We're dividing 52678499 by 639 
We want to divide 52678499 by 639.

Let's proceed to step 1:
If we divide 5 by 639, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 639

Advancing to step 2:
The number 639 fits into 52 0 times, leaving a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Bring next digit (6) of the dividend behind the 52 and repeat the process: 526 / 639

Advancing to step 3:
The number 639 fits into 526 0 times, leaving a remainder of 526.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 526 to get 526.
Append the next digit (7) from the dividend to 526 and continue with: 5267 / 639

Let's proceed to step 4:
When dividing 5267 by 639, we get 8 with a remainder of 155.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 5112 from 5267 and we're left with 155.
Take the next digit (8) from the dividend and append it to 155, then repeat: 1558 / 639

Advancing to step 5:
639 goes into 1558 2 times with a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
If we subtract 1278 from 1558, we get 280.
Bring next digit (4) of the dividend behind the 280 and repeat the process: 2804 / 639

Advancing to step 6:
2804 divided by 639 is 4 with a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 824.0
Subtracting 2556 from 2804 leaves us with 248.
Bring next digit (9) of the dividend behind the 248 and repeat the process: 2489 / 639

Advancing to step 7:
If we divide 2489 by 639, we get 3 and a remainder of 572.
Put 3 as the next digit of the answer. 
Result so far: 8243.0
Subtract 1917 from 2489 to get 572.
Include the next digit (9) from the dividend after 572, then repeat: 5729 / 639

Let's proceed to step 8:
639 can be fit into 5729 8 times, resulting in a remainder of 617.
The number 8 becomes the next digit in our result. 
Result so far: 82438.0
If we take 5112 away from 5729, we end up with 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Advancing to step 9:
639 goes into 6170 9 times with a remainder of 419.
The next digit of our result is 9. 
Result so far: 82438.9
If we subtract 5751 from 6170, we get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Advancing to step 10:
639 can be fit into 4190 6 times, resulting in a remainder of 356.
Record the quotient 6 as the next digit in the result. 
Result so far: 82438.96
Subtract 3834 from 4190 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 11:
When dividing 3560 by 639, we get 5 with a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 82438.965
The remainder is 365 after subtracting 3195 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 12:
The number 639 fits into 3650 5 times, leaving a remainder of 455.
Put 5 as the next digit of the answer. 
Result so far: 82438.9655
Subtracting 3195 from 3650 leaves us with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Our division results in 82438.9655 with a remaining 0.00455.
