We look at the division of 73166539 by 965 
We're looking to find how many times 965 goes into 73166539.

Step 1:
965 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 965

Step 2:
73 divided by 965 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 965

Step 3:
The number 965 fits into 731 0 times, leaving a remainder of 731.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 731 leaves us with 731.
Take the next digit (6) from the dividend and append it to 731, then repeat: 7316 / 965

On to step 4:
If we divide 7316 by 965, we get 7 and a remainder of 561.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 6755 from 7316 leaves us with 561.
Append the next digit (6) from the dividend to 561 and continue with: 5616 / 965

Advancing to step 5:
If we divide 5616 by 965, we get 5 and a remainder of 791.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Deduct 4825 from 5616 and we're left with 791.
Fetch the next digit (5) from the dividend, attach it to 791 and continue: 7915 / 965

Moving on to step 6:
965 can be fit into 7915 8 times, resulting in a remainder of 195.
Write down 8 as next digit of the result. 
Result so far: 758.0
Subtract 7720 from 7915 to get 195.
Bring next digit (3) of the dividend behind the 195 and repeat the process: 1953 / 965

Going ahead to step 7:
1953 divided by 965 is 2 with a remainder of 23.
The next digit of our result is 2. 
Result so far: 7582.0
Subtract 1930 from 1953 to get 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 965

Advancing to step 8:
When dividing 239 by 965, we get 0 with a remainder of 239.
Record the quotient 0 as the next digit in the result. 
Result so far: 75820.0
If we subtract 0 from 239, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 9:
The number 965 fits into 2390 2 times, leaving a remainder of 460.
Put 2 as the next digit of the answer. 
Result so far: 75820.2
If we subtract 1930 from 2390, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 10:
4600 divided by 965 is 4 with a remainder of 740.
Record the quotient 4 as the next digit in the result. 
Result so far: 75820.24
Subtract 3860 from 4600 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 11:
965 goes into 7400 7 times with a remainder of 645.
The next digit of our result is 7. 
Result so far: 75820.247
Subtract 6755 from 7400 to get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Advancing to step 12:
If we divide 6450 by 965, we get 6 and a remainder of 660.
Write down 6 as next digit of the result. 
Result so far: 75820.2476
Subtract 5790 from 6450 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 13:
965 goes into 6600 6 times with a remainder of 810.
Use 6 as the next digit of our solution. 
Result so far: 75820.24766
Deduct 5790 from 6600 and we're left with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

The final result is 75820.24766 with a remainder of 0.00081.
