We divide 65531210 by 391
We want to figure out the number of times 65531210 can be divided by 391.

On to step 1:
391 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 391

On to step 2:
When dividing 65 by 391, we get 0 with a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Include the next digit (5) from the dividend after 65, then repeat: 655 / 391

Step 3:
391 goes into 655 1 times with a remainder of 264.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 264 after subtracting 391 from 655.
Fetch the next digit (3) from the dividend, attach it to 264 and continue: 2643 / 391

Moving on to step 4:
The number 391 fits into 2643 6 times, leaving a remainder of 297.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 2346 from 2643 and we're left with 297.
Include the next digit (1) from the dividend after 297, then repeat: 2971 / 391

Advancing to step 5:
391 goes into 2971 7 times with a remainder of 234.
Use 7 as the next digit of our solution. 
Result so far: 167.0
If we take 2737 away from 2971, we end up with 234.
Grab the next digit (2) from the dividend, add it to 234, then carry on: 2342 / 391

Advancing to step 6:
If we divide 2342 by 391, we get 5 and a remainder of 387.
Use 5 as the next digit of our solution. 
Result so far: 1675.0
If we subtract 1955 from 2342, we get 387.
Take the next digit (1) from the dividend and append it to 387, then repeat: 3871 / 391

On to step 7:
If we divide 3871 by 391, we get 9 and a remainder of 352.
Write down 9 as next digit of the result. 
Result so far: 16759.0
If we take 3519 away from 3871, we end up with 352.
Bring next digit (0) of the dividend behind the 352 and repeat the process: 3520 / 391

Let's proceed to step 8:
3520 divided by 391 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 167599.0
Deduct 3519 from 3520 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 391, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 167599.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
100 divided by 391 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 167599.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 167599.0, and the remainder is 0.1.
