77860341 ÷ 689 
Our goal is to divide 77860341 by 689.

Advancing to step 1:
When dividing 7 by 689, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 689

Moving on to step 2:
77 divided by 689 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 689

Going ahead to step 3:
The number 689 fits into 778 1 times, leaving a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 689 away from 778, we end up with 89.
Take the next digit (6) from the dividend and append it to 89, then repeat: 896 / 689

On to step 4:
689 goes into 896 1 times with a remainder of 207.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 689 from 896 and we're left with 207.
Include the next digit (0) from the dividend after 207, then repeat: 2070 / 689

Let's proceed to step 5:
689 goes into 2070 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 113.0
The remainder is 3 after subtracting 2067 from 2070.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 689

Advancing to step 6:
33 divided by 689 is 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 1130.0
If we subtract 0 from 33, we get 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 689

Moving on to step 7:
When dividing 334 by 689, we get 0 with a remainder of 334.
Use 0 as the next digit of our solution. 
Result so far: 11300.0
The remainder is 334 after subtracting 0 from 334.
Bring next digit (1) of the dividend behind the 334 and repeat the process: 3341 / 689

On to step 8:
689 goes into 3341 4 times with a remainder of 585.
Write down 4 as next digit of the result. 
Result so far: 113004.0
Deduct 2756 from 3341 and we're left with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Going ahead to step 9:
When dividing 5850 by 689, we get 8 with a remainder of 338.
The number 8 becomes the next digit in our result. 
Result so far: 113004.8
Subtracting 5512 from 5850 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 10:
If we divide 3380 by 689, we get 4 and a remainder of 624.
The next digit of our result is 4. 
Result so far: 113004.84
If we subtract 2756 from 3380, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 11:
6240 divided by 689 is 9 with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 113004.849
If we take 6201 away from 6240, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 12:
689 can be fit into 390 0 times, resulting in a remainder of 390.
Record the quotient 0 as the next digit in the result. 
Result so far: 113004.849
Subtract 0 from 390 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 13:
689 can be fit into 3900 5 times, resulting in a remainder of 455.
Write down 5 as next digit of the result. 
Result so far: 113004.84905
Subtracting 3445 from 3900 leaves us with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 14:
689 can be fit into 4550 6 times, resulting in a remainder of 416.
Write down 6 as next digit of the result. 
Result so far: 113004.849056
Subtract 4134 from 4550 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 15:
4160 divided by 689 is 6 with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 113004.8490566
Deduct 4134 from 4160 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 113004.8490566 with a remainder of 2.6e-07.
