12518017 ÷ 839 
Let's see how many times 839 fits into 12518017.

Let's proceed to step 1:
The number 839 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 839

On to step 2:
If we divide 12 by 839, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 839

Step 3:
125 divided by 839 is 0 with a remainder of 125.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 125 to get 125.
Append the next digit (1) from the dividend to 125 and continue with: 1251 / 839

Going ahead to step 4:
When dividing 1251 by 839, we get 1 with a remainder of 412.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 839 from 1251 to get 412.
Append the next digit (8) from the dividend to 412 and continue with: 4128 / 839

On to step 5:
If we divide 4128 by 839, we get 4 and a remainder of 772.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 3356 from 4128 leaves us with 772.
Fetch the next digit (0) from the dividend, attach it to 772 and continue: 7720 / 839

Going ahead to step 6:
When dividing 7720 by 839, we get 9 with a remainder of 169.
Use 9 as the next digit of our solution. 
Result so far: 149.0
The remainder is 169 after subtracting 7551 from 7720.
Bring next digit (1) of the dividend behind the 169 and repeat the process: 1691 / 839

On to step 7:
When dividing 1691 by 839, we get 2 with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 1492.0
Subtract 1678 from 1691 to get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 839

Advancing to step 8:
137 divided by 839 is 0 with a remainder of 137.
The next digit of our result is 0. 
Result so far: 14920.0
The remainder is 137 after subtracting 0 from 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 9:
839 goes into 1370 1 times with a remainder of 531.
Use 1 as the next digit of our solution. 
Result so far: 14920.1
The remainder is 531 after subtracting 839 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 10:
839 can be fit into 5310 6 times, resulting in a remainder of 276.
Put 6 as the next digit of the answer. 
Result so far: 14920.16
Deduct 5034 from 5310 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 11:
If we divide 2760 by 839, we get 3 and a remainder of 243.
Write down 3 as next digit of the result. 
Result so far: 14920.163
If we subtract 2517 from 2760, we get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 12:
839 goes into 2430 2 times with a remainder of 752.
Record the quotient 2 as the next digit in the result. 
Result so far: 14920.1632
If we subtract 1678 from 2430, we get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Step 13:
If we divide 7520 by 839, we get 8 and a remainder of 808.
Use 8 as the next digit of our solution. 
Result so far: 14920.16328
If we take 6712 away from 7520, we end up with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

On to step 14:
If we divide 8080 by 839, we get 9 and a remainder of 529.
Record the quotient 9 as the next digit in the result. 
Result so far: 14920.163289
The remainder is 529 after subtracting 7551 from 8080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Advancing to step 15:
5290 divided by 839 is 6 with a remainder of 256.
Use 6 as the next digit of our solution. 
Result so far: 14920.1632896
Subtracting 5034 from 5290 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 16:
2560 divided by 839 is 3 with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 14920.16328963
The remainder is 43 after subtracting 2517 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 14920.16328963 and a remainder of 4.3e-08.
