We're dividing 56408399 by 366 
The aim is to understand the frequency of 366 in 56408399.

Moving on to step 1:
366 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 366

Let's proceed to step 2:
366 can be fit into 56 0 times, resulting in a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 366

Let's proceed to step 3:
366 can be fit into 564 1 times, resulting in a remainder of 198.
The next digit of our result is 1. 
Result so far: 1.0
If we take 366 away from 564, we end up with 198.
Fetch the next digit (0) from the dividend, attach it to 198 and continue: 1980 / 366

Let's proceed to step 4:
When dividing 1980 by 366, we get 5 with a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 1830 from 1980 leaves us with 150.
Take the next digit (8) from the dividend and append it to 150, then repeat: 1508 / 366

Let's proceed to step 5:
1508 divided by 366 is 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
Subtracting 1464 from 1508 leaves us with 44.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 366

Going ahead to step 6:
If we divide 443 by 366, we get 1 and a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 1541.0
If we take 366 away from 443, we end up with 77.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 366

Step 7:
366 can be fit into 779 2 times, resulting in a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 15412.0
Deduct 732 from 779 and we're left with 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 366

Advancing to step 8:
366 can be fit into 479 1 times, resulting in a remainder of 113.
The number 1 becomes the next digit in our result. 
Result so far: 154121.0
If we subtract 366 from 479, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 9:
1130 divided by 366 is 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 154121.3
Deduct 1098 from 1130 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
366 goes into 320 0 times with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 154121.3
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 11:
The number 366 fits into 3200 8 times, leaving a remainder of 272.
Put 8 as the next digit of the answer. 
Result so far: 154121.308
Subtract 2928 from 3200 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 12:
366 can be fit into 2720 7 times, resulting in a remainder of 158.
Put 7 as the next digit of the answer. 
Result so far: 154121.3087
If we take 2562 away from 2720, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 13:
If we divide 1580 by 366, we get 4 and a remainder of 116.
The next digit of our result is 4. 
Result so far: 154121.30874
If we take 1464 away from 1580, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 14:
366 can be fit into 1160 3 times, resulting in a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 154121.308743
If we take 1098 away from 1160, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 15:
620 divided by 366 is 1 with a remainder of 254.
Record the quotient 1 as the next digit in the result. 
Result so far: 154121.3087431
If we take 366 away from 620, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 16:
366 can be fit into 2540 6 times, resulting in a remainder of 344.
The next digit of our result is 6. 
Result so far: 154121.30874316
Deduct 2196 from 2540 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The quotient of the division is 154121.30874316, and the remainder is 3.44e-07.
