77552317 ÷ 770 
We want to divide 77552317 by 770.

Let's proceed to step 1:
7 divided by 770 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 770

Moving on to step 2:
770 can be fit into 77 0 times, resulting in 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.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 770

Let's proceed to step 3:
770 goes into 775 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 770 from 775 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 770

Let's proceed to step 4:
If we divide 55 by 770, we get 0 and a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 55 to get 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 770

On to step 5:
770 goes into 552 0 times with a remainder of 552.
The next digit of our result is 0. 
Result so far: 100.0
Subtracting 0 from 552 leaves us with 552.
Grab the next digit (3) from the dividend, add it to 552, then carry on: 5523 / 770

On to step 6:
770 can be fit into 5523 7 times, resulting in a remainder of 133.
The next digit of our result is 7. 
Result so far: 1007.0
If we take 5390 away from 5523, we end up with 133.
Grab the next digit (1) from the dividend, add it to 133, then carry on: 1331 / 770

Step 7:
When dividing 1331 by 770, we get 1 with a remainder of 561.
Write down 1 as next digit of the result. 
Result so far: 10071.0
If we subtract 770 from 1331, we get 561.
Fetch the next digit (7) from the dividend, attach it to 561 and continue: 5617 / 770

On to step 8:
The number 770 fits into 5617 7 times, leaving a remainder of 227.
Use 7 as the next digit of our solution. 
Result so far: 100717.0
The remainder is 227 after subtracting 5390 from 5617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Going ahead to step 9:
770 goes into 2270 2 times with a remainder of 730.
The number 2 becomes the next digit in our result. 
Result so far: 100717.2
The remainder is 730 after subtracting 1540 from 2270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 10:
When dividing 7300 by 770, we get 9 with a remainder of 370.
Record the quotient 9 as the next digit in the result. 
Result so far: 100717.29
Subtract 6930 from 7300 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 11:
3700 divided by 770 is 4 with a remainder of 620.
Put 4 as the next digit of the answer. 
Result so far: 100717.294
If we take 3080 away from 3700, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 12:
770 goes into 6200 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 100717.2948
Subtract 6160 from 6200 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.

Going ahead to step 13:
770 can be fit into 400 0 times, resulting in a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 100717.2948
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 14:
4000 divided by 770 is 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 100717.294805
The remainder is 150 after subtracting 3850 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 15:
If we divide 1500 by 770, we get 1 and a remainder of 730.
The next digit of our result is 1. 
Result so far: 100717.2948051
If we take 770 away from 1500, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 16:
If we divide 7300 by 770, we get 9 and a remainder of 370.
Put 9 as the next digit of the answer. 
Result so far: 100717.29480519
Subtracting 6930 from 7300 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

In conclusion, the division gives 100717.29480519 with a balance of 3.7e-07.
