We look at the division of 15689809 by 839 
Our goal is to divide 15689809 by 839.

Step 1:
If we divide 1 by 839, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 839

Moving on to step 2:
839 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 839

Going ahead to step 3:
156 divided by 839 is 0 with a remainder of 156.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 156 after subtracting 0 from 156.
Bring next digit (8) of the dividend behind the 156 and repeat the process: 1568 / 839

Step 4:
839 can be fit into 1568 1 times, resulting in a remainder of 729.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 839 from 1568, we get 729.
Bring next digit (9) of the dividend behind the 729 and repeat the process: 7299 / 839

Moving on to step 5:
If we divide 7299 by 839, we get 8 and a remainder of 587.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 587 after subtracting 6712 from 7299.
Append the next digit (8) from the dividend to 587 and continue with: 5878 / 839

Advancing to step 6:
5878 divided by 839 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 187.0
Subtracting 5873 from 5878 leaves us with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 839

Moving on to step 7:
50 divided by 839 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 1870.0
If we take 0 away from 50, we end up with 50.
Bring next digit (9) of the dividend behind the 50 and repeat the process: 509 / 839

Going ahead to step 8:
When dividing 509 by 839, we get 0 with a remainder of 509.
The next digit of our result is 0. 
Result so far: 18700.0
Deduct 0 from 509 and we're left with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Step 9:
5090 divided by 839 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 18700.6
Subtract 5034 from 5090 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
839 can be fit into 560 0 times, resulting in a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 18700.6
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 11:
5600 divided by 839 is 6 with a remainder of 566.
Record the quotient 6 as the next digit in the result. 
Result so far: 18700.606
If we take 5034 away from 5600, we end up with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Going ahead to step 12:
839 goes into 5660 6 times with a remainder of 626.
Put 6 as the next digit of the answer. 
Result so far: 18700.6066
The remainder is 626 after subtracting 5034 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Our division results in 18700.6066 with a remaining 0.00626.
