Let's divide 21678160 by 577
We want to divide 21678160 by 577.

On to step 1:
2 divided by 577 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 577

Advancing to step 2:
577 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 577

On to step 3:
If we divide 216 by 577, we get 0 and a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 216, we get 216.
Append the next digit (7) from the dividend to 216 and continue with: 2167 / 577

Advancing to step 4:
577 can be fit into 2167 3 times, resulting in a remainder of 436.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 436 after subtracting 1731 from 2167.
Fetch the next digit (8) from the dividend, attach it to 436 and continue: 4368 / 577

Step 5:
If we divide 4368 by 577, we get 7 and a remainder of 329.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 329 after subtracting 4039 from 4368.
Bring next digit (1) of the dividend behind the 329 and repeat the process: 3291 / 577

Advancing to step 6:
3291 divided by 577 is 5 with a remainder of 406.
Use 5 as the next digit of our solution. 
Result so far: 375.0
Deduct 2885 from 3291 and we're left with 406.
Grab the next digit (6) from the dividend, add it to 406, then carry on: 4066 / 577

Let's proceed to step 7:
4066 divided by 577 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 3757.0
If we subtract 4039 from 4066, we get 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 577

Advancing to step 8:
The number 577 fits into 270 0 times, leaving a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 37570.0
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 9:
577 goes into 2700 4 times with a remainder of 392.
Record the quotient 4 as the next digit in the result. 
Result so far: 37570.4
Subtract 2308 from 2700 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 10:
When dividing 3920 by 577, we get 6 with a remainder of 458.
Put 6 as the next digit of the answer. 
Result so far: 37570.46
If we take 3462 away from 3920, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Moving on to step 11:
The number 577 fits into 4580 7 times, leaving a remainder of 541.
The next digit of our result is 7. 
Result so far: 37570.467
The remainder is 541 after subtracting 4039 from 4580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

On to step 12:
When dividing 5410 by 577, we get 9 with a remainder of 217.
Write down 9 as next digit of the result. 
Result so far: 37570.4679
If we take 5193 away from 5410, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Step 13:
2170 divided by 577 is 3 with a remainder of 439.
The next digit of our result is 3. 
Result so far: 37570.46793
Subtracting 1731 from 2170 leaves us with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Let's proceed to step 14:
The number 577 fits into 4390 7 times, leaving a remainder of 351.
The next digit of our result is 7. 
Result so far: 37570.467937
Subtract 4039 from 4390 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 15:
The number 577 fits into 3510 6 times, leaving a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 37570.4679376
The remainder is 48 after subtracting 3462 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 16:
480 divided by 577 is 0 with a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 37570.4679376
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final outcome is 37570.4679376, with a leftover of 4.8e-07.
