63879969 ÷ 54 
Let's see how many times 54 fits into 63879969.

Advancing to step 1:
When dividing 6 by 54, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 54

Moving on to step 2:
63 divided by 54 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 54 from 63 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 54

Let's proceed to step 3:
98 divided by 54 is 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 54 from 98 and we're left with 44.
Append the next digit (7) from the dividend to 44 and continue with: 447 / 54

Going ahead to step 4:
The number 54 fits into 447 8 times, leaving a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 118.0
If we subtract 432 from 447, we get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 54

Moving on to step 5:
When dividing 159 by 54, we get 2 with a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 1182.0
Subtracting 108 from 159 leaves us with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 54

Step 6:
If we divide 519 by 54, we get 9 and a remainder of 33.
The next digit of our result is 9. 
Result so far: 11829.0
If we subtract 486 from 519, we get 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 54

On to step 7:
The number 54 fits into 336 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 118296.0
If we take 324 away from 336, we end up with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 54

Advancing to step 8:
When dividing 129 by 54, we get 2 with a remainder of 21.
The next digit of our result is 2. 
Result so far: 1182962.0
The remainder is 21 after subtracting 108 from 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
54 can be fit into 210 3 times, resulting in a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 1182962.3
Deduct 162 from 210 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
The number 54 fits into 480 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 1182962.38
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
54 goes into 480 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 1182962.388
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 1182962.388 and a remainder of 0.0048.
