We're dividing 506891 by 15 
We're looking to find how many times 15 goes into 506891.

On to step 1:
If we divide 5 by 15, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 15

On to step 2:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 45 from 50 leaves us with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 15

Going ahead to step 3:
If we divide 56 by 15, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 33.0
Subtracting 45 from 56 leaves us with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 15

On to step 4:
If we divide 118 by 15, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 337.0
The remainder is 13 after subtracting 105 from 118.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 15

Going ahead to step 5:
15 goes into 139 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 3379.0
Subtracting 135 from 139 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 15

Going ahead to step 6:
When dividing 41 by 15, we get 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 33792.0
If we subtract 30 from 41, we 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.

Moving on to step 7:
When dividing 110 by 15, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 33792.7
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 33792.73
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
15 goes into 50 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 33792.733
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 33792.733, and the remainder is 0.0005.
