We look at the division of 486121 by 54 
We want to divide 486121 by 54.

On to step 1:
When dividing 4 by 54, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 54

Advancing to step 2:
54 can be fit into 48 0 times, resulting in a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 54

Moving on to step 3:
If we divide 486 by 54, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 486 from 486 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 54

Going ahead to step 4:
54 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 90.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 54

Let's proceed to step 5:
12 divided by 54 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 900.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 54

On to step 6:
121 divided by 54 is 2 with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 9002.0
The remainder is 13 after subtracting 108 from 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
When dividing 130 by 54, we get 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 9002.2
If we subtract 108 from 130, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
54 can be fit into 220 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 9002.24
If we take 216 away from 220, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
54 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9002.24
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
The number 54 fits into 400 7 times, leaving a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 9002.2407
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
If we divide 220 by 54, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 9002.24074
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
54 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 9002.24074
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
54 goes into 400 7 times with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 9002.2407407
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
220 divided by 54 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 9002.24074074
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 9002.24074074 with a balance of 4e-09.
