521975 ÷ 6 
We want to figure out the number of times 521975 can be divided by 6.

Moving on to step 1:
If we divide 5 by 6, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 6

Advancing to step 2:
If we divide 52 by 6, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 48 from 52 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 6

Advancing to step 3:
41 divided by 6 is 6 with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtract 36 from 41 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 6

Step 4:
6 goes into 59 9 times with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 869.0
Subtracting 54 from 59 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 6

Let's proceed to step 5:
6 goes into 57 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 8699.0
If we subtract 54 from 57, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 6

Let's proceed to step 6:
The number 6 fits into 35 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 86995.0
Subtract 30 from 35 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.

Step 7:
6 can be fit into 50 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 86995.8
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 6 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 86995.83
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 6, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 86995.833
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 86995.833 with a remaining 0.0002.
