We divide 431397 by 54
Let's see how many times 54 fits into 431397.

On to step 1:
The number 54 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 54

Going ahead to step 2:
54 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 54

Advancing to step 3:
The number 54 fits into 431 7 times, leaving a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 378 away from 431, we end up with 53.
Grab the next digit (3) from the dividend, add it to 53, then carry on: 533 / 54

Let's proceed to step 4:
If we divide 533 by 54, we get 9 and a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtracting 486 from 533 leaves us with 47.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 54

Step 5:
When dividing 479 by 54, we get 8 with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 798.0
If we take 432 away from 479, we end up with 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 54

On to step 6:
If we divide 477 by 54, we get 8 and a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 7988.0
Deduct 432 from 477 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 7:
When dividing 450 by 54, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 7988.8
Deduct 432 from 450 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
54 goes into 180 3 times with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 7988.83
If we subtract 162 from 180, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
If we divide 180 by 54, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 7988.833
Subtracting 162 from 180 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 7988.833 with a remaining 0.0018.
