We're dividing 77777665 by 171 
Let's see how many times 171 fits into 77777665.

Let's proceed to step 1:
If we divide 7 by 171, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 171

Moving on to step 2:
If we divide 77 by 171, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Grab the next digit (7) from the dividend, add it to 77, then carry on: 777 / 171

On to step 3:
171 goes into 777 4 times with a remainder of 93.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 684 from 777, we get 93.
Fetch the next digit (7) from the dividend, attach it to 93 and continue: 937 / 171

Advancing to step 4:
171 can be fit into 937 5 times, resulting in a remainder of 82.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 82 after subtracting 855 from 937.
Include the next digit (7) from the dividend after 82, then repeat: 827 / 171

On to step 5:
If we divide 827 by 171, we get 4 and a remainder of 143.
Write down 4 as next digit of the result. 
Result so far: 454.0
The remainder is 143 after subtracting 684 from 827.
Bring next digit (6) of the dividend behind the 143 and repeat the process: 1436 / 171

Going ahead to step 6:
1436 divided by 171 is 8 with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 4548.0
Deduct 1368 from 1436 and we're left with 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 171

Moving on to step 7:
171 can be fit into 686 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 45484.0
If we take 684 away from 686, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 171

Moving on to step 8:
171 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 454840.0
Subtract 0 from 25 to get 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 9:
If we divide 250 by 171, we get 1 and a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 454840.1
Subtract 171 from 250 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 10:
790 divided by 171 is 4 with a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 454840.14
Deduct 684 from 790 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 11:
The number 171 fits into 1060 6 times, leaving a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 454840.146
The remainder is 34 after subtracting 1026 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
340 divided by 171 is 1 with a remainder of 169.
Record the quotient 1 as the next digit in the result. 
Result so far: 454840.1461
Deduct 171 from 340 and we're left with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 13:
If we divide 1690 by 171, we get 9 and a remainder of 151.
The number 9 becomes the next digit in our result. 
Result so far: 454840.14619
Subtract 1539 from 1690 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 14:
When dividing 1510 by 171, we get 8 with a remainder of 142.
Use 8 as the next digit of our solution. 
Result so far: 454840.146198
Subtract 1368 from 1510 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 15:
1420 divided by 171 is 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 454840.1461988
Subtract 1368 from 1420 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.

In conclusion, the division gives 454840.1461988 with a balance of 5.2e-07.
