77720816 ÷ 377 
We want to divide 77720816 by 377.

On to step 1:
377 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 377

Moving on to step 2:
377 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 377

Moving on to step 3:
The number 377 fits into 777 2 times, leaving a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 23 after subtracting 754 from 777.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 377

Going ahead to step 4:
If we divide 232 by 377, we get 0 and a remainder of 232.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 232 after subtracting 0 from 232.
Append the next digit (0) from the dividend to 232 and continue with: 2320 / 377

Moving on to step 5:
2320 divided by 377 is 6 with a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 206.0
Subtract 2262 from 2320 to get 58.
Append the next digit (8) from the dividend to 58 and continue with: 588 / 377

Advancing to step 6:
377 can be fit into 588 1 times, resulting in a remainder of 211.
Use 1 as the next digit of our solution. 
Result so far: 2061.0
If we subtract 377 from 588, we get 211.
Include the next digit (1) from the dividend after 211, then repeat: 2111 / 377

Let's proceed to step 7:
377 can be fit into 2111 5 times, resulting in a remainder of 226.
The number 5 becomes the next digit in our result. 
Result so far: 20615.0
Subtracting 1885 from 2111 leaves us with 226.
Include the next digit (6) from the dividend after 226, then repeat: 2266 / 377

Let's proceed to step 8:
377 goes into 2266 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 206156.0
Subtract 2262 from 2266 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
If we divide 40 by 377, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 206156.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
The number 377 fits into 400 1 times, leaving a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 206156.01
Deduct 377 from 400 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 11:
The number 377 fits into 230 0 times, leaving a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 206156.01
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 12:
If we divide 2300 by 377, we get 6 and a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 206156.0106
Subtracting 2262 from 2300 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
377 can be fit into 380 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 206156.01061
If we take 377 away from 380, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
30 divided by 377 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 206156.01061
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 15:
When dividing 300 by 377, we get 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 206156.01061
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 206156.01061 with a balance of 3e-06.
