68338316 ÷ 521 
We want to figure out the number of times 68338316 can be divided by 521.

On to step 1:
521 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 521

Going ahead to step 2:
68 divided by 521 is 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Take the next digit (3) from the dividend and append it to 68, then repeat: 683 / 521

Step 3:
521 can be fit into 683 1 times, resulting in a remainder of 162.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 521 from 683 and we're left with 162.
Bring next digit (3) of the dividend behind the 162 and repeat the process: 1623 / 521

Step 4:
1623 divided by 521 is 3 with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 1563 from 1623 to get 60.
Grab the next digit (8) from the dividend, add it to 60, then carry on: 608 / 521

Let's proceed to step 5:
When dividing 608 by 521, we get 1 with a remainder of 87.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Subtracting 521 from 608 leaves us with 87.
Take the next digit (3) from the dividend and append it to 87, then repeat: 873 / 521

Let's proceed to step 6:
521 can be fit into 873 1 times, resulting in a remainder of 352.
The number 1 becomes the next digit in our result. 
Result so far: 1311.0
If we take 521 away from 873, we end up with 352.
Include the next digit (1) from the dividend after 352, then repeat: 3521 / 521

On to step 7:
If we divide 3521 by 521, we get 6 and a remainder of 395.
Write down 6 as next digit of the result. 
Result so far: 13116.0
The remainder is 395 after subtracting 3126 from 3521.
Bring next digit (6) of the dividend behind the 395 and repeat the process: 3956 / 521

Let's proceed to step 8:
521 can be fit into 3956 7 times, resulting in a remainder of 309.
Write down 7 as next digit of the result. 
Result so far: 131167.0
Subtracting 3647 from 3956 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 9:
If we divide 3090 by 521, we get 5 and a remainder of 485.
Use 5 as the next digit of our solution. 
Result so far: 131167.5
The remainder is 485 after subtracting 2605 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Moving on to step 10:
When dividing 4850 by 521, we get 9 with a remainder of 161.
The number 9 becomes the next digit in our result. 
Result so far: 131167.59
Subtracting 4689 from 4850 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Let's proceed to step 11:
The number 521 fits into 1610 3 times, leaving a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 131167.593
If we subtract 1563 from 1610, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 12:
521 can be fit into 470 0 times, resulting in a remainder of 470.
Write down 0 as next digit of the result. 
Result so far: 131167.593
Subtracting 0 from 470 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 13:
521 goes into 4700 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 131167.59309
Subtract 4689 from 4700 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
When dividing 110 by 521, we get 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 131167.59309
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 15:
The number 521 fits into 1100 2 times, leaving a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 131167.5930902
Subtract 1042 from 1100 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 16:
521 goes into 580 1 times with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 131167.59309021
If we subtract 521 from 580, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final outcome is 131167.59309021, with a leftover of 5.9e-08.
