521874 ÷ 10 
Our goal is to divide 521874 by 10.

Advancing to step 1:
5 divided by 10 is 0 with 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.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 10

Moving on to step 2:
The number 10 fits into 52 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 50 away from 52, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 10

Advancing to step 3:
21 divided by 10 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Deduct 20 from 21 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 10

Step 4:
When dividing 18 by 10, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 521.0
Subtracting 10 from 18 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 10

Moving on to step 5:
10 goes into 87 8 times with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 5218.0
Subtract 80 from 87 to get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 10

Step 6:
10 goes into 74 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 52187.0
The remainder is 4 after subtracting 70 from 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 10 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 52187.4
If we take 40 away from 40, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 10 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 52187.4
Subtracting 0 from 0 leaves us with 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 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 52187.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 52187.4, and the remainder is 0.0.
