We divide 30969628 by 402
The aim is to understand the frequency of 402 in 30969628.

Let's proceed to step 1:
When dividing 3 by 402, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 402

Let's proceed to step 2:
402 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 402

Step 3:
309 divided by 402 is 0 with a remainder of 309.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 309 to get 309.
Append the next digit (6) from the dividend to 309 and continue with: 3096 / 402

Advancing to step 4:
402 goes into 3096 7 times with a remainder of 282.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 2814 from 3096 and we're left with 282.
Fetch the next digit (9) from the dividend, attach it to 282 and continue: 2829 / 402

Step 5:
If we divide 2829 by 402, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 77.0
If we subtract 2814 from 2829, we get 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 402

Moving on to step 6:
402 goes into 156 0 times with a remainder of 156.
The next digit of our result is 0. 
Result so far: 770.0
If we subtract 0 from 156, we get 156.
Include the next digit (2) from the dividend after 156, then repeat: 1562 / 402

Advancing to step 7:
1562 divided by 402 is 3 with a remainder of 356.
Record the quotient 3 as the next digit in the result. 
Result so far: 7703.0
The remainder is 356 after subtracting 1206 from 1562.
Bring next digit (8) of the dividend behind the 356 and repeat the process: 3568 / 402

Step 8:
When dividing 3568 by 402, we get 8 with a remainder of 352.
Use 8 as the next digit of our solution. 
Result so far: 77038.0
The remainder is 352 after subtracting 3216 from 3568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 9:
The number 402 fits into 3520 8 times, leaving a remainder of 304.
Use 8 as the next digit of our solution. 
Result so far: 77038.8
If we subtract 3216 from 3520, we 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.

On to step 10:
402 goes into 3040 7 times with a remainder of 226.
Put 7 as the next digit of the answer. 
Result so far: 77038.87
Subtract 2814 from 3040 to get 226.
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 11:
402 can be fit into 2260 5 times, resulting in a remainder of 250.
The next digit of our result is 5. 
Result so far: 77038.875
Subtract 2010 from 2260 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
When dividing 2500 by 402, we get 6 with a remainder of 88.
Use 6 as the next digit of our solution. 
Result so far: 77038.8756
The remainder is 88 after subtracting 2412 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 13:
880 divided by 402 is 2 with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 77038.87562
Subtract 804 from 880 to get 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 14:
760 divided by 402 is 1 with a remainder of 358.
The number 1 becomes the next digit in our result. 
Result so far: 77038.875621
If we subtract 402 from 760, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 15:
402 can be fit into 3580 8 times, resulting in a remainder of 364.
The next digit of our result is 8. 
Result so far: 77038.8756218
Subtract 3216 from 3580 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 16:
If we divide 3640 by 402, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 77038.87562189
If we take 3618 away from 3640, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 77038.87562189, with a leftover of 2.2e-08.
