We look at the division of 12024913 by 839 
We want to figure out the number of times 12024913 can be divided by 839.

Step 1:
If we divide 1 by 839, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 839

Going ahead to step 2:
12 divided by 839 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 839

Advancing to step 3:
If we divide 120 by 839, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 120 after subtracting 0 from 120.
Fetch the next digit (2) from the dividend, attach it to 120 and continue: 1202 / 839

Advancing to step 4:
1202 divided by 839 is 1 with a remainder of 363.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 839 from 1202 to get 363.
Append the next digit (4) from the dividend to 363 and continue with: 3634 / 839

On to step 5:
839 goes into 3634 4 times with a remainder of 278.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 3356 from 3634 and we're left with 278.
Append the next digit (9) from the dividend to 278 and continue with: 2789 / 839

Advancing to step 6:
If we divide 2789 by 839, we get 3 and a remainder of 272.
The next digit of our result is 3. 
Result so far: 143.0
The remainder is 272 after subtracting 2517 from 2789.
Grab the next digit (1) from the dividend, add it to 272, then carry on: 2721 / 839

Let's proceed to step 7:
839 can be fit into 2721 3 times, resulting in a remainder of 204.
The number 3 becomes the next digit in our result. 
Result so far: 1433.0
If we take 2517 away from 2721, we end up with 204.
Grab the next digit (3) from the dividend, add it to 204, then carry on: 2043 / 839

Step 8:
The number 839 fits into 2043 2 times, leaving a remainder of 365.
Put 2 as the next digit of the answer. 
Result so far: 14332.0
If we take 1678 away from 2043, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 9:
If we divide 3650 by 839, we get 4 and a remainder of 294.
Record the quotient 4 as the next digit in the result. 
Result so far: 14332.4
If we take 3356 away from 3650, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 10:
The number 839 fits into 2940 3 times, leaving a remainder of 423.
Record the quotient 3 as the next digit in the result. 
Result so far: 14332.43
Subtracting 2517 from 2940 leaves us with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

On to step 11:
4230 divided by 839 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 14332.435
If we take 4195 away from 4230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
The number 839 fits into 350 0 times, leaving a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 14332.435
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 13:
839 goes into 3500 4 times with a remainder of 144.
The next digit of our result is 4. 
Result so far: 14332.43504
If we subtract 3356 from 3500, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 14:
If we divide 1440 by 839, we get 1 and a remainder of 601.
Record the quotient 1 as the next digit in the result. 
Result so far: 14332.435041
Deduct 839 from 1440 and we're left with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Advancing to step 15:
839 can be fit into 6010 7 times, resulting in a remainder of 137.
The number 7 becomes the next digit in our result. 
Result so far: 14332.4350417
Subtract 5873 from 6010 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 16:
When dividing 1370 by 839, we get 1 with a remainder of 531.
Write down 1 as next digit of the result. 
Result so far: 14332.43504171
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.

After the division, we end up with 14332.43504171 and a remainder of 5.31e-07.
