668964 ÷ 73 
Our goal is to divide 668964 by 73.

Step 1:
73 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 73

Step 2:
73 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
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

Going ahead to step 3:
If we divide 668 by 73, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 657 from 668 to get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 73

Step 4:
73 goes into 119 1 times with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtract 73 from 119 to get 46.
Append the next digit (6) from the dividend to 46 and continue with: 466 / 73

Advancing to step 5:
73 can be fit into 466 6 times, resulting in a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 916.0
If we subtract 438 from 466, we get 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 73

Let's proceed to step 6:
73 goes into 284 3 times with a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 9163.0
Subtract 219 from 284 to 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.

Advancing to step 7:
73 can be fit into 650 8 times, resulting in a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 9163.8
Subtract 584 from 650 to get 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 8:
When dividing 660 by 73, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 9163.89
Subtract 657 from 660 to get 3.
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 9:
73 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 9163.89
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 10:
73 goes into 300 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 9163.8904
Subtracting 292 from 300 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
When dividing 80 by 73, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 9163.89041
Deduct 73 from 80 and we're left 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.

Let's proceed to step 12:
73 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 9163.89041
Subtract 0 from 70 to 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.

On to step 13:
73 goes into 700 9 times with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 9163.8904109
If we take 657 away from 700, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 14:
If we divide 430 by 73, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 9163.89041095
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.

The final outcome is 9163.89041095, with a leftover of 6.5e-08.
