We divide 66915983 by 623
We want to figure out the number of times 66915983 can be divided by 623.

Moving on to step 1:
The number 623 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 623

Going ahead to step 2:
623 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 623

Going ahead to step 3:
623 goes into 669 1 times with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 623 away from 669, we end up with 46.
Bring next digit (1) of the dividend behind the 46 and repeat the process: 461 / 623

Step 4:
If we divide 461 by 623, we get 0 and a remainder of 461.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 461 to get 461.
Fetch the next digit (5) from the dividend, attach it to 461 and continue: 4615 / 623

Let's proceed to step 5:
623 goes into 4615 7 times with a remainder of 254.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
If we take 4361 away from 4615, we end up with 254.
Bring next digit (9) of the dividend behind the 254 and repeat the process: 2549 / 623

Advancing to step 6:
623 goes into 2549 4 times with a remainder of 57.
The number 4 becomes the next digit in our result. 
Result so far: 1074.0
If we take 2492 away from 2549, we end up with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 623

On to step 7:
623 can be fit into 578 0 times, resulting in a remainder of 578.
The number 0 becomes the next digit in our result. 
Result so far: 10740.0
Subtract 0 from 578 to get 578.
Append the next digit (3) from the dividend to 578 and continue with: 5783 / 623

On to step 8:
623 can be fit into 5783 9 times, resulting in a remainder of 176.
Use 9 as the next digit of our solution. 
Result so far: 107409.0
Subtract 5607 from 5783 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 9:
The number 623 fits into 1760 2 times, leaving a remainder of 514.
Put 2 as the next digit of the answer. 
Result so far: 107409.2
If we subtract 1246 from 1760, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 10:
5140 divided by 623 is 8 with a remainder of 156.
The number 8 becomes the next digit in our result. 
Result so far: 107409.28
The remainder is 156 after subtracting 4984 from 5140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 11:
When dividing 1560 by 623, we get 2 with a remainder of 314.
Write down 2 as next digit of the result. 
Result so far: 107409.282
The remainder is 314 after subtracting 1246 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 12:
3140 divided by 623 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 107409.2825
If we subtract 3115 from 3140, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
When dividing 250 by 623, we get 0 with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 107409.2825
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 14:
2500 divided by 623 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 107409.282504
Deduct 2492 from 2500 and we're left 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.

Advancing to step 15:
623 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 107409.282504
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
623 goes into 800 1 times with a remainder of 177.
Put 1 as the next digit of the answer. 
Result so far: 107409.28250401
If we take 623 away from 800, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Our division results in 107409.28250401 with a remaining 1.77e-07.
