68451537 ÷ 510 
We want to figure out the number of times 68451537 can be divided by 510.

Let's proceed to step 1:
510 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 510

Step 2:
When dividing 68 by 510, we get 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 510

On to step 3:
684 divided by 510 is 1 with a remainder of 174.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 174 after subtracting 510 from 684.
Take the next digit (5) from the dividend and append it to 174, then repeat: 1745 / 510

Going ahead to step 4:
510 can be fit into 1745 3 times, resulting in a remainder of 215.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 1530 from 1745 and we're left with 215.
Grab the next digit (1) from the dividend, add it to 215, then carry on: 2151 / 510

Let's proceed to step 5:
When dividing 2151 by 510, we get 4 with a remainder of 111.
Use 4 as the next digit of our solution. 
Result so far: 134.0
The remainder is 111 after subtracting 2040 from 2151.
Fetch the next digit (5) from the dividend, attach it to 111 and continue: 1115 / 510

Step 6:
The number 510 fits into 1115 2 times, leaving a remainder of 95.
Write down 2 as next digit of the result. 
Result so far: 1342.0
Deduct 1020 from 1115 and we're left with 95.
Bring next digit (3) of the dividend behind the 95 and repeat the process: 953 / 510

Advancing to step 7:
510 can be fit into 953 1 times, resulting in a remainder of 443.
Write down 1 as next digit of the result. 
Result so far: 13421.0
The remainder is 443 after subtracting 510 from 953.
Fetch the next digit (7) from the dividend, attach it to 443 and continue: 4437 / 510

On to step 8:
4437 divided by 510 is 8 with a remainder of 357.
Record the quotient 8 as the next digit in the result. 
Result so far: 134218.0
Subtract 4080 from 4437 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Let's proceed to step 9:
When dividing 3570 by 510, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 134218.7
Subtract 3570 from 3570 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 510, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 134218.7
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
When dividing 0 by 510, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 134218.7
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 134218.7 and a remainder of 0.0.
