We're dividing 321687 by 54 
We want to divide 321687 by 54.

Advancing to step 1:
If we divide 3 by 54, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 54

Going ahead to step 2:
54 goes into 32 0 times with a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 54

On to step 3:
If we divide 321 by 54, we get 5 and a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 51 after subtracting 270 from 321.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 54

Let's proceed to step 4:
516 divided by 54 is 9 with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 59.0
If we subtract 486 from 516, we get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 54

Advancing to step 5:
When dividing 308 by 54, we get 5 with a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 595.0
Deduct 270 from 308 and we're left with 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 54

On to step 6:
54 goes into 387 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 5957.0
Subtracting 378 from 387 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 54, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 5957.1
Deduct 54 from 90 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
54 can be fit into 360 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 5957.16
Subtract 324 from 360 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
When dividing 360 by 54, we get 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 5957.166
If we take 324 away from 360, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 5957.166, and the remainder is 0.0036.
