172710 divided by 78 
Let's see how many times 78 fits into 172710.

Going ahead to step 1:
78 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 78

On to step 2:
The number 78 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 78

On to step 3:
172 divided by 78 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 156 away from 172, we end up with 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 78

Step 4:
78 can be fit into 167 2 times, resulting in a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 156 from 167 and we're left with 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 78

Going ahead to step 5:
When dividing 111 by 78, we get 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 221.0
If we subtract 78 from 111, we get 33.
Include the next digit (0) from the dividend after 33, then repeat: 330 / 78

Let's proceed to step 6:
If we divide 330 by 78, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 2214.0
Deduct 312 from 330 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
When dividing 180 by 78, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2214.2
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
78 goes into 240 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 2214.23
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
60 divided by 78 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 2214.23
If we subtract 0 from 60, 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 10:
If we divide 600 by 78, we get 7 and a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 2214.2307
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
540 divided by 78 is 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 2214.23076
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
When dividing 720 by 78, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 2214.230769
Subtracting 702 from 720 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
If we divide 180 by 78, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 2214.2307692
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
If we divide 240 by 78, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 2214.23076923
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 2214.23076923 with a remaining 6e-09.
