We're dividing 81045023 by 686 
Let's see how many times 686 fits into 81045023.

Advancing to step 1:
When dividing 8 by 686, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 686

Let's proceed to step 2:
When dividing 81 by 686, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 686

Moving on to step 3:
If we divide 810 by 686, we get 1 and a remainder of 124.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 686 from 810, we get 124.
Include the next digit (4) from the dividend after 124, then repeat: 1244 / 686

Moving on to step 4:
1244 divided by 686 is 1 with a remainder of 558.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 686 from 1244 and we're left with 558.
Include the next digit (5) from the dividend after 558, then repeat: 5585 / 686

Step 5:
The number 686 fits into 5585 8 times, leaving a remainder of 97.
Use 8 as the next digit of our solution. 
Result so far: 118.0
Deduct 5488 from 5585 and we're left with 97.
Append the next digit (0) from the dividend to 97 and continue with: 970 / 686

Moving on to step 6:
686 goes into 970 1 times with a remainder of 284.
Write down 1 as next digit of the result. 
Result so far: 1181.0
If we take 686 away from 970, we end up with 284.
Bring next digit (2) of the dividend behind the 284 and repeat the process: 2842 / 686

Let's proceed to step 7:
686 can be fit into 2842 4 times, resulting in a remainder of 98.
Write down 4 as next digit of the result. 
Result so far: 11814.0
Subtract 2744 from 2842 to get 98.
Append the next digit (3) from the dividend to 98 and continue with: 983 / 686

Let's proceed to step 8:
983 divided by 686 is 1 with a remainder of 297.
Write down 1 as next digit of the result. 
Result so far: 118141.0
Deduct 686 from 983 and we're left with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 9:
686 can be fit into 2970 4 times, resulting in a remainder of 226.
The next digit of our result is 4. 
Result so far: 118141.4
If we take 2744 away from 2970, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 10:
686 can be fit into 2260 3 times, resulting in a remainder of 202.
Put 3 as the next digit of the answer. 
Result so far: 118141.43
The remainder is 202 after subtracting 2058 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 11:
686 can be fit into 2020 2 times, resulting in a remainder of 648.
Use 2 as the next digit of our solution. 
Result so far: 118141.432
Subtract 1372 from 2020 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 12:
6480 divided by 686 is 9 with a remainder of 306.
The next digit of our result is 9. 
Result so far: 118141.4329
Deduct 6174 from 6480 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 13:
686 can be fit into 3060 4 times, resulting in a remainder of 316.
The next digit of our result is 4. 
Result so far: 118141.43294
If we take 2744 away from 3060, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 14:
If we divide 3160 by 686, we get 4 and a remainder of 416.
Put 4 as the next digit of the answer. 
Result so far: 118141.432944
The remainder is 416 after subtracting 2744 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

After the division, we end up with 118141.432944 and a remainder of 4.16e-05.
