We're dividing 77008602 by 686 
We want to figure out the number of times 77008602 can be divided by 686.

Going ahead to step 1:
686 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 686

Let's proceed to step 2:
686 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Bring next digit (0) of the dividend behind the 77 and repeat the process: 770 / 686

Step 3:
686 goes into 770 1 times with a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 84 after subtracting 686 from 770.
Grab the next digit (0) from the dividend, add it to 84, then carry on: 840 / 686

Let's proceed to step 4:
The number 686 fits into 840 1 times, leaving a remainder of 154.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 686 from 840 to get 154.
Grab the next digit (8) from the dividend, add it to 154, then carry on: 1548 / 686

Step 5:
686 goes into 1548 2 times with a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Subtract 1372 from 1548 to get 176.
Append the next digit (6) from the dividend to 176 and continue with: 1766 / 686

Advancing to step 6:
686 can be fit into 1766 2 times, resulting in a remainder of 394.
Put 2 as the next digit of the answer. 
Result so far: 1122.0
The remainder is 394 after subtracting 1372 from 1766.
Bring next digit (0) of the dividend behind the 394 and repeat the process: 3940 / 686

On to step 7:
3940 divided by 686 is 5 with a remainder of 510.
The number 5 becomes the next digit in our result. 
Result so far: 11225.0
Subtract 3430 from 3940 to get 510.
Fetch the next digit (2) from the dividend, attach it to 510 and continue: 5102 / 686

Going ahead to step 8:
686 goes into 5102 7 times with a remainder of 300.
Record the quotient 7 as the next digit in the result. 
Result so far: 112257.0
If we subtract 4802 from 5102, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 9:
3000 divided by 686 is 4 with a remainder of 256.
Record the quotient 4 as the next digit in the result. 
Result so far: 112257.4
If we subtract 2744 from 3000, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 10:
When dividing 2560 by 686, we get 3 with a remainder of 502.
Write down 3 as next digit of the result. 
Result so far: 112257.43
If we take 2058 away from 2560, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 11:
The number 686 fits into 5020 7 times, leaving a remainder of 218.
Write down 7 as next digit of the result. 
Result so far: 112257.437
If we subtract 4802 from 5020, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 12:
686 goes into 2180 3 times with a remainder of 122.
The next digit of our result is 3. 
Result so far: 112257.4373
Subtracting 2058 from 2180 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 13:
1220 divided by 686 is 1 with a remainder of 534.
Use 1 as the next digit of our solution. 
Result so far: 112257.43731
The remainder is 534 after subtracting 686 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Advancing to step 14:
5340 divided by 686 is 7 with a remainder of 538.
Put 7 as the next digit of the answer. 
Result so far: 112257.437317
Subtracting 4802 from 5340 leaves us with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 15:
When dividing 5380 by 686, we get 7 with a remainder of 578.
Put 7 as the next digit of the answer. 
Result so far: 112257.4373177
Subtract 4802 from 5380 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

The final outcome is 112257.4373177, with a leftover of 5.78e-06.
