We're dividing 81020463 by 392 
The aim is to understand the frequency of 392 in 81020463.

On to step 1:
When dividing 8 by 392, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 392

Advancing to step 2:
392 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 392

Moving on to step 3:
When dividing 810 by 392, we get 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 784 away from 810, we end up with 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 392

On to step 4:
392 goes into 262 0 times with a remainder of 262.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 262 after subtracting 0 from 262.
Append the next digit (0) from the dividend to 262 and continue with: 2620 / 392

Advancing to step 5:
392 goes into 2620 6 times with a remainder of 268.
Put 6 as the next digit of the answer. 
Result so far: 206.0
If we take 2352 away from 2620, we end up with 268.
Include the next digit (4) from the dividend after 268, then repeat: 2684 / 392

On to step 6:
2684 divided by 392 is 6 with a remainder of 332.
The next digit of our result is 6. 
Result so far: 2066.0
Subtracting 2352 from 2684 leaves us with 332.
Fetch the next digit (6) from the dividend, attach it to 332 and continue: 3326 / 392

Let's proceed to step 7:
When dividing 3326 by 392, we get 8 with a remainder of 190.
Use 8 as the next digit of our solution. 
Result so far: 20668.0
Subtracting 3136 from 3326 leaves us with 190.
Take the next digit (3) from the dividend and append it to 190, then repeat: 1903 / 392

Moving on to step 8:
392 goes into 1903 4 times with a remainder of 335.
Put 4 as the next digit of the answer. 
Result so far: 206684.0
Subtracting 1568 from 1903 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 9:
The number 392 fits into 3350 8 times, leaving a remainder of 214.
The next digit of our result is 8. 
Result so far: 206684.8
The remainder is 214 after subtracting 3136 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 10:
392 goes into 2140 5 times with a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 206684.85
The remainder is 180 after subtracting 1960 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
392 goes into 1800 4 times with a remainder of 232.
Put 4 as the next digit of the answer. 
Result so far: 206684.854
If we subtract 1568 from 1800, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 12:
392 can be fit into 2320 5 times, resulting in a remainder of 360.
Use 5 as the next digit of our solution. 
Result so far: 206684.8545
The remainder is 360 after subtracting 1960 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 13:
The number 392 fits into 3600 9 times, leaving a remainder of 72.
Use 9 as the next digit of our solution. 
Result so far: 206684.85459
The remainder is 72 after subtracting 3528 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
392 goes into 720 1 times with a remainder of 328.
Put 1 as the next digit of the answer. 
Result so far: 206684.854591
Subtracting 392 from 720 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 15:
392 goes into 3280 8 times with a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 206684.8545918
Deduct 3136 from 3280 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 16:
392 can be fit into 1440 3 times, resulting in a remainder of 264.
Record the quotient 3 as the next digit in the result. 
Result so far: 206684.85459183
Deduct 1176 from 1440 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

After the division, we end up with 206684.85459183 and a remainder of 2.64e-07.
