54086657 ÷ 668 
We're looking to find how many times 668 goes into 54086657.

On to step 1:
The number 668 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 668

Going ahead to step 2:
668 can be fit into 54 0 times, resulting in a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 668

Step 3:
668 goes into 540 0 times with a remainder of 540.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 540, we end up with 540.
Fetch the next digit (8) from the dividend, attach it to 540 and continue: 5408 / 668

Step 4:
When dividing 5408 by 668, we get 8 with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 5344 from 5408 to get 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 668

Moving on to step 5:
The number 668 fits into 646 0 times, leaving a remainder of 646.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Deduct 0 from 646 and we're left with 646.
Include the next digit (6) from the dividend after 646, then repeat: 6466 / 668

On to step 6:
If we divide 6466 by 668, we get 9 and a remainder of 454.
Record the quotient 9 as the next digit in the result. 
Result so far: 809.0
The remainder is 454 after subtracting 6012 from 6466.
Include the next digit (5) from the dividend after 454, then repeat: 4545 / 668

On to step 7:
4545 divided by 668 is 6 with a remainder of 537.
Put 6 as the next digit of the answer. 
Result so far: 8096.0
Subtract 4008 from 4545 to get 537.
Grab the next digit (7) from the dividend, add it to 537, then carry on: 5377 / 668

Advancing to step 8:
5377 divided by 668 is 8 with a remainder of 33.
The next digit of our result is 8. 
Result so far: 80968.0
The remainder is 33 after subtracting 5344 from 5377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
If we divide 330 by 668, we get 0 and a remainder of 330.
The next digit of our result is 0. 
Result so far: 80968.0
Subtracting 0 from 330 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
3300 divided by 668 is 4 with a remainder of 628.
The number 4 becomes the next digit in our result. 
Result so far: 80968.04
Deduct 2672 from 3300 and we're left 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.

Advancing to step 11:
If we divide 6280 by 668, we get 9 and a remainder of 268.
Write down 9 as next digit of the result. 
Result so far: 80968.049
Deduct 6012 from 6280 and we're left 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.

Step 12:
668 can be fit into 2680 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 80968.0494
If we take 2672 away from 2680, we end up 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.

Let's proceed to step 13:
80 divided by 668 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 80968.0494
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
668 can be fit into 800 1 times, resulting in a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 80968.049401
Subtracting 668 from 800 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 15:
The number 668 fits into 1320 1 times, leaving a remainder of 652.
Write down 1 as next digit of the result. 
Result so far: 80968.0494011
Subtract 668 from 1320 to get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

The final outcome is 80968.0494011, with a leftover of 6.52e-06.
