Let's divide 516821 by 36
We want to divide 516821 by 36.

Step 1:
5 divided by 36 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.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 36

On to step 2:
51 divided by 36 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 15 after subtracting 36 from 51.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 36

Advancing to step 3:
When dividing 156 by 36, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 144 from 156 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 36

Step 4:
36 goes into 128 3 times with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
Subtracting 108 from 128 leaves us with 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 36

Advancing to step 5:
When dividing 202 by 36, we get 5 with a remainder of 22.
The next digit of our result is 5. 
Result so far: 1435.0
If we take 180 away from 202, we end up with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 36

Moving on to step 6:
221 divided by 36 is 6 with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 14356.0
If we take 216 away from 221, we end up 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.

Going ahead to step 7:
36 can be fit into 50 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 14356.1
The remainder is 14 after subtracting 36 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
If we divide 140 by 36, we get 3 and a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 14356.13
If we subtract 108 from 140, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
36 can be fit into 320 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 14356.138
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
36 can be fit into 320 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 14356.1388
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 14356.1388, and the remainder is 0.00032.
