171289 ÷ 77 
We want to figure out the number of times 171289 can be divided by 77.

Moving on to step 1:
1 divided by 77 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 77

On to step 2:
17 divided by 77 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 77

Step 3:
When dividing 171 by 77, we get 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 17 after subtracting 154 from 171.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 77

Step 4:
172 divided by 77 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtracting 154 from 172 leaves us with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 77

Let's proceed to step 5:
When dividing 188 by 77, we get 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 222.0
If we take 154 away from 188, we end up with 34.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 77

Step 6:
When dividing 349 by 77, we get 4 with a remainder of 41.
Use 4 as the next digit of our solution. 
Result so far: 2224.0
If we take 308 away from 349, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
77 can be fit into 410 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2224.5
If we take 385 away from 410, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
77 can be fit into 250 3 times, resulting in a remainder of 19.
The next digit of our result is 3. 
Result so far: 2224.53
If we subtract 231 from 250, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
77 can be fit into 190 2 times, resulting in a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 2224.532
The remainder is 36 after subtracting 154 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
77 goes into 360 4 times with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 2224.5324
Subtract 308 from 360 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
When dividing 520 by 77, we get 6 with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 2224.53246
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
If we divide 580 by 77, we get 7 and a remainder of 41.
The next digit of our result is 7. 
Result so far: 2224.532467
If we subtract 539 from 580, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 13:
When dividing 410 by 77, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 2224.5324675
If we take 385 away from 410, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
77 can be fit into 250 3 times, resulting in a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 2224.53246753
If we take 231 away from 250, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 2224.53246753, and the remainder is 1.9e-08.
