521658 divided by 68 
We're looking to find how many times 68 goes into 521658.

Step 1:
When dividing 5 by 68, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 68

Step 2:
68 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 68

Let's proceed to step 3:
68 goes into 521 7 times with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 45 after subtracting 476 from 521.
Include the next digit (6) from the dividend after 45, then repeat: 456 / 68

Step 4:
456 divided by 68 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 408 from 456 to get 48.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 68

On to step 5:
When dividing 485 by 68, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 767.0
The remainder is 9 after subtracting 476 from 485.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 68

Step 6:
68 goes into 98 1 times with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 7671.0
The remainder is 30 after subtracting 68 from 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
If we divide 300 by 68, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 7671.4
Deduct 272 from 300 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
280 divided by 68 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 7671.44
Subtracting 272 from 280 leaves us 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.

The final outcome is 7671.44, with a leftover of 0.008.
