77881405 ÷ 665 
Our goal is to divide 77881405 by 665.

Going ahead to step 1:
665 can be fit into 7 0 times, resulting in 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 / 665

On to step 2:
When dividing 77 by 665, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 665

Moving on to step 3:
When dividing 778 by 665, we get 1 with a remainder of 113.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 665 from 778, we get 113.
Fetch the next digit (8) from the dividend, attach it to 113 and continue: 1138 / 665

Step 4:
665 goes into 1138 1 times with a remainder of 473.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 665 away from 1138, we end up with 473.
Grab the next digit (1) from the dividend, add it to 473, then carry on: 4731 / 665

Advancing to step 5:
4731 divided by 665 is 7 with a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 117.0
If we subtract 4655 from 4731, we get 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 665

Step 6:
If we divide 764 by 665, we get 1 and a remainder of 99.
Use 1 as the next digit of our solution. 
Result so far: 1171.0
Subtracting 665 from 764 leaves us with 99.
Bring next digit (0) of the dividend behind the 99 and repeat the process: 990 / 665

On to step 7:
665 can be fit into 990 1 times, resulting in a remainder of 325.
Write down 1 as next digit of the result. 
Result so far: 11711.0
If we subtract 665 from 990, we get 325.
Take the next digit (5) from the dividend and append it to 325, then repeat: 3255 / 665

Step 8:
665 can be fit into 3255 4 times, resulting in a remainder of 595.
Put 4 as the next digit of the answer. 
Result so far: 117114.0
The remainder is 595 after subtracting 2660 from 3255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Let's proceed to step 9:
If we divide 5950 by 665, we get 8 and a remainder of 630.
The next digit of our result is 8. 
Result so far: 117114.8
If we take 5320 away from 5950, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 10:
The number 665 fits into 6300 9 times, leaving a remainder of 315.
Use 9 as the next digit of our solution. 
Result so far: 117114.89
If we subtract 5985 from 6300, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 11:
When dividing 3150 by 665, we get 4 with a remainder of 490.
The number 4 becomes the next digit in our result. 
Result so far: 117114.894
The remainder is 490 after subtracting 2660 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 12:
The number 665 fits into 4900 7 times, leaving a remainder of 245.
The next digit of our result is 7. 
Result so far: 117114.8947
The remainder is 245 after subtracting 4655 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 13:
The number 665 fits into 2450 3 times, leaving a remainder of 455.
Put 3 as the next digit of the answer. 
Result so far: 117114.89473
If we subtract 1995 from 2450, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Step 14:
665 can be fit into 4550 6 times, resulting in a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 117114.894736
Deduct 3990 from 4550 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 15:
665 can be fit into 5600 8 times, resulting in a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 117114.8947368
Deduct 5320 from 5600 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 16:
When dividing 2800 by 665, we get 4 with a remainder of 140.
Record the quotient 4 as the next digit in the result. 
Result so far: 117114.89473684
Subtract 2660 from 2800 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 117114.89473684, with a leftover of 1.4e-07.
