Let's divide 420485 by 54
We want to divide 420485 by 54.

Step 1:
54 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 54

Moving on to step 2:
42 divided by 54 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 54

Step 3:
The number 54 fits into 420 7 times, leaving a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 378 from 420 to get 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 54

Advancing to step 4:
54 can be fit into 424 7 times, resulting in a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtracting 378 from 424 leaves us with 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 54

Advancing to step 5:
The number 54 fits into 468 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 778.0
If we take 432 away from 468, we end up with 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 54

Moving on to step 6:
365 divided by 54 is 6 with a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 7786.0
Subtracting 324 from 365 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
If we divide 410 by 54, we get 7 and a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 7786.7
Subtract 378 from 410 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
The number 54 fits into 320 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 7786.75
If we subtract 270 from 320, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
54 can be fit into 500 9 times, resulting in a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 7786.759
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
If we divide 140 by 54, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 7786.7592
Subtract 108 from 140 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
320 divided by 54 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 7786.75925
Subtracting 270 from 320 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
54 can be fit into 500 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 7786.759259
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
140 divided by 54 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 7786.7592592
Subtracting 108 from 140 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
The number 54 fits into 320 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 7786.75925925
The remainder is 50 after subtracting 270 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 7786.75925925 with a balance of 5e-08.
