We look at the division of 518161 by 73 
We want to figure out the number of times 518161 can be divided by 73.

Let's proceed to step 1:
When dividing 5 by 73, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 73

Going ahead to step 2:
When dividing 51 by 73, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 73

Advancing to step 3:
If we divide 518 by 73, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 511 away from 518, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 73

Step 4:
The number 73 fits into 71 0 times, leaving a remainder of 71.
The next digit of our result is 0. 
Result so far: 70.0
The remainder is 71 after subtracting 0 from 71.
Take the next digit (6) from the dividend and append it to 71, then repeat: 716 / 73

Moving on to step 5:
73 goes into 716 9 times with a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 709.0
Subtracting 657 from 716 leaves us with 59.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 73

Step 6:
The number 73 fits into 591 8 times, leaving a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 7098.0
Subtracting 584 from 591 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 73 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 7098.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
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: 7098.09
Subtract 657 from 700 to 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.

Let's proceed to step 9:
The number 73 fits into 430 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 7098.095
If we take 365 away from 430, we end up with 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 10:
If we divide 650 by 73, we get 8 and a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 7098.0958
The remainder is 66 after subtracting 584 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
73 can be fit into 660 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 7098.09589
The remainder is 3 after subtracting 657 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
73 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7098.09589
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
When dividing 300 by 73, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 7098.0958904
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.

Step 14:
73 can be fit into 80 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 7098.09589041
Subtract 73 from 80 to 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.

After the division, we end up with 7098.09589041 and a remainder of 7e-09.
