64224631 ÷ 838 
The aim is to understand the frequency of 838 in 64224631.

Advancing to step 1:
When dividing 6 by 838, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 838

Let's proceed to step 2:
When dividing 64 by 838, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 838

Moving on to step 3:
When dividing 642 by 838, we get 0 with a remainder of 642.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 642, we end up with 642.
Take the next digit (2) from the dividend and append it to 642, then repeat: 6422 / 838

Moving on to step 4:
The number 838 fits into 6422 7 times, leaving a remainder of 556.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 5866 from 6422 to get 556.
Grab the next digit (4) from the dividend, add it to 556, then carry on: 5564 / 838

On to step 5:
When dividing 5564 by 838, we get 6 with a remainder of 536.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Deduct 5028 from 5564 and we're left with 536.
Take the next digit (6) from the dividend and append it to 536, then repeat: 5366 / 838

Let's proceed to step 6:
838 goes into 5366 6 times with a remainder of 338.
Record the quotient 6 as the next digit in the result. 
Result so far: 766.0
The remainder is 338 after subtracting 5028 from 5366.
Include the next digit (3) from the dividend after 338, then repeat: 3383 / 838

Moving on to step 7:
3383 divided by 838 is 4 with a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 7664.0
If we subtract 3352 from 3383, we get 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 838

Moving on to step 8:
838 goes into 311 0 times with a remainder of 311.
Write down 0 as next digit of the result. 
Result so far: 76640.0
The remainder is 311 after subtracting 0 from 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 9:
838 can be fit into 3110 3 times, resulting in a remainder of 596.
The next digit of our result is 3. 
Result so far: 76640.3
The remainder is 596 after subtracting 2514 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 10:
5960 divided by 838 is 7 with a remainder of 94.
The next digit of our result is 7. 
Result so far: 76640.37
Deduct 5866 from 5960 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 11:
When dividing 940 by 838, we get 1 with a remainder of 102.
Write down 1 as next digit of the result. 
Result so far: 76640.371
Deduct 838 from 940 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 12:
The number 838 fits into 1020 1 times, leaving a remainder of 182.
Write down 1 as next digit of the result. 
Result so far: 76640.3711
Subtracting 838 from 1020 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The final outcome is 76640.3711, with a leftover of 0.00182.
