We divide 17678709 by 839
We want to divide 17678709 by 839.

Going ahead to step 1:
839 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 839

Moving on to step 2:
839 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 839

On to step 3:
839 goes into 176 0 times with a remainder of 176.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 176 leaves us with 176.
Grab the next digit (7) from the dividend, add it to 176, then carry on: 1767 / 839

Let's proceed to step 4:
1767 divided by 839 is 2 with a remainder of 89.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1678 from 1767 and we're left with 89.
Grab the next digit (8) from the dividend, add it to 89, then carry on: 898 / 839

Let's proceed to step 5:
If we divide 898 by 839, we get 1 and a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 839 from 898 leaves us with 59.
Grab the next digit (7) from the dividend, add it to 59, then carry on: 597 / 839

Step 6:
The number 839 fits into 597 0 times, leaving a remainder of 597.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
If we take 0 away from 597, we end up with 597.
Take the next digit (0) from the dividend and append it to 597, then repeat: 5970 / 839

Step 7:
When dividing 5970 by 839, we get 7 with a remainder of 97.
Record the quotient 7 as the next digit in the result. 
Result so far: 2107.0
If we take 5873 away from 5970, we end up with 97.
Fetch the next digit (9) from the dividend, attach it to 97 and continue: 979 / 839

Advancing to step 8:
When dividing 979 by 839, we get 1 with a remainder of 140.
Use 1 as the next digit of our solution. 
Result so far: 21071.0
If we take 839 away from 979, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 9:
839 goes into 1400 1 times with a remainder of 561.
Write down 1 as next digit of the result. 
Result so far: 21071.1
Subtracting 839 from 1400 leaves us with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Going ahead to step 10:
When dividing 5610 by 839, we get 6 with a remainder of 576.
Write down 6 as next digit of the result. 
Result so far: 21071.16
Subtract 5034 from 5610 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 11:
When dividing 5760 by 839, we get 6 with a remainder of 726.
Use 6 as the next digit of our solution. 
Result so far: 21071.166
The remainder is 726 after subtracting 5034 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

The final result is 21071.166 with a remainder of 0.0726.
