82388978 divided by 428 
The aim is to understand the frequency of 428 in 82388978.

Step 1:
When dividing 8 by 428, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 428

Advancing to step 2:
82 divided by 428 is 0 with a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Include the next digit (3) from the dividend after 82, then repeat: 823 / 428

Moving on to step 3:
If we divide 823 by 428, we get 1 and a remainder of 395.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 428 from 823 and we're left with 395.
Bring next digit (8) of the dividend behind the 395 and repeat the process: 3958 / 428

Let's proceed to step 4:
428 can be fit into 3958 9 times, resulting in a remainder of 106.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 3852 from 3958 leaves us with 106.
Grab the next digit (8) from the dividend, add it to 106, then carry on: 1068 / 428

Going ahead to step 5:
If we divide 1068 by 428, we get 2 and a remainder of 212.
The next digit of our result is 2. 
Result so far: 192.0
Subtract 856 from 1068 to get 212.
Append the next digit (9) from the dividend to 212 and continue with: 2129 / 428

On to step 6:
2129 divided by 428 is 4 with a remainder of 417.
The number 4 becomes the next digit in our result. 
Result so far: 1924.0
The remainder is 417 after subtracting 1712 from 2129.
Take the next digit (7) from the dividend and append it to 417, then repeat: 4177 / 428

Going ahead to step 7:
4177 divided by 428 is 9 with a remainder of 325.
The next digit of our result is 9. 
Result so far: 19249.0
If we take 3852 away from 4177, we end up with 325.
Grab the next digit (8) from the dividend, add it to 325, then carry on: 3258 / 428

Let's proceed to step 8:
428 goes into 3258 7 times with a remainder of 262.
Use 7 as the next digit of our solution. 
Result so far: 192497.0
Deduct 2996 from 3258 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 9:
When dividing 2620 by 428, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 192497.6
If we take 2568 away from 2620, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
520 divided by 428 is 1 with a remainder of 92.
Use 1 as the next digit of our solution. 
Result so far: 192497.61
If we subtract 428 from 520, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 11:
428 can be fit into 920 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 192497.612
Deduct 856 from 920 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
640 divided by 428 is 1 with a remainder of 212.
Use 1 as the next digit of our solution. 
Result so far: 192497.6121
If we take 428 away from 640, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 13:
2120 divided by 428 is 4 with a remainder of 408.
Write down 4 as next digit of the result. 
Result so far: 192497.61214
If we subtract 1712 from 2120, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 14:
428 goes into 4080 9 times with a remainder of 228.
Use 9 as the next digit of our solution. 
Result so far: 192497.612149
If we take 3852 away from 4080, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 15:
When dividing 2280 by 428, we get 5 with a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 192497.6121495
The remainder is 140 after subtracting 2140 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 16:
When dividing 1400 by 428, we get 3 with a remainder of 116.
Record the quotient 3 as the next digit in the result. 
Result so far: 192497.61214953
Subtract 1284 from 1400 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final outcome is 192497.61214953, with a leftover of 1.16e-07.
