We look at the division of 64015384 by 402 
The aim is to understand the frequency of 402 in 64015384.

On to step 1:
The number 402 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 402

Moving on to step 2:
64 divided by 402 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 402

Going ahead to step 3:
640 divided by 402 is 1 with a remainder of 238.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 402 from 640 leaves us with 238.
Fetch the next digit (1) from the dividend, attach it to 238 and continue: 2381 / 402

On to step 4:
When dividing 2381 by 402, we get 5 with a remainder of 371.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 2010 from 2381 and we're left with 371.
Take the next digit (5) from the dividend and append it to 371, then repeat: 3715 / 402

Step 5:
When dividing 3715 by 402, we get 9 with a remainder of 97.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtracting 3618 from 3715 leaves us with 97.
Append the next digit (3) from the dividend to 97 and continue with: 973 / 402

Advancing to step 6:
When dividing 973 by 402, we get 2 with a remainder of 169.
The number 2 becomes the next digit in our result. 
Result so far: 1592.0
If we take 804 away from 973, we end up with 169.
Include the next digit (8) from the dividend after 169, then repeat: 1698 / 402

Let's proceed to step 7:
The number 402 fits into 1698 4 times, leaving a remainder of 90.
Write down 4 as next digit of the result. 
Result so far: 15924.0
Subtract 1608 from 1698 to get 90.
Fetch the next digit (4) from the dividend, attach it to 90 and continue: 904 / 402

Going ahead to step 8:
When dividing 904 by 402, we get 2 with a remainder of 100.
Write down 2 as next digit of the result. 
Result so far: 159242.0
If we subtract 804 from 904, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 9:
402 can be fit into 1000 2 times, resulting in a remainder of 196.
Put 2 as the next digit of the answer. 
Result so far: 159242.2
If we subtract 804 from 1000, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 10:
When dividing 1960 by 402, we get 4 with a remainder of 352.
Write down 4 as next digit of the result. 
Result so far: 159242.24
Subtracting 1608 from 1960 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 11:
402 can be fit into 3520 8 times, resulting in a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 159242.248
Subtract 3216 from 3520 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 12:
If we divide 3040 by 402, we get 7 and a remainder of 226.
Record the quotient 7 as the next digit in the result. 
Result so far: 159242.2487
The remainder is 226 after subtracting 2814 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 13:
When dividing 2260 by 402, we get 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 159242.24875
Deduct 2010 from 2260 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 14:
The number 402 fits into 2500 6 times, leaving a remainder of 88.
The number 6 becomes the next digit in our result. 
Result so far: 159242.248756
Deduct 2412 from 2500 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 15:
The number 402 fits into 880 2 times, leaving a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 159242.2487562
Deduct 804 from 880 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 16:
If we divide 760 by 402, we get 1 and a remainder of 358.
Put 1 as the next digit of the answer. 
Result so far: 159242.24875621
Deduct 402 from 760 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Our division results in 159242.24875621 with a remaining 3.58e-07.
