56158219 ÷ 639 
Our goal is to divide 56158219 by 639.

Advancing to step 1:
639 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 639

Going ahead to step 2:
639 goes into 56 0 times with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 639

Let's proceed to step 3:
When dividing 561 by 639, we get 0 with a remainder of 561.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 561, we get 561.
Take the next digit (5) from the dividend and append it to 561, then repeat: 5615 / 639

Let's proceed to step 4:
5615 divided by 639 is 8 with a remainder of 503.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 5112 from 5615 and we're left with 503.
Bring next digit (8) of the dividend behind the 503 and repeat the process: 5038 / 639

Let's proceed to step 5:
When dividing 5038 by 639, we get 7 with a remainder of 565.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we take 4473 away from 5038, we end up with 565.
Fetch the next digit (2) from the dividend, attach it to 565 and continue: 5652 / 639

Step 6:
639 goes into 5652 8 times with a remainder of 540.
Write down 8 as next digit of the result. 
Result so far: 878.0
Deduct 5112 from 5652 and we're left with 540.
Grab the next digit (1) from the dividend, add it to 540, then carry on: 5401 / 639

Moving on to step 7:
If we divide 5401 by 639, we get 8 and a remainder of 289.
Put 8 as the next digit of the answer. 
Result so far: 8788.0
Subtract 5112 from 5401 to get 289.
Take the next digit (9) from the dividend and append it to 289, then repeat: 2899 / 639

Step 8:
639 goes into 2899 4 times with a remainder of 343.
The number 4 becomes the next digit in our result. 
Result so far: 87884.0
The remainder is 343 after subtracting 2556 from 2899.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 9:
If we divide 3430 by 639, we get 5 and a remainder of 235.
The next digit of our result is 5. 
Result so far: 87884.5
Subtract 3195 from 3430 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 10:
If we divide 2350 by 639, we get 3 and a remainder of 433.
The number 3 becomes the next digit in our result. 
Result so far: 87884.53
If we take 1917 away from 2350, we end up with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

On to step 11:
639 goes into 4330 6 times with a remainder of 496.
Write down 6 as next digit of the result. 
Result so far: 87884.536
Subtracting 3834 from 4330 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 12:
The number 639 fits into 4960 7 times, leaving a remainder of 487.
The number 7 becomes the next digit in our result. 
Result so far: 87884.5367
Subtracting 4473 from 4960 leaves us with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

On to step 13:
The number 639 fits into 4870 7 times, leaving a remainder of 397.
The number 7 becomes the next digit in our result. 
Result so far: 87884.53677
If we take 4473 away from 4870, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

In conclusion, the division gives 87884.53677 with a balance of 0.000397.
