7277370 ÷ 402 
The aim is to understand the frequency of 402 in 7277370.

Let's proceed to step 1:
When dividing 7 by 402, we get 0 with 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.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 402

Let's proceed to step 2:
402 can be fit into 72 0 times, resulting in a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Include the next digit (7) from the dividend after 72, then repeat: 727 / 402

Moving on to step 3:
If we divide 727 by 402, we get 1 and a remainder of 325.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 402 from 727, we get 325.
Bring next digit (7) of the dividend behind the 325 and repeat the process: 3257 / 402

Let's proceed to step 4:
If we divide 3257 by 402, we get 8 and a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 3216 from 3257 to get 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 402

Going ahead to step 5:
If we divide 413 by 402, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
Deduct 402 from 413 and we're left with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 402

Step 6:
402 can be fit into 117 0 times, resulting in a remainder of 117.
The next digit of our result is 0. 
Result so far: 1810.0
Subtracting 0 from 117 leaves us with 117.
Fetch the next digit (0) from the dividend, attach it to 117 and continue: 1170 / 402

Let's proceed to step 7:
402 can be fit into 1170 2 times, resulting in a remainder of 366.
The number 2 becomes the next digit in our result. 
Result so far: 18102.0
Subtract 804 from 1170 to get 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 8:
402 can be fit into 3660 9 times, resulting in a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 18102.9
If we take 3618 away from 3660, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
If we divide 420 by 402, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 18102.91
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.

Advancing to step 10:
402 can be fit into 180 0 times, resulting in a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 18102.91
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 11:
When dividing 1800 by 402, we get 4 with a remainder of 192.
The number 4 becomes the next digit in our result. 
Result so far: 18102.9104
The remainder is 192 after subtracting 1608 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 12:
402 goes into 1920 4 times with a remainder of 312.
Use 4 as the next digit of our solution. 
Result so far: 18102.91044
Subtracting 1608 from 1920 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

In conclusion, the division gives 18102.91044 with a balance of 0.000312.
