We look at the division of 3932960 by 838 
The aim is to understand the frequency of 838 in 3932960.

On to step 1:
When dividing 3 by 838, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 838

Step 2:
If we divide 39 by 838, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 838

On to step 3:
When dividing 393 by 838, we get 0 with a remainder of 393.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 393 to get 393.
Append the next digit (2) from the dividend to 393 and continue with: 3932 / 838

Moving on to step 4:
When dividing 3932 by 838, we get 4 with a remainder of 580.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 3352 from 3932, we get 580.
Append the next digit (9) from the dividend to 580 and continue with: 5809 / 838

Advancing to step 5:
838 goes into 5809 6 times with a remainder of 781.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we take 5028 away from 5809, we end up with 781.
Bring next digit (6) of the dividend behind the 781 and repeat the process: 7816 / 838

On to step 6:
If we divide 7816 by 838, we get 9 and a remainder of 274.
Use 9 as the next digit of our solution. 
Result so far: 469.0
Subtract 7542 from 7816 to get 274.
Fetch the next digit (0) from the dividend, attach it to 274 and continue: 2740 / 838

Advancing to step 7:
838 can be fit into 2740 3 times, resulting in a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 4693.0
Subtracting 2514 from 2740 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 8:
838 can be fit into 2260 2 times, resulting in a remainder of 584.
Record the quotient 2 as the next digit in the result. 
Result so far: 4693.2
Deduct 1676 from 2260 and we're left with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Advancing to step 9:
838 can be fit into 5840 6 times, resulting in a remainder of 812.
Write down 6 as next digit of the result. 
Result so far: 4693.26
Subtract 5028 from 5840 to get 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Step 10:
The number 838 fits into 8120 9 times, leaving a remainder of 578.
The next digit of our result is 9. 
Result so far: 4693.269
If we take 7542 away from 8120, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

On to step 11:
When dividing 5780 by 838, we get 6 with a remainder of 752.
Put 6 as the next digit of the answer. 
Result so far: 4693.2696
Subtract 5028 from 5780 to get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Going ahead to step 12:
When dividing 7520 by 838, we get 8 with a remainder of 816.
Use 8 as the next digit of our solution. 
Result so far: 4693.26968
The remainder is 816 after subtracting 6704 from 7520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Advancing to step 13:
The number 838 fits into 8160 9 times, leaving a remainder of 618.
Use 9 as the next digit of our solution. 
Result so far: 4693.269689
If we subtract 7542 from 8160, we get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

On to step 14:
838 goes into 6180 7 times with a remainder of 314.
Record the quotient 7 as the next digit in the result. 
Result so far: 4693.2696897
Subtracting 5866 from 6180 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 15:
838 goes into 3140 3 times with a remainder of 626.
The next digit of our result is 3. 
Result so far: 4693.26968973
Deduct 2514 from 3140 and we're left with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

The final outcome is 4693.26968973, with a leftover of 6.26e-07.
