2665883 divided by 839 
The aim is to understand the frequency of 839 in 2665883.

On to step 1:
839 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 839

Let's proceed to step 2:
26 divided by 839 is 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 839

Moving on to step 3:
266 divided by 839 is 0 with a remainder of 266.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 266 and we're left with 266.
Fetch the next digit (5) from the dividend, attach it to 266 and continue: 2665 / 839

Advancing to step 4:
839 can be fit into 2665 3 times, resulting in a remainder of 148.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 148 after subtracting 2517 from 2665.
Include the next digit (8) from the dividend after 148, then repeat: 1488 / 839

Advancing to step 5:
839 can be fit into 1488 1 times, resulting in a remainder of 649.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Deduct 839 from 1488 and we're left with 649.
Bring next digit (8) of the dividend behind the 649 and repeat the process: 6498 / 839

Advancing to step 6:
839 can be fit into 6498 7 times, resulting in a remainder of 625.
The next digit of our result is 7. 
Result so far: 317.0
If we take 5873 away from 6498, we end up with 625.
Include the next digit (3) from the dividend after 625, then repeat: 6253 / 839

Let's proceed to step 7:
839 can be fit into 6253 7 times, resulting in a remainder of 380.
The next digit of our result is 7. 
Result so far: 3177.0
The remainder is 380 after subtracting 5873 from 6253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 8:
839 can be fit into 3800 4 times, resulting in a remainder of 444.
Write down 4 as next digit of the result. 
Result so far: 3177.4
Subtracting 3356 from 3800 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 9:
The number 839 fits into 4440 5 times, leaving a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 3177.45
Deduct 4195 from 4440 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 10:
839 goes into 2450 2 times with a remainder of 772.
The next digit of our result is 2. 
Result so far: 3177.452
If we take 1678 away from 2450, we end up with 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Going ahead to step 11:
The number 839 fits into 7720 9 times, leaving a remainder of 169.
Record the quotient 9 as the next digit in the result. 
Result so far: 3177.4529
If we subtract 7551 from 7720, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 12:
839 goes into 1690 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 3177.45292
If we subtract 1678 from 1690, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
839 goes into 120 0 times with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 3177.45292
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 14:
If we divide 1200 by 839, we get 1 and a remainder of 361.
Record the quotient 1 as the next digit in the result. 
Result so far: 3177.4529201
Deduct 839 from 1200 and we're left with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Moving on to step 15:
839 goes into 3610 4 times with a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 3177.45292014
The remainder is 254 after subtracting 3356 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The final outcome is 3177.45292014, with a leftover of 2.54e-07.
