We look at the division of 76881870 by 364 
The aim is to understand the frequency of 364 in 76881870.

Let's proceed to step 1:
7 divided by 364 is 0 with 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.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 364

On to step 2:
76 divided by 364 is 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Bring next digit (8) of the dividend behind the 76 and repeat the process: 768 / 364

Let's proceed to step 3:
If we divide 768 by 364, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 728 from 768 to get 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 364

On to step 4:
364 can be fit into 408 1 times, resulting in a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 364 from 408 leaves us with 44.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 364

Advancing to step 5:
441 divided by 364 is 1 with a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 211.0
The remainder is 77 after subtracting 364 from 441.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 364

On to step 6:
778 divided by 364 is 2 with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 2112.0
Deduct 728 from 778 and we're left with 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 364

Going ahead to step 7:
The number 364 fits into 507 1 times, leaving a remainder of 143.
Use 1 as the next digit of our solution. 
Result so far: 21121.0
Subtracting 364 from 507 leaves us with 143.
Take the next digit (0) from the dividend and append it to 143, then repeat: 1430 / 364

Advancing to step 8:
If we divide 1430 by 364, we get 3 and a remainder of 338.
The next digit of our result is 3. 
Result so far: 211213.0
If we subtract 1092 from 1430, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 9:
If we divide 3380 by 364, we get 9 and a remainder of 104.
Write down 9 as next digit of the result. 
Result so far: 211213.9
The remainder is 104 after subtracting 3276 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 10:
When dividing 1040 by 364, we get 2 with a remainder of 312.
Write down 2 as next digit of the result. 
Result so far: 211213.92
If we subtract 728 from 1040, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 11:
If we divide 3120 by 364, we get 8 and a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 211213.928
The remainder is 208 after subtracting 2912 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 12:
The number 364 fits into 2080 5 times, leaving a remainder of 260.
The number 5 becomes the next digit in our result. 
Result so far: 211213.9285
If we subtract 1820 from 2080, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 13:
If we divide 2600 by 364, we get 7 and a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 211213.92857
Deduct 2548 from 2600 and we're left 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.

Advancing to step 14:
364 goes into 520 1 times with a remainder of 156.
Put 1 as the next digit of the answer. 
Result so far: 211213.928571
The remainder is 156 after subtracting 364 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 15:
The number 364 fits into 1560 4 times, leaving a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 211213.9285714
Subtract 1456 from 1560 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 16:
If we divide 1040 by 364, we get 2 and a remainder of 312.
Use 2 as the next digit of our solution. 
Result so far: 211213.92857142
If we subtract 728 from 1040, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final outcome is 211213.92857142, with a leftover of 3.12e-07.
