We look at the division of 70306226 by 863 
The aim is to understand the frequency of 863 in 70306226.

Advancing to step 1:
If we divide 7 by 863, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 863

Going ahead to step 2:
If we divide 70 by 863, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 863

Advancing to step 3:
When dividing 703 by 863, we get 0 with a remainder of 703.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 703 to get 703.
Include the next digit (0) from the dividend after 703, then repeat: 7030 / 863

On to step 4:
863 can be fit into 7030 8 times, resulting in a remainder of 126.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 6904 away from 7030, we end up with 126.
Fetch the next digit (6) from the dividend, attach it to 126 and continue: 1266 / 863

Going ahead to step 5:
When dividing 1266 by 863, we get 1 with a remainder of 403.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Deduct 863 from 1266 and we're left with 403.
Take the next digit (2) from the dividend and append it to 403, then repeat: 4032 / 863

Moving on to step 6:
When dividing 4032 by 863, we get 4 with a remainder of 580.
The next digit of our result is 4. 
Result so far: 814.0
Deduct 3452 from 4032 and we're left with 580.
Take the next digit (2) from the dividend and append it to 580, then repeat: 5802 / 863

Let's proceed to step 7:
The number 863 fits into 5802 6 times, leaving a remainder of 624.
Record the quotient 6 as the next digit in the result. 
Result so far: 8146.0
Subtract 5178 from 5802 to get 624.
Append the next digit (6) from the dividend to 624 and continue with: 6246 / 863

Let's proceed to step 8:
The number 863 fits into 6246 7 times, leaving a remainder of 205.
Record the quotient 7 as the next digit in the result. 
Result so far: 81467.0
Subtract 6041 from 6246 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 9:
The number 863 fits into 2050 2 times, leaving a remainder of 324.
The number 2 becomes the next digit in our result. 
Result so far: 81467.2
If we subtract 1726 from 2050, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 10:
863 can be fit into 3240 3 times, resulting in a remainder of 651.
Use 3 as the next digit of our solution. 
Result so far: 81467.23
If we subtract 2589 from 3240, we get 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Step 11:
If we divide 6510 by 863, we get 7 and a remainder of 469.
The number 7 becomes the next digit in our result. 
Result so far: 81467.237
If we take 6041 away from 6510, we end up with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Going ahead to step 12:
863 can be fit into 4690 5 times, resulting in a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 81467.2375
The remainder is 375 after subtracting 4315 from 4690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 13:
If we divide 3750 by 863, we get 4 and a remainder of 298.
Write down 4 as next digit of the result. 
Result so far: 81467.23754
The remainder is 298 after subtracting 3452 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 14:
863 can be fit into 2980 3 times, resulting in a remainder of 391.
Put 3 as the next digit of the answer. 
Result so far: 81467.237543
If we take 2589 away from 2980, we end up with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Moving on to step 15:
863 goes into 3910 4 times with a remainder of 458.
Write down 4 as next digit of the result. 
Result so far: 81467.2375434
The remainder is 458 after subtracting 3452 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 16:
When dividing 4580 by 863, we get 5 with a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 81467.23754345
Subtracting 4315 from 4580 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

The final outcome is 81467.23754345, with a leftover of 2.65e-07.
