract 693 from 747, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
The number 77 fits into 540 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 10109.7
If we subtract 539 from 540, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
10 divided by 77 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10109.7
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 77 fits into 100 1 times, leaving a remainder of 23.
The next digit of our result is 1. 
Result so far: 10109.701
If we subtract 77 from 100, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
77 goes into 230 2 times with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 10109.7012
The remainder is 76 after subtracting 154 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 11:
77 can be fit into 760 9 times, resulting in a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 10109.70129
If we take 693 away from 760, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 12:
670 divided by 77 is 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 10109.701298
The remainder is 54 after subtracting 616 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
If we divide 540 by 77, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 10109.7012987
Deduct 539 from 540 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
If we divide 10 by 77, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 10109.7012987
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 10109.7012987 and a remainder of 1e-08.
