10009764 ÷ 402 
The aim is to understand the frequency of 402 in 10009764.

Advancing to step 1:
1 divided by 402 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 402

Step 2:
10 divided by 402 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 402

Moving on to step 3:
402 can be fit into 100 0 times, resulting in a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 100 and we're left with 100.
Append the next digit (0) from the dividend to 100 and continue with: 1000 / 402

Step 4:
402 can be fit into 1000 2 times, resulting in a remainder of 196.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 804 from 1000 and we're left with 196.
Append the next digit (9) from the dividend to 196 and continue with: 1969 / 402

Let's proceed to step 5:
If we divide 1969 by 402, we get 4 and a remainder of 361.
The next digit of our result is 4. 
Result so far: 24.0
If we take 1608 away from 1969, we end up with 361.
Append the next digit (7) from the dividend to 361 and continue with: 3617 / 402

Let's proceed to step 6:
When dividing 3617 by 402, we get 8 with a remainder of 401.
Record the quotient 8 as the next digit in the result. 
Result so far: 248.0
If we take 3216 away from 3617, we end up with 401.
Fetch the next digit (6) from the dividend, attach it to 401 and continue: 4016 / 402

Moving on to step 7:
402 can be fit into 4016 9 times, resulting in a remainder of 398.
Use 9 as the next digit of our solution. 
Result so far: 2489.0
Deduct 3618 from 4016 and we're left with 398.
Grab the next digit (4) from the dividend, add it to 398, then carry on: 3984 / 402

On to step 8:
If we divide 3984 by 402, we get 9 and a remainder of 366.
The number 9 becomes the next digit in our result. 
Result so far: 24899.0
If we subtract 3618 from 3984, we 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.

Going ahead to step 9:
When dividing 3660 by 402, we get 9 with a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 24899.9
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.

Let's proceed to step 10:
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: 24899.91
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.

On to step 11:
When dividing 180 by 402, we get 0 with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 24899.91
Subtract 0 from 180 to 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.

Going ahead to step 12:
The number 402 fits into 1800 4 times, leaving a remainder of 192.
The number 4 becomes the next digit in our result. 
Result so far: 24899.9104
If we subtract 1608 from 1800, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 13:
The number 402 fits into 1920 4 times, leaving a remainder of 312.
Use 4 as the next digit of our solution. 
Result so far: 24899.91044
Deduct 1608 from 1920 and we're left 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.

After the division, we end up with 24899.91044 and a remainder of 0.000312.
