We look at the division of 38429911 by 402 
The aim is to understand the frequency of 402 in 38429911.

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
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 402

Going ahead to step 2:
402 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 402

Step 3:
The number 402 fits into 384 0 times, leaving a remainder of 384.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 384 after subtracting 0 from 384.
Fetch the next digit (2) from the dividend, attach it to 384 and continue: 3842 / 402

Advancing to step 4:
The number 402 fits into 3842 9 times, leaving a remainder of 224.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 3618 away from 3842, we end up with 224.
Include the next digit (9) from the dividend after 224, then repeat: 2249 / 402

Going ahead to step 5:
402 goes into 2249 5 times with a remainder of 239.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Deduct 2010 from 2249 and we're left with 239.
Grab the next digit (9) from the dividend, add it to 239, then carry on: 2399 / 402

Going ahead to step 6:
2399 divided by 402 is 5 with a remainder of 389.
Use 5 as the next digit of our solution. 
Result so far: 955.0
Subtract 2010 from 2399 to get 389.
Take the next digit (1) from the dividend and append it to 389, then repeat: 3891 / 402

Step 7:
402 goes into 3891 9 times with a remainder of 273.
Write down 9 as next digit of the result. 
Result so far: 9559.0
Subtract 3618 from 3891 to get 273.
Take the next digit (1) from the dividend and append it to 273, then repeat: 2731 / 402

Advancing to step 8:
2731 divided by 402 is 6 with a remainder of 319.
Record the quotient 6 as the next digit in the result. 
Result so far: 95596.0
If we take 2412 away from 2731, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Moving on to step 9:
402 goes into 3190 7 times with a remainder of 376.
Use 7 as the next digit of our solution. 
Result so far: 95596.7
Subtracting 2814 from 3190 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 10:
When dividing 3760 by 402, we get 9 with a remainder of 142.
Record the quotient 9 as the next digit in the result. 
Result so far: 95596.79
If we subtract 3618 from 3760, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 11:
402 goes into 1420 3 times with a remainder of 214.
The number 3 becomes the next digit in our result. 
Result so far: 95596.793
Deduct 1206 from 1420 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 12:
The number 402 fits into 2140 5 times, leaving a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 95596.7935
If we subtract 2010 from 2140, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 13:
402 can be fit into 1300 3 times, resulting in a remainder of 94.
Record the quotient 3 as the next digit in the result. 
Result so far: 95596.79353
The remainder is 94 after subtracting 1206 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 14:
The number 402 fits into 940 2 times, leaving a remainder of 136.
Write down 2 as next digit of the result. 
Result so far: 95596.793532
Deduct 804 from 940 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 15:
1360 divided by 402 is 3 with a remainder of 154.
Use 3 as the next digit of our solution. 
Result so far: 95596.7935323
The remainder is 154 after subtracting 1206 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 16:
If we divide 1540 by 402, we get 3 and a remainder of 334.
Write down 3 as next digit of the result. 
Result so far: 95596.79353233
Subtracting 1206 from 1540 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

After the division, we end up with 95596.79353233 and a remainder of 3.34e-07.
