978485 divided by 77 
We want to figure out the number of times 978485 can be divided by 77.

On to step 1:
If we divide 9 by 77, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 77

Advancing to step 2:
97 divided by 77 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 77 from 97 to get 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 77

Let's proceed to step 3:
77 goes into 208 2 times with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 54 after subtracting 154 from 208.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 77

Moving on to step 4:
77 can be fit into 544 7 times, resulting in a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we subtract 539 from 544, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 77

Advancing to step 5:
77 can be fit into 58 0 times, resulting in a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 1270.0
Subtract 0 from 58 to get 58.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 77

Advancing to step 6:
585 divided by 77 is 7 with a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 12707.0
Subtracting 539 from 585 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
When dividing 460 by 77, we get 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 12707.5
Subtracting 385 from 460 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 8:
77 can be fit into 750 9 times, resulting in a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 12707.59
If we take 693 away from 750, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
If we divide 570 by 77, we get 7 and a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 12707.597
The remainder is 31 after subtracting 539 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
310 divided by 77 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 12707.5974
Deduct 308 from 310 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
20 divided by 77 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12707.5974
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
77 goes into 200 2 times with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 12707.597402
Subtract 154 from 200 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
77 can be fit into 460 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 12707.5974025
If we subtract 385 from 460, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 14:
77 goes into 750 9 times with a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 12707.59740259
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The quotient of the division is 12707.59740259, and the remainder is 5.7e-08.
