We're dividing 55637237 by 639 
Let's see how many times 639 fits into 55637237.

Step 1:
639 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 639

Advancing to step 2:
639 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (6) from the dividend, attach it to 55 and continue: 556 / 639

Step 3:
639 can be fit into 556 0 times, resulting in a remainder of 556.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 556 after subtracting 0 from 556.
Bring next digit (3) of the dividend behind the 556 and repeat the process: 5563 / 639

Step 4:
If we divide 5563 by 639, we get 8 and a remainder of 451.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 5112 from 5563 leaves us with 451.
Include the next digit (7) from the dividend after 451, then repeat: 4517 / 639

On to step 5:
The number 639 fits into 4517 7 times, leaving a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtract 4473 from 4517 to get 44.
Include the next digit (2) from the dividend after 44, then repeat: 442 / 639

Going ahead to step 6:
639 can be fit into 442 0 times, resulting in a remainder of 442.
Record the quotient 0 as the next digit in the result. 
Result so far: 870.0
Deduct 0 from 442 and we're left with 442.
Fetch the next digit (3) from the dividend, attach it to 442 and continue: 4423 / 639

On to step 7:
4423 divided by 639 is 6 with a remainder of 589.
Record the quotient 6 as the next digit in the result. 
Result so far: 8706.0
If we subtract 3834 from 4423, we get 589.
Grab the next digit (7) from the dividend, add it to 589, then carry on: 5897 / 639

Moving on to step 8:
When dividing 5897 by 639, we get 9 with a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 87069.0
Subtracting 5751 from 5897 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 9:
If we divide 1460 by 639, we get 2 and a remainder of 182.
The next digit of our result is 2. 
Result so far: 87069.2
Subtract 1278 from 1460 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 10:
When dividing 1820 by 639, we get 2 with a remainder of 542.
Put 2 as the next digit of the answer. 
Result so far: 87069.22
Subtract 1278 from 1820 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

In conclusion, the division gives 87069.22 with a balance of 0.542.
