We're dividing 54763623 by 639 
Our goal is to divide 54763623 by 639.

Advancing to step 1:
639 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 639

Moving on to step 2:
639 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 639

Moving on to step 3:
639 goes into 547 0 times with a remainder of 547.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 547 to get 547.
Fetch the next digit (6) from the dividend, attach it to 547 and continue: 5476 / 639

Going ahead to step 4:
The number 639 fits into 5476 8 times, leaving a remainder of 364.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 364 after subtracting 5112 from 5476.
Append the next digit (3) from the dividend to 364 and continue with: 3643 / 639

Let's proceed to step 5:
639 can be fit into 3643 5 times, resulting in a remainder of 448.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtracting 3195 from 3643 leaves us with 448.
Take the next digit (6) from the dividend and append it to 448, then repeat: 4486 / 639

Step 6:
The number 639 fits into 4486 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 857.0
If we take 4473 away from 4486, we end up with 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 639

Step 7:
If we divide 132 by 639, we get 0 and a remainder of 132.
Record the quotient 0 as the next digit in the result. 
Result so far: 8570.0
If we subtract 0 from 132, we get 132.
Include the next digit (3) from the dividend after 132, then repeat: 1323 / 639

Step 8:
If we divide 1323 by 639, we get 2 and a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 85702.0
If we take 1278 away from 1323, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
639 can be fit into 450 0 times, resulting in a remainder of 450.
Record the quotient 0 as the next digit in the result. 
Result so far: 85702.0
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 10:
The number 639 fits into 4500 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 85702.07
Subtracting 4473 from 4500 leaves us 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.

Moving on to step 11:
When dividing 270 by 639, we get 0 with a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 85702.07
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 12:
639 goes into 2700 4 times with a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 85702.0704
If we take 2556 away from 2700, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 13:
The number 639 fits into 1440 2 times, leaving a remainder of 162.
Write down 2 as next digit of the result. 
Result so far: 85702.07042
The remainder is 162 after subtracting 1278 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 14:
1620 divided by 639 is 2 with a remainder of 342.
Put 2 as the next digit of the answer. 
Result so far: 85702.070422
If we subtract 1278 from 1620, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The final outcome is 85702.070422, with a leftover of 3.42e-05.
