686519 divided by 73 
We want to figure out the number of times 686519 can be divided by 73.

On to step 1:
73 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 73

Advancing to step 2:
73 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 73

On to step 3:
The number 73 fits into 686 9 times, leaving a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 657 from 686, we get 29.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 73

Advancing to step 4:
When dividing 295 by 73, we get 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Deduct 292 from 295 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 73

On to step 5:
73 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 940.0
If we subtract 0 from 31, we get 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 73

Going ahead to step 6:
When dividing 319 by 73, we get 4 with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 9404.0
The remainder is 27 after subtracting 292 from 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
When dividing 270 by 73, we get 3 with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 9404.3
Subtract 219 from 270 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 8:
The number 73 fits into 510 6 times, leaving a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 9404.36
If we take 438 away from 510, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
If we divide 720 by 73, we get 9 and a remainder of 63.
The next digit of our result is 9. 
Result so far: 9404.369
Subtract 657 from 720 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 10:
The number 73 fits into 630 8 times, leaving a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 9404.3698
Subtract 584 from 630 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
If we divide 460 by 73, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 9404.36986
Deduct 438 from 460 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
When dividing 220 by 73, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 9404.369863
If we take 219 away from 220, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
If we divide 10 by 73, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 9404.369863
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
When dividing 100 by 73, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 9404.36986301
The remainder is 27 after subtracting 73 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 9404.36986301 and a remainder of 2.7e-08.
