80325083 divided by 686 
Let's see how many times 686 fits into 80325083.

Going ahead to step 1:
8 divided by 686 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 686

Going ahead to step 2:
80 divided by 686 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 686

Let's proceed to step 3:
If we divide 803 by 686, we get 1 and a remainder of 117.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 686 from 803 leaves us with 117.
Grab the next digit (2) from the dividend, add it to 117, then carry on: 1172 / 686

Moving on to step 4:
If we divide 1172 by 686, we get 1 and a remainder of 486.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 686 from 1172 to get 486.
Fetch the next digit (5) from the dividend, attach it to 486 and continue: 4865 / 686

Advancing to step 5:
When dividing 4865 by 686, we get 7 with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 117.0
The remainder is 63 after subtracting 4802 from 4865.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 686

On to step 6:
If we divide 630 by 686, we get 0 and a remainder of 630.
The number 0 becomes the next digit in our result. 
Result so far: 1170.0
Deduct 0 from 630 and we're left with 630.
Append the next digit (8) from the dividend to 630 and continue with: 6308 / 686

Step 7:
When dividing 6308 by 686, we get 9 with a remainder of 134.
The number 9 becomes the next digit in our result. 
Result so far: 11709.0
If we subtract 6174 from 6308, we get 134.
Append the next digit (3) from the dividend to 134 and continue with: 1343 / 686

Step 8:
686 can be fit into 1343 1 times, resulting in a remainder of 657.
Put 1 as the next digit of the answer. 
Result so far: 117091.0
If we take 686 away from 1343, we end up with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Let's proceed to step 9:
When dividing 6570 by 686, we get 9 with a remainder of 396.
The number 9 becomes the next digit in our result. 
Result so far: 117091.9
Subtracting 6174 from 6570 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 10:
686 goes into 3960 5 times with a remainder of 530.
Write down 5 as next digit of the result. 
Result so far: 117091.95
Subtract 3430 from 3960 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 11:
When dividing 5300 by 686, we get 7 with a remainder of 498.
The next digit of our result is 7. 
Result so far: 117091.957
If we take 4802 away from 5300, we end up 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.

On to step 12:
When dividing 4980 by 686, we get 7 with a remainder of 178.
The number 7 becomes the next digit in our result. 
Result so far: 117091.9577
Subtracting 4802 from 4980 leaves us 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.

The final outcome is 117091.9577, with a leftover of 0.00178.
