Let's divide 78921 by 54
We want to figure out the number of times 78921 can be divided by 54.

Going ahead to step 1:
When dividing 7 by 54, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 54

Moving on to step 2:
If we divide 78 by 54, we get 1 and a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 54 from 78 to get 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 54

Going ahead to step 3:
The number 54 fits into 249 4 times, leaving a remainder of 33.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 216 from 249, we get 33.
Include the next digit (2) from the dividend after 33, then repeat: 332 / 54

Step 4:
54 can be fit into 332 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 146.0
Deduct 324 from 332 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 54

On to step 5:
If we divide 81 by 54, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 1461.0
If we take 54 away from 81, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 6:
The number 54 fits into 270 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 1461.5
Subtracting 270 from 270 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.

Advancing to step 7:
54 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1461.5
If we subtract 0 from 0, we get 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 54 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1461.5
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 1461.5, and the remainder is 0.0.
