1350 divided by 770 is 1 with a remainder of 580.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 770 from 1350 leaves us with 580.
Grab the next digit (6) from the dividend, add it to 580, then carry on: 5806 / 770

On to step 5:
When dividing 5806 by 770, we get 7 with a remainder of 416.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
The remainder is 416 after subtracting 5390 from 5806.
Append the next digit (1) from the dividend to 416 and continue with: 4161 / 770

Let's proceed to step 6:
4161 divided by 770 is 5 with a remainder of 311.
The next digit of our result is 5. 
Result so far: 1175.0
Subtracting 3850 from 4161 leaves us with 311.
Include the next digit (5) from the dividend after 311, then repeat: 3115 / 770

Going ahead to step 7:
3115 divided by 770 is 4 with a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 11754.0
Subtracting 3080 from 3115 leaves us with 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 770

Advancing to step 8:
770 can be fit into 354 0 times, resulting in a remainder of 354.
Record the quotient 0 as the next digit in the result. 
Result so far: 117540.0
If we take 0 away from 354, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 9:
3540 divided by 770 is 4 with a remainder of 460.
Put 4 as the next digit of the answer. 
Result so far: 117540.4
Subtract 3080 from 3540 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 10:
770 goes into 4600 5 times with a remainder of 750.
Write down 5 as next digit of the result. 
Result so far: 117540.45
If we take 3850 away from 4600, we end up with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 11:
770 can be fit into 7500 9 times, resulting in a remainder of 570.
Record the quotient 9 as the next digit in the result. 
Result so far: 117540.459
The remainder is 570 after subtracting 6930 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 12:
If we divide 5700 by 770, we get 7 and a remainder of 310.
The number 7 becomes the next digit in our result. 
Result so far: 117540.4597
If we subtract 5390 from 5700, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 13:
770 can be fit into 3100 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 117540.45974
If we subtract 3080 from 3100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
When dividing 200 by 770, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 117540.45974
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 15:
If we divide 2000 by 770, we get 2 and a remainder of 460.
Record the quotient 2 as the next digit in the result. 
Result so far: 117540.4597402
Subtract 1540 from 2000 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 16:
The number 770 fits into 4600 5 times, leaving a remainder of 750.
The number 5 becomes the next digit in our result. 
Result so far: 117540.45974025
If we take 3850 away from 4600, we end up with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

The final result is 117540.45974025 with a remainder of 7.5e-07.
