77349984 ÷ 770 
We want to divide 77349984 by 770.

Advancing to step 1:
If we divide 7 by 770, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
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 / 770

Step 2:
770 goes into 77 0 times with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 770

Moving on to step 3:
The number 770 fits into 773 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 770 from 773 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 770

On to step 4:
770 can be fit into 34 0 times, resulting in a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 34 leaves us with 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 770

Step 5:
The number 770 fits into 349 0 times, leaving a remainder of 349.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Deduct 0 from 349 and we're left with 349.
Take the next digit (9) from the dividend and append it to 349, then repeat: 3499 / 770

Going ahead to step 6:
770 goes into 3499 4 times with a remainder of 419.
The number 4 becomes the next digit in our result. 
Result so far: 1004.0
Deduct 3080 from 3499 and we're left with 419.
Include the next digit (8) from the dividend after 419, then repeat: 4198 / 770

Going ahead to step 7:
770 can be fit into 4198 5 times, resulting in a remainder of 348.
The number 5 becomes the next digit in our result. 
Result so far: 10045.0
Subtracting 3850 from 4198 leaves us with 348.
Fetch the next digit (4) from the dividend, attach it to 348 and continue: 3484 / 770

Let's proceed to step 8:
The number 770 fits into 3484 4 times, leaving a remainder of 404.
The next digit of our result is 4. 
Result so far: 100454.0
Subtract 3080 from 3484 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 9:
770 goes into 4040 5 times with a remainder of 190.
The next digit of our result is 5. 
Result so far: 100454.5
Deduct 3850 from 4040 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
If we divide 1900 by 770, we get 2 and a remainder of 360.
Record the quotient 2 as the next digit in the result. 
Result so far: 100454.52
If we take 1540 away from 1900, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 11:
The number 770 fits into 3600 4 times, leaving a remainder of 520.
The next digit of our result is 4. 
Result so far: 100454.524
Deduct 3080 from 3600 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 12:
If we divide 5200 by 770, we get 6 and a remainder of 580.
Use 6 as the next digit of our solution. 
Result so far: 100454.5246
Subtract 4620 from 5200 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 13:
5800 divided by 770 is 7 with a remainder of 410.
Use 7 as the next digit of our solution. 
Result so far: 100454.52467
Subtracting 5390 from 5800 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 14:
770 goes into 4100 5 times with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 100454.524675
Deduct 3850 from 4100 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 15:
2500 divided by 770 is 3 with a remainder of 190.
Use 3 as the next digit of our solution. 
Result so far: 100454.5246753
If we take 2310 away from 2500, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 16:
770 can be fit into 1900 2 times, resulting in a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 100454.52467532
The remainder is 360 after subtracting 1540 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final outcome is 100454.52467532, with a leftover of 3.6e-07.
