We look at the division of 73334937 by 402 
The aim is to understand the frequency of 402 in 73334937.

On to step 1:
The number 402 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 402

Let's proceed to step 2:
402 goes into 73 0 times with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Bring next digit (3) of the dividend behind the 73 and repeat the process: 733 / 402

Going ahead to step 3:
733 divided by 402 is 1 with a remainder of 331.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 402 from 733 and we're left with 331.
Include the next digit (3) from the dividend after 331, then repeat: 3313 / 402

On to step 4:
The number 402 fits into 3313 8 times, leaving a remainder of 97.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 97 after subtracting 3216 from 3313.
Fetch the next digit (4) from the dividend, attach it to 97 and continue: 974 / 402

Going ahead to step 5:
974 divided by 402 is 2 with a remainder of 170.
Write down 2 as next digit of the result. 
Result so far: 182.0
Subtract 804 from 974 to get 170.
Fetch the next digit (9) from the dividend, attach it to 170 and continue: 1709 / 402

Moving on to step 6:
If we divide 1709 by 402, we get 4 and a remainder of 101.
The next digit of our result is 4. 
Result so far: 1824.0
The remainder is 101 after subtracting 1608 from 1709.
Append the next digit (3) from the dividend to 101 and continue with: 1013 / 402

On to step 7:
If we divide 1013 by 402, we get 2 and a remainder of 209.
Record the quotient 2 as the next digit in the result. 
Result so far: 18242.0
Subtracting 804 from 1013 leaves us with 209.
Include the next digit (7) from the dividend after 209, then repeat: 2097 / 402

Going ahead to step 8:
When dividing 2097 by 402, we get 5 with a remainder of 87.
Record the quotient 5 as the next digit in the result. 
Result so far: 182425.0
Deduct 2010 from 2097 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 9:
If we divide 870 by 402, we get 2 and a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 182425.2
Subtract 804 from 870 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
402 can be fit into 660 1 times, resulting in a remainder of 258.
The number 1 becomes the next digit in our result. 
Result so far: 182425.21
The remainder is 258 after subtracting 402 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 11:
The number 402 fits into 2580 6 times, leaving a remainder of 168.
Record the quotient 6 as the next digit in the result. 
Result so far: 182425.216
If we take 2412 away from 2580, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 12:
If we divide 1680 by 402, we get 4 and a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 182425.2164
Subtracting 1608 from 1680 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
402 can be fit into 720 1 times, resulting in a remainder of 318.
The next digit of our result is 1. 
Result so far: 182425.21641
Subtract 402 from 720 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 14:
When dividing 3180 by 402, we get 7 with a remainder of 366.
Put 7 as the next digit of the answer. 
Result so far: 182425.216417
Deduct 2814 from 3180 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 15:
The number 402 fits into 3660 9 times, leaving a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 182425.2164179
If we subtract 3618 from 3660, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 16:
The number 402 fits into 420 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 182425.21641791
Deduct 402 from 420 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 182425.21641791, with a leftover of 1.8e-08.
