77379772 divided by 686 
We're looking to find how many times 686 goes into 77379772.

Moving on to step 1:
686 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 686

Going ahead to step 2:
When dividing 77 by 686, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (3) of the dividend behind the 77 and repeat the process: 773 / 686

Moving on to step 3:
When dividing 773 by 686, we get 1 with a remainder of 87.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 686 from 773 and we're left with 87.
Grab the next digit (7) from the dividend, add it to 87, then carry on: 877 / 686

Let's proceed to step 4:
686 goes into 877 1 times with a remainder of 191.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 686 from 877, we get 191.
Fetch the next digit (9) from the dividend, attach it to 191 and continue: 1919 / 686

Advancing to step 5:
If we divide 1919 by 686, we get 2 and a remainder of 547.
Write down 2 as next digit of the result. 
Result so far: 112.0
If we take 1372 away from 1919, we end up with 547.
Fetch the next digit (7) from the dividend, attach it to 547 and continue: 5477 / 686

Going ahead to step 6:
5477 divided by 686 is 7 with a remainder of 675.
Write down 7 as next digit of the result. 
Result so far: 1127.0
The remainder is 675 after subtracting 4802 from 5477.
Take the next digit (7) from the dividend and append it to 675, then repeat: 6757 / 686

On to step 7:
When dividing 6757 by 686, we get 9 with a remainder of 583.
The next digit of our result is 9. 
Result so far: 11279.0
If we take 6174 away from 6757, we end up with 583.
Bring next digit (2) of the dividend behind the 583 and repeat the process: 5832 / 686

Step 8:
686 goes into 5832 8 times with a remainder of 344.
Put 8 as the next digit of the answer. 
Result so far: 112798.0
Subtract 5488 from 5832 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 9:
When dividing 3440 by 686, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 112798.5
The remainder is 10 after subtracting 3430 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
100 divided by 686 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 112798.5
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
The number 686 fits into 1000 1 times, leaving a remainder of 314.
The next digit of our result is 1. 
Result so far: 112798.501
Subtract 686 from 1000 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 12:
3140 divided by 686 is 4 with a remainder of 396.
Use 4 as the next digit of our solution. 
Result so far: 112798.5014
Subtract 2744 from 3140 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 13:
When dividing 3960 by 686, we get 5 with a remainder of 530.
The number 5 becomes the next digit in our result. 
Result so far: 112798.50145
If we take 3430 away from 3960, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 14:
The number 686 fits into 5300 7 times, leaving a remainder of 498.
Put 7 as the next digit of the answer. 
Result so far: 112798.501457
Deduct 4802 from 5300 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Moving on to step 15:
4980 divided by 686 is 7 with a remainder of 178.
Record the quotient 7 as the next digit in the result. 
Result so far: 112798.5014577
If we take 4802 away from 4980, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

In conclusion, the division gives 112798.5014577 with a balance of 1.78e-06.
