53587862 ÷ 668 
We're looking to find how many times 668 goes into 53587862.

Let's proceed to step 1:
The number 668 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 668

Let's proceed to step 2:
668 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 668

Let's proceed to step 3:
668 can be fit into 535 0 times, resulting in a remainder of 535.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 535 after subtracting 0 from 535.
Fetch the next digit (8) from the dividend, attach it to 535 and continue: 5358 / 668

Going ahead to step 4:
When dividing 5358 by 668, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 14 after subtracting 5344 from 5358.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 668

Moving on to step 5:
147 divided by 668 is 0 with a remainder of 147.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we subtract 0 from 147, we get 147.
Fetch the next digit (8) from the dividend, attach it to 147 and continue: 1478 / 668

Advancing to step 6:
The number 668 fits into 1478 2 times, leaving a remainder of 142.
Record the quotient 2 as the next digit in the result. 
Result so far: 802.0
Deduct 1336 from 1478 and we're left with 142.
Fetch the next digit (6) from the dividend, attach it to 142 and continue: 1426 / 668

Moving on to step 7:
1426 divided by 668 is 2 with a remainder of 90.
Write down 2 as next digit of the result. 
Result so far: 8022.0
Deduct 1336 from 1426 and we're left with 90.
Bring next digit (2) of the dividend behind the 90 and repeat the process: 902 / 668

Moving on to step 8:
902 divided by 668 is 1 with a remainder of 234.
Write down 1 as next digit of the result. 
Result so far: 80221.0
If we subtract 668 from 902, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 9:
When dividing 2340 by 668, we get 3 with a remainder of 336.
Record the quotient 3 as the next digit in the result. 
Result so far: 80221.3
If we subtract 2004 from 2340, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 10:
3360 divided by 668 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 80221.35
The remainder is 20 after subtracting 3340 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
668 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 80221.35
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
668 can be fit into 2000 2 times, resulting in a remainder of 664.
The next digit of our result is 2. 
Result so far: 80221.3502
If we take 1336 away from 2000, we end up with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Let's proceed to step 13:
If we divide 6640 by 668, we get 9 and a remainder of 628.
Use 9 as the next digit of our solution. 
Result so far: 80221.35029
If we take 6012 away from 6640, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

On to step 14:
When dividing 6280 by 668, we get 9 with a remainder of 268.
Use 9 as the next digit of our solution. 
Result so far: 80221.350299
If we take 6012 away from 6280, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Our division results in 80221.350299 with a remaining 2.68e-05.
