921993 ÷ 54 
We want to divide 921993 by 54.

On to step 1:
9 divided by 54 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 54

Advancing to step 2:
92 divided by 54 is 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 54 away from 92, we end up with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 54

Advancing to step 3:
When dividing 381 by 54, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 378 away from 381, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 54

Going ahead to step 4:
The number 54 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 170.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 54

Let's proceed to step 5:
The number 54 fits into 399 7 times, leaving a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 1707.0
If we take 378 away from 399, we end up with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 54

Step 6:
The number 54 fits into 213 3 times, leaving a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 17073.0
Subtracting 162 from 213 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
If we divide 510 by 54, we get 9 and a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 17073.9
If we take 486 away from 510, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
54 goes into 240 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 17073.94
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
54 can be fit into 240 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 17073.944
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 17073.944 and a remainder of 0.0024.
