78004901 divided by 366 
The aim is to understand the frequency of 366 in 78004901.

Step 1:
7 divided by 366 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 366

Going ahead to step 2:
If we divide 78 by 366, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 366

Advancing to step 3:
The number 366 fits into 780 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 732 from 780 and we're left with 48.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 366

Moving on to step 4:
When dividing 480 by 366, we get 1 with a remainder of 114.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 114 after subtracting 366 from 480.
Fetch the next digit (4) from the dividend, attach it to 114 and continue: 1144 / 366

Moving on to step 5:
The number 366 fits into 1144 3 times, leaving a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
Subtract 1098 from 1144 to get 46.
Append the next digit (9) from the dividend to 46 and continue with: 469 / 366

On to step 6:
The number 366 fits into 469 1 times, leaving a remainder of 103.
The next digit of our result is 1. 
Result so far: 2131.0
Subtract 366 from 469 to get 103.
Fetch the next digit (0) from the dividend, attach it to 103 and continue: 1030 / 366

Let's proceed to step 7:
When dividing 1030 by 366, we get 2 with a remainder of 298.
The next digit of our result is 2. 
Result so far: 21312.0
If we subtract 732 from 1030, we get 298.
Append the next digit (1) from the dividend to 298 and continue with: 2981 / 366

Going ahead to step 8:
2981 divided by 366 is 8 with a remainder of 53.
Put 8 as the next digit of the answer. 
Result so far: 213128.0
Deduct 2928 from 2981 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
530 divided by 366 is 1 with a remainder of 164.
The next digit of our result is 1. 
Result so far: 213128.1
If we subtract 366 from 530, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 10:
If we divide 1640 by 366, we get 4 and a remainder of 176.
Use 4 as the next digit of our solution. 
Result so far: 213128.14
The remainder is 176 after subtracting 1464 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 11:
366 goes into 1760 4 times with a remainder of 296.
The next digit of our result is 4. 
Result so far: 213128.144
The remainder is 296 after subtracting 1464 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

After the division, we end up with 213128.144 and a remainder of 0.0296.
