80668567 divided by 408 
We want to divide 80668567 by 408.

Moving on to step 1:
8 divided by 408 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 408

Step 2:
80 divided by 408 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 408

Advancing to step 3:
When dividing 806 by 408, we get 1 with a remainder of 398.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 408 from 806, we get 398.
Include the next digit (6) from the dividend after 398, then repeat: 3986 / 408

Going ahead to step 4:
3986 divided by 408 is 9 with a remainder of 314.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 3672 away from 3986, we end up with 314.
Bring next digit (8) of the dividend behind the 314 and repeat the process: 3148 / 408

Advancing to step 5:
3148 divided by 408 is 7 with a remainder of 292.
Put 7 as the next digit of the answer. 
Result so far: 197.0
If we take 2856 away from 3148, we end up with 292.
Grab the next digit (5) from the dividend, add it to 292, then carry on: 2925 / 408

Step 6:
408 goes into 2925 7 times with a remainder of 69.
The next digit of our result is 7. 
Result so far: 1977.0
Subtract 2856 from 2925 to get 69.
Bring next digit (6) of the dividend behind the 69 and repeat the process: 696 / 408

Advancing to step 7:
408 can be fit into 696 1 times, resulting in a remainder of 288.
Record the quotient 1 as the next digit in the result. 
Result so far: 19771.0
If we subtract 408 from 696, we get 288.
Grab the next digit (7) from the dividend, add it to 288, then carry on: 2887 / 408

On to step 8:
The number 408 fits into 2887 7 times, leaving a remainder of 31.
The next digit of our result is 7. 
Result so far: 197717.0
If we take 2856 away from 2887, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
408 can be fit into 310 0 times, resulting in a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 197717.0
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 10:
3100 divided by 408 is 7 with a remainder of 244.
Record the quotient 7 as the next digit in the result. 
Result so far: 197717.07
The remainder is 244 after subtracting 2856 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 11:
2440 divided by 408 is 5 with a remainder of 400.
Put 5 as the next digit of the answer. 
Result so far: 197717.075
The remainder is 400 after subtracting 2040 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
When dividing 4000 by 408, we get 9 with a remainder of 328.
The number 9 becomes the next digit in our result. 
Result so far: 197717.0759
Deduct 3672 from 4000 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 13:
408 goes into 3280 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 197717.07598
Subtracting 3264 from 3280 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
408 can be fit into 160 0 times, resulting in a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 197717.07598
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 15:
408 can be fit into 1600 3 times, resulting in a remainder of 376.
Put 3 as the next digit of the answer. 
Result so far: 197717.0759803
Subtract 1224 from 1600 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 16:
The number 408 fits into 3760 9 times, leaving a remainder of 88.
Record the quotient 9 as the next digit in the result. 
Result so far: 197717.07598039
Subtract 3672 from 3760 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

In conclusion, the division gives 197717.07598039 with a balance of 8.8e-08.
