Let's divide 78281838 by 839
The aim is to understand the frequency of 839 in 78281838.

On to step 1:
839 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 839

Step 2:
The number 839 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 839

Step 3:
839 can be fit into 782 0 times, resulting in a remainder of 782.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 782 to get 782.
Append the next digit (8) from the dividend to 782 and continue with: 7828 / 839

Moving on to step 4:
839 can be fit into 7828 9 times, resulting in a remainder of 277.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 7551 from 7828 to get 277.
Append the next digit (1) from the dividend to 277 and continue with: 2771 / 839

Going ahead to step 5:
839 goes into 2771 3 times with a remainder of 254.
Write down 3 as next digit of the result. 
Result so far: 93.0
Deduct 2517 from 2771 and we're left with 254.
Include the next digit (8) from the dividend after 254, then repeat: 2548 / 839

Going ahead to step 6:
839 goes into 2548 3 times with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 933.0
If we take 2517 away from 2548, we end up with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 839

Moving on to step 7:
839 goes into 313 0 times with a remainder of 313.
Use 0 as the next digit of our solution. 
Result so far: 9330.0
If we subtract 0 from 313, we get 313.
Include the next digit (8) from the dividend after 313, then repeat: 3138 / 839

Advancing to step 8:
When dividing 3138 by 839, we get 3 with a remainder of 621.
The number 3 becomes the next digit in our result. 
Result so far: 93303.0
Subtract 2517 from 3138 to get 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Moving on to step 9:
The number 839 fits into 6210 7 times, leaving a remainder of 337.
Record the quotient 7 as the next digit in the result. 
Result so far: 93303.7
Deduct 5873 from 6210 and we're left with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 10:
839 goes into 3370 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 93303.74
Deduct 3356 from 3370 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
If we divide 140 by 839, we get 0 and a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 93303.74
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
When dividing 1400 by 839, we get 1 with a remainder of 561.
Put 1 as the next digit of the answer. 
Result so far: 93303.7401
If we take 839 away from 1400, we end up with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Let's proceed to step 13:
5610 divided by 839 is 6 with a remainder of 576.
Put 6 as the next digit of the answer. 
Result so far: 93303.74016
Subtracting 5034 from 5610 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 14:
When dividing 5760 by 839, we get 6 with a remainder of 726.
Write down 6 as next digit of the result. 
Result so far: 93303.740166
Subtracting 5034 from 5760 leaves us with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Our division results in 93303.740166 with a remaining 7.26e-05.
