We divide 78738540 by 171
We want to divide 78738540 by 171.

On to step 1:
7 divided by 171 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 171

Advancing to step 2:
171 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 171

Advancing to step 3:
171 can be fit into 787 4 times, resulting in a remainder of 103.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 684 away from 787, we end up with 103.
Take the next digit (3) from the dividend and append it to 103, then repeat: 1033 / 171

Let's proceed to step 4:
171 goes into 1033 6 times with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 46.0
The remainder is 7 after subtracting 1026 from 1033.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 171

Moving on to step 5:
171 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 460.0
Subtract 0 from 78 to get 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 171

Step 6:
171 goes into 785 4 times with a remainder of 101.
Write down 4 as next digit of the result. 
Result so far: 4604.0
The remainder is 101 after subtracting 684 from 785.
Bring next digit (4) of the dividend behind the 101 and repeat the process: 1014 / 171

Step 7:
When dividing 1014 by 171, we get 5 with a remainder of 159.
The next digit of our result is 5. 
Result so far: 46045.0
If we subtract 855 from 1014, we get 159.
Append the next digit (0) from the dividend to 159 and continue with: 1590 / 171

Let's proceed to step 8:
171 can be fit into 1590 9 times, resulting in a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 460459.0
Deduct 1539 from 1590 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
171 goes into 510 2 times with a remainder of 168.
Record the quotient 2 as the next digit in the result. 
Result so far: 460459.2
The remainder is 168 after subtracting 342 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 10:
171 can be fit into 1680 9 times, resulting in a remainder of 141.
Put 9 as the next digit of the answer. 
Result so far: 460459.29
The remainder is 141 after subtracting 1539 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 11:
171 goes into 1410 8 times with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 460459.298
Subtract 1368 from 1410 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
If we divide 420 by 171, we get 2 and a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 460459.2982
Deduct 342 from 420 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 13:
If we divide 780 by 171, we get 4 and a remainder of 96.
The next digit of our result is 4. 
Result so far: 460459.29824
If we take 684 away from 780, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 14:
The number 171 fits into 960 5 times, leaving a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 460459.298245
The remainder is 105 after subtracting 855 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 15:
171 goes into 1050 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 460459.2982456
The remainder is 24 after subtracting 1026 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 16:
The number 171 fits into 240 1 times, leaving a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 460459.29824561
If we take 171 away from 240, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

In conclusion, the division gives 460459.29824561 with a balance of 6.9e-08.
