We divide 78623716 by 839
The aim is to understand the frequency of 839 in 78623716.

Advancing to step 1:
If we divide 7 by 839, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 839

Step 2:
When dividing 78 by 839, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 839

Step 3:
839 can be fit into 786 0 times, resulting in a remainder of 786.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 786 after subtracting 0 from 786.
Bring next digit (2) of the dividend behind the 786 and repeat the process: 7862 / 839

Going ahead to step 4:
If we divide 7862 by 839, we get 9 and a remainder of 311.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 7551 from 7862 and we're left with 311.
Include the next digit (3) from the dividend after 311, then repeat: 3113 / 839

Step 5:
3113 divided by 839 is 3 with a remainder of 596.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
The remainder is 596 after subtracting 2517 from 3113.
Include the next digit (7) from the dividend after 596, then repeat: 5967 / 839

On to step 6:
When dividing 5967 by 839, we get 7 with a remainder of 94.
Use 7 as the next digit of our solution. 
Result so far: 937.0
If we take 5873 away from 5967, we end up with 94.
Grab the next digit (1) from the dividend, add it to 94, then carry on: 941 / 839

Advancing to step 7:
839 can be fit into 941 1 times, resulting in a remainder of 102.
Write down 1 as next digit of the result. 
Result so far: 9371.0
If we subtract 839 from 941, we get 102.
Grab the next digit (6) from the dividend, add it to 102, then carry on: 1026 / 839

On to step 8:
If we divide 1026 by 839, we get 1 and a remainder of 187.
Use 1 as the next digit of our solution. 
Result so far: 93711.0
The remainder is 187 after subtracting 839 from 1026.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 9:
If we divide 1870 by 839, we get 2 and a remainder of 192.
Put 2 as the next digit of the answer. 
Result so far: 93711.2
If we subtract 1678 from 1870, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 10:
839 can be fit into 1920 2 times, resulting in a remainder of 242.
The next digit of our result is 2. 
Result so far: 93711.22
If we take 1678 away from 1920, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

In conclusion, the division gives 93711.22 with a balance of 0.242.
