Let's divide 67278911 by 839
The aim is to understand the frequency of 839 in 67278911.

Advancing to step 1:
If we divide 6 by 839, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 839

Moving on to step 2:
839 goes into 67 0 times with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Bring next digit (2) of the dividend behind the 67 and repeat the process: 672 / 839

On to step 3:
If we divide 672 by 839, we get 0 and a remainder of 672.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 672 leaves us with 672.
Append the next digit (7) from the dividend to 672 and continue with: 6727 / 839

On to step 4:
839 can be fit into 6727 8 times, resulting in a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 6712 from 6727, we get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 839

On to step 5:
The number 839 fits into 158 0 times, leaving a remainder of 158.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtracting 0 from 158 leaves us with 158.
Take the next digit (9) from the dividend and append it to 158, then repeat: 1589 / 839

Let's proceed to step 6:
When dividing 1589 by 839, we get 1 with a remainder of 750.
Write down 1 as next digit of the result. 
Result so far: 801.0
Subtracting 839 from 1589 leaves us with 750.
Fetch the next digit (1) from the dividend, attach it to 750 and continue: 7501 / 839

Let's proceed to step 7:
839 goes into 7501 8 times with a remainder of 789.
Record the quotient 8 as the next digit in the result. 
Result so far: 8018.0
Subtracting 6712 from 7501 leaves us with 789.
Include the next digit (1) from the dividend after 789, then repeat: 7891 / 839

On to step 8:
839 goes into 7891 9 times with a remainder of 340.
The number 9 becomes the next digit in our result. 
Result so far: 80189.0
If we take 7551 away from 7891, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 9:
839 can be fit into 3400 4 times, resulting in a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 80189.4
Deduct 3356 from 3400 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
839 can be fit into 440 0 times, resulting in a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 80189.4
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
If we divide 4400 by 839, we get 5 and a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 80189.405
If we take 4195 away from 4400, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 12:
The number 839 fits into 2050 2 times, leaving a remainder of 372.
Put 2 as the next digit of the answer. 
Result so far: 80189.4052
Subtract 1678 from 2050 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 13:
When dividing 3720 by 839, we get 4 with a remainder of 364.
Put 4 as the next digit of the answer. 
Result so far: 80189.40524
Subtracting 3356 from 3720 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 14:
When dividing 3640 by 839, we get 4 with a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 80189.405244
Subtract 3356 from 3640 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The quotient of the division is 80189.405244, and the remainder is 2.84e-05.
