Let's divide 69473555 by 402
The aim is to understand the frequency of 402 in 69473555.

Going ahead to step 1:
When dividing 6 by 402, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 402

Going ahead to step 2:
402 goes into 69 0 times with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Include the next digit (4) from the dividend after 69, then repeat: 694 / 402

Advancing to step 3:
If we divide 694 by 402, we get 1 and a remainder of 292.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 402 from 694 to get 292.
Fetch the next digit (7) from the dividend, attach it to 292 and continue: 2927 / 402

Let's proceed to step 4:
If we divide 2927 by 402, we get 7 and a remainder of 113.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 2814 from 2927 and we're left with 113.
Take the next digit (3) from the dividend and append it to 113, then repeat: 1133 / 402

Step 5:
402 can be fit into 1133 2 times, resulting in a remainder of 329.
The next digit of our result is 2. 
Result so far: 172.0
If we take 804 away from 1133, we end up with 329.
Append the next digit (5) from the dividend to 329 and continue with: 3295 / 402

Moving on to step 6:
402 can be fit into 3295 8 times, resulting in a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 1728.0
Subtract 3216 from 3295 to get 79.
Bring next digit (5) of the dividend behind the 79 and repeat the process: 795 / 402

Moving on to step 7:
795 divided by 402 is 1 with a remainder of 393.
The next digit of our result is 1. 
Result so far: 17281.0
The remainder is 393 after subtracting 402 from 795.
Include the next digit (5) from the dividend after 393, then repeat: 3935 / 402

Let's proceed to step 8:
402 can be fit into 3935 9 times, resulting in a remainder of 317.
The number 9 becomes the next digit in our result. 
Result so far: 172819.0
If we take 3618 away from 3935, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

On to step 9:
402 can be fit into 3170 7 times, resulting in a remainder of 356.
Put 7 as the next digit of the answer. 
Result so far: 172819.7
Subtracting 2814 from 3170 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 10:
The number 402 fits into 3560 8 times, leaving a remainder of 344.
Record the quotient 8 as the next digit in the result. 
Result so far: 172819.78
Deduct 3216 from 3560 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 11:
The number 402 fits into 3440 8 times, leaving a remainder of 224.
Record the quotient 8 as the next digit in the result. 
Result so far: 172819.788
Subtract 3216 from 3440 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final result is 172819.788 with a remainder of 0.0224.
