We divide 209485 by 77
We're looking to find how many times 77 goes into 209485.

Step 1:
The number 77 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 77

Step 2:
If we divide 20 by 77, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 77

Moving on to step 3:
209 divided by 77 is 2 with a remainder of 55.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 55 after subtracting 154 from 209.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 77

Step 4:
554 divided by 77 is 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 15 after subtracting 539 from 554.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 77

On to step 5:
77 can be fit into 158 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 272.0
The remainder is 4 after subtracting 154 from 158.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 77

On to step 6:
45 divided by 77 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 2720.0
If we take 0 away from 45, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 7:
77 goes into 450 5 times with a remainder of 65.
The next digit of our result is 5. 
Result so far: 2720.5
Subtract 385 from 450 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 8:
The number 77 fits into 650 8 times, leaving a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 2720.58
Subtracting 616 from 650 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
If we divide 340 by 77, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 2720.584
Subtracting 308 from 340 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
When dividing 320 by 77, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 2720.5844
Subtracting 308 from 320 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 2720.5844 and a remainder of 0.00012.
