We divide 31645776 by 839
The aim is to understand the frequency of 839 in 31645776.

Going ahead to step 1:
839 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 839

Let's proceed to step 2:
If we divide 31 by 839, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 839

Moving on to step 3:
If we divide 316 by 839, we get 0 and a remainder of 316.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 316 after subtracting 0 from 316.
Fetch the next digit (4) from the dividend, attach it to 316 and continue: 3164 / 839

Advancing to step 4:
839 goes into 3164 3 times with a remainder of 647.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2517 from 3164, we get 647.
Fetch the next digit (5) from the dividend, attach it to 647 and continue: 6475 / 839

Going ahead to step 5:
839 can be fit into 6475 7 times, resulting in a remainder of 602.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 5873 from 6475 to get 602.
Include the next digit (7) from the dividend after 602, then repeat: 6027 / 839

Step 6:
The number 839 fits into 6027 7 times, leaving a remainder of 154.
Record the quotient 7 as the next digit in the result. 
Result so far: 377.0
If we subtract 5873 from 6027, we get 154.
Include the next digit (7) from the dividend after 154, then repeat: 1547 / 839

On to step 7:
839 can be fit into 1547 1 times, resulting in a remainder of 708.
Record the quotient 1 as the next digit in the result. 
Result so far: 3771.0
Subtract 839 from 1547 to get 708.
Append the next digit (6) from the dividend to 708 and continue with: 7086 / 839

On to step 8:
When dividing 7086 by 839, we get 8 with a remainder of 374.
Record the quotient 8 as the next digit in the result. 
Result so far: 37718.0
Subtract 6712 from 7086 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 9:
839 goes into 3740 4 times with a remainder of 384.
Write down 4 as next digit of the result. 
Result so far: 37718.4
Subtract 3356 from 3740 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 10:
If we divide 3840 by 839, we get 4 and a remainder of 484.
The next digit of our result is 4. 
Result so far: 37718.44
If we subtract 3356 from 3840, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

After the division, we end up with 37718.44 and a remainder of 0.484.
