78985 ÷ 77 
We want to figure out the number of times 78985 can be divided by 77.

Moving on to step 1:
77 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 77

Step 2:
77 can be fit into 78 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 77 away from 78, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 77

Moving on to step 3:
If we divide 19 by 77, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 19, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 77

Advancing to step 4:
77 goes into 198 2 times with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we take 154 away from 198, we end up with 44.
Take the next digit (5) from the dividend and append it to 44, then repeat: 445 / 77

On to step 5:
445 divided by 77 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 1025.0
If we subtract 385 from 445, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 6:
77 goes into 600 7 times with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 1025.7
If we subtract 539 from 600, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 7:
77 goes into 610 7 times with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 1025.77
If we subtract 539 from 610, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 1025.77, and the remainder is 0.071.
