18072155 divided by 639 
We want to divide 18072155 by 639.

Going ahead to step 1:
639 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 639

Step 2:
When dividing 18 by 639, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 639

Advancing to step 3:
639 can be fit into 180 0 times, resulting in a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 180 leaves us with 180.
Include the next digit (7) from the dividend after 180, then repeat: 1807 / 639

On to step 4:
639 can be fit into 1807 2 times, resulting in a remainder of 529.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1278 from 1807 and we're left with 529.
Bring next digit (2) of the dividend behind the 529 and repeat the process: 5292 / 639

Step 5:
639 goes into 5292 8 times with a remainder of 180.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 5112 from 5292 and we're left with 180.
Include the next digit (1) from the dividend after 180, then repeat: 1801 / 639

Advancing to step 6:
The number 639 fits into 1801 2 times, leaving a remainder of 523.
Record the quotient 2 as the next digit in the result. 
Result so far: 282.0
If we subtract 1278 from 1801, we get 523.
Include the next digit (5) from the dividend after 523, then repeat: 5235 / 639

On to step 7:
If we divide 5235 by 639, we get 8 and a remainder of 123.
Use 8 as the next digit of our solution. 
Result so far: 2828.0
If we take 5112 away from 5235, we end up with 123.
Take the next digit (5) from the dividend and append it to 123, then repeat: 1235 / 639

On to step 8:
639 can be fit into 1235 1 times, resulting in a remainder of 596.
Record the quotient 1 as the next digit in the result. 
Result so far: 28281.0
Subtract 639 from 1235 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 9:
If we divide 5960 by 639, we get 9 and a remainder of 209.
The number 9 becomes the next digit in our result. 
Result so far: 28281.9
If we take 5751 away from 5960, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 10:
639 goes into 2090 3 times with a remainder of 173.
Record the quotient 3 as the next digit in the result. 
Result so far: 28281.93
Subtract 1917 from 2090 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 11:
The number 639 fits into 1730 2 times, leaving a remainder of 452.
The next digit of our result is 2. 
Result so far: 28281.932
Subtract 1278 from 1730 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 12:
When dividing 4520 by 639, we get 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 28281.9327
The remainder is 47 after subtracting 4473 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 13:
639 goes into 470 0 times with a remainder of 470.
The next digit of our result is 0. 
Result so far: 28281.9327
Subtracting 0 from 470 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 14:
The number 639 fits into 4700 7 times, leaving a remainder of 227.
Write down 7 as next digit of the result. 
Result so far: 28281.932707
If we subtract 4473 from 4700, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 15:
639 can be fit into 2270 3 times, resulting in a remainder of 353.
The next digit of our result is 3. 
Result so far: 28281.9327073
The remainder is 353 after subtracting 1917 from 2270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 16:
639 can be fit into 3530 5 times, resulting in a remainder of 335.
The next digit of our result is 5. 
Result so far: 28281.93270735
If we subtract 3195 from 3530, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The quotient of the division is 28281.93270735, and the remainder is 3.35e-07.
