30867717 ÷ 386 
The aim is to understand the frequency of 386 in 30867717.

Advancing to step 1:
If we divide 3 by 386, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 386

Moving on to step 2:
386 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 386

Moving on to step 3:
If we divide 308 by 386, we get 0 and a remainder of 308.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 308 and we're left with 308.
Fetch the next digit (6) from the dividend, attach it to 308 and continue: 3086 / 386

Advancing to step 4:
3086 divided by 386 is 7 with a remainder of 384.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 2702 away from 3086, we end up with 384.
Include the next digit (7) from the dividend after 384, then repeat: 3847 / 386

Moving on to step 5:
If we divide 3847 by 386, we get 9 and a remainder of 373.
Put 9 as the next digit of the answer. 
Result so far: 79.0
The remainder is 373 after subtracting 3474 from 3847.
Take the next digit (7) from the dividend and append it to 373, then repeat: 3737 / 386

Going ahead to step 6:
The number 386 fits into 3737 9 times, leaving a remainder of 263.
Put 9 as the next digit of the answer. 
Result so far: 799.0
Deduct 3474 from 3737 and we're left with 263.
Fetch the next digit (1) from the dividend, attach it to 263 and continue: 2631 / 386

On to step 7:
If we divide 2631 by 386, we get 6 and a remainder of 315.
The next digit of our result is 6. 
Result so far: 7996.0
If we take 2316 away from 2631, we end up with 315.
Bring next digit (7) of the dividend behind the 315 and repeat the process: 3157 / 386

Let's proceed to step 8:
386 can be fit into 3157 8 times, resulting in a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 79968.0
If we subtract 3088 from 3157, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 9:
When dividing 690 by 386, we get 1 with a remainder of 304.
Use 1 as the next digit of our solution. 
Result so far: 79968.1
If we subtract 386 from 690, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 10:
386 goes into 3040 7 times with a remainder of 338.
The number 7 becomes the next digit in our result. 
Result so far: 79968.17
Deduct 2702 from 3040 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 11:
386 can be fit into 3380 8 times, resulting in a remainder of 292.
Put 8 as the next digit of the answer. 
Result so far: 79968.178
If we subtract 3088 from 3380, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 12:
2920 divided by 386 is 7 with a remainder of 218.
Record the quotient 7 as the next digit in the result. 
Result so far: 79968.1787
If we take 2702 away from 2920, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 13:
386 goes into 2180 5 times with a remainder of 250.
The next digit of our result is 5. 
Result so far: 79968.17875
If we take 1930 away from 2180, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 14:
When dividing 2500 by 386, we get 6 with a remainder of 184.
The number 6 becomes the next digit in our result. 
Result so far: 79968.178756
Deduct 2316 from 2500 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 15:
1840 divided by 386 is 4 with a remainder of 296.
Write down 4 as next digit of the result. 
Result so far: 79968.1787564
Deduct 1544 from 1840 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 16:
386 goes into 2960 7 times with a remainder of 258.
Record the quotient 7 as the next digit in the result. 
Result so far: 79968.17875647
Subtracting 2702 from 2960 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

The final outcome is 79968.17875647, with a leftover of 2.58e-07.
