Let's divide 517686 by 73
We're looking to find how many times 73 goes into 517686.

Going ahead to step 1:
73 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 73

Going ahead to step 2:
If we divide 51 by 73, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Append the next digit (7) from the dividend to 51 and continue with: 517 / 73

Advancing to step 3:
The number 73 fits into 517 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 6 after subtracting 511 from 517.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 73

Step 4:
66 divided by 73 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 70.0
If we subtract 0 from 66, we get 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 73

On to step 5:
The number 73 fits into 668 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 709.0
If we subtract 657 from 668, we get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 73

Going ahead to step 6:
If we divide 116 by 73, we get 1 and a remainder of 43.
The next digit of our result is 1. 
Result so far: 7091.0
If we subtract 73 from 116, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
If we divide 430 by 73, we get 5 and a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 7091.5
If we subtract 365 from 430, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 8:
When dividing 650 by 73, we get 8 with a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 7091.58
If we take 584 away from 650, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
If we divide 660 by 73, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 7091.589
If we take 657 away from 660, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
73 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 7091.589
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
300 divided by 73 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 7091.58904
If we subtract 292 from 300, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
When dividing 80 by 73, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 7091.589041
If we subtract 73 from 80, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
If we divide 70 by 73, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 7091.589041
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
73 can be fit into 700 9 times, resulting in a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 7091.58904109
The remainder is 43 after subtracting 657 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 7091.58904109 and a remainder of 4.3e-08.
