35123944 ÷ 839 
The aim is to understand the frequency of 839 in 35123944.

On to step 1:
When dividing 3 by 839, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 839

Moving on to step 2:
When dividing 35 by 839, we get 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 839

On to step 3:
If we divide 351 by 839, we get 0 and a remainder of 351.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 351, we end up with 351.
Append the next digit (2) from the dividend to 351 and continue with: 3512 / 839

Moving on to step 4:
3512 divided by 839 is 4 with a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 3356 from 3512 to get 156.
Append the next digit (3) from the dividend to 156 and continue with: 1563 / 839

Let's proceed to step 5:
839 can be fit into 1563 1 times, resulting in a remainder of 724.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 839 from 1563 leaves us with 724.
Include the next digit (9) from the dividend after 724, then repeat: 7249 / 839

Moving on to step 6:
When dividing 7249 by 839, we get 8 with a remainder of 537.
The number 8 becomes the next digit in our result. 
Result so far: 418.0
If we take 6712 away from 7249, we end up with 537.
Take the next digit (4) from the dividend and append it to 537, then repeat: 5374 / 839

Let's proceed to step 7:
839 goes into 5374 6 times with a remainder of 340.
The number 6 becomes the next digit in our result. 
Result so far: 4186.0
Subtract 5034 from 5374 to get 340.
Grab the next digit (4) from the dividend, add it to 340, then carry on: 3404 / 839

Going ahead to step 8:
3404 divided by 839 is 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 41864.0
Deduct 3356 from 3404 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
480 divided by 839 is 0 with a remainder of 480.
The next digit of our result is 0. 
Result so far: 41864.0
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 10:
4800 divided by 839 is 5 with a remainder of 605.
Use 5 as the next digit of our solution. 
Result so far: 41864.05
If we take 4195 away from 4800, we end up with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Going ahead to step 11:
The number 839 fits into 6050 7 times, leaving a remainder of 177.
Use 7 as the next digit of our solution. 
Result so far: 41864.057
If we subtract 5873 from 6050, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 12:
When dividing 1770 by 839, we get 2 with a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 41864.0572
The remainder is 92 after subtracting 1678 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 13:
920 divided by 839 is 1 with a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 41864.05721
Subtract 839 from 920 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 14:
839 goes into 810 0 times with a remainder of 810.
Put 0 as the next digit of the answer. 
Result so far: 41864.05721
If we subtract 0 from 810, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Moving on to step 15:
8100 divided by 839 is 9 with a remainder of 549.
Put 9 as the next digit of the answer. 
Result so far: 41864.0572109
Subtract 7551 from 8100 to get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Step 16:
839 goes into 5490 6 times with a remainder of 456.
The next digit of our result is 6. 
Result so far: 41864.05721096
If we take 5034 away from 5490, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Our division results in 41864.05721096 with a remaining 4.56e-07.
