13392479 divided by 402 
The aim is to understand the frequency of 402 in 13392479.

Advancing to step 1:
If we divide 1 by 402, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 402

On to step 2:
The number 402 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 402

On to step 3:
When dividing 133 by 402, we get 0 with a remainder of 133.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 133, we get 133.
Grab the next digit (9) from the dividend, add it to 133, then carry on: 1339 / 402

Going ahead to step 4:
402 goes into 1339 3 times with a remainder of 133.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 133 after subtracting 1206 from 1339.
Include the next digit (2) from the dividend after 133, then repeat: 1332 / 402

Advancing to step 5:
1332 divided by 402 is 3 with a remainder of 126.
The next digit of our result is 3. 
Result so far: 33.0
Deduct 1206 from 1332 and we're left with 126.
Include the next digit (4) from the dividend after 126, then repeat: 1264 / 402

Going ahead to step 6:
402 goes into 1264 3 times with a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 333.0
If we take 1206 away from 1264, we end up with 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 402

On to step 7:
When dividing 587 by 402, we get 1 with a remainder of 185.
Use 1 as the next digit of our solution. 
Result so far: 3331.0
Subtract 402 from 587 to get 185.
Fetch the next digit (9) from the dividend, attach it to 185 and continue: 1859 / 402

Step 8:
1859 divided by 402 is 4 with a remainder of 251.
Put 4 as the next digit of the answer. 
Result so far: 33314.0
If we take 1608 away from 1859, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 9:
2510 divided by 402 is 6 with a remainder of 98.
Write down 6 as next digit of the result. 
Result so far: 33314.6
If we subtract 2412 from 2510, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 10:
402 can be fit into 980 2 times, resulting in a remainder of 176.
The number 2 becomes the next digit in our result. 
Result so far: 33314.62
Subtracting 804 from 980 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 11:
402 goes into 1760 4 times with a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 33314.624
The remainder is 152 after subtracting 1608 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 12:
If we divide 1520 by 402, we get 3 and a remainder of 314.
Use 3 as the next digit of our solution. 
Result so far: 33314.6243
Subtracting 1206 from 1520 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 13:
If we divide 3140 by 402, we get 7 and a remainder of 326.
The number 7 becomes the next digit in our result. 
Result so far: 33314.62437
The remainder is 326 after subtracting 2814 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 14:
402 can be fit into 3260 8 times, resulting in a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 33314.624378
If we take 3216 away from 3260, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 15:
440 divided by 402 is 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 33314.6243781
If we subtract 402 from 440, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 16:
When dividing 380 by 402, we get 0 with a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 33314.6243781
If we take 0 away from 380, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 33314.6243781 with a remainder of 3.8e-07.
