We look at the division of 86871106 by 392 
The aim is to understand the frequency of 392 in 86871106.

Moving on to step 1:
When dividing 8 by 392, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 392

Advancing to step 2:
392 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 392

Step 3:
868 divided by 392 is 2 with a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 784 from 868 and we're left with 84.
Fetch the next digit (7) from the dividend, attach it to 84 and continue: 847 / 392

On to step 4:
The number 392 fits into 847 2 times, leaving a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 63 after subtracting 784 from 847.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 392

Let's proceed to step 5:
631 divided by 392 is 1 with a remainder of 239.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
Subtract 392 from 631 to get 239.
Bring next digit (1) of the dividend behind the 239 and repeat the process: 2391 / 392

On to step 6:
When dividing 2391 by 392, we get 6 with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 2216.0
If we take 2352 away from 2391, we end up with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 392

Going ahead to step 7:
392 goes into 390 0 times with a remainder of 390.
Record the quotient 0 as the next digit in the result. 
Result so far: 22160.0
The remainder is 390 after subtracting 0 from 390.
Bring next digit (6) of the dividend behind the 390 and repeat the process: 3906 / 392

Advancing to step 8:
3906 divided by 392 is 9 with a remainder of 378.
Record the quotient 9 as the next digit in the result. 
Result so far: 221609.0
Deduct 3528 from 3906 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 9:
If we divide 3780 by 392, we get 9 and a remainder of 252.
Write down 9 as next digit of the result. 
Result so far: 221609.9
If we take 3528 away from 3780, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 10:
2520 divided by 392 is 6 with a remainder of 168.
Use 6 as the next digit of our solution. 
Result so far: 221609.96
If we take 2352 away from 2520, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 11:
392 can be fit into 1680 4 times, resulting in a remainder of 112.
The next digit of our result is 4. 
Result so far: 221609.964
Subtracting 1568 from 1680 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 12:
392 goes into 1120 2 times with a remainder of 336.
Record the quotient 2 as the next digit in the result. 
Result so far: 221609.9642
Subtracting 784 from 1120 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 13:
When dividing 3360 by 392, we get 8 with a remainder of 224.
Use 8 as the next digit of our solution. 
Result so far: 221609.96428
Deduct 3136 from 3360 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 14:
If we divide 2240 by 392, we get 5 and a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 221609.964285
Deduct 1960 from 2240 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
When dividing 2800 by 392, we get 7 with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 221609.9642857
If we subtract 2744 from 2800, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 16:
When dividing 560 by 392, we get 1 with a remainder of 168.
Put 1 as the next digit of the answer. 
Result so far: 221609.96428571
Deduct 392 from 560 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Our division results in 221609.96428571 with a remaining 1.68e-07.
