77312892 divided by 408 
The aim is to understand the frequency of 408 in 77312892.

Advancing to step 1:
408 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 408

Moving on to step 2:
The number 408 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 408

Going ahead to step 3:
773 divided by 408 is 1 with a remainder of 365.
The next digit of our result is 1. 
Result so far: 1.0
If we take 408 away from 773, we end up with 365.
Fetch the next digit (1) from the dividend, attach it to 365 and continue: 3651 / 408

On to step 4:
3651 divided by 408 is 8 with a remainder of 387.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 3264 from 3651 leaves us with 387.
Include the next digit (2) from the dividend after 387, then repeat: 3872 / 408

Step 5:
408 goes into 3872 9 times with a remainder of 200.
Use 9 as the next digit of our solution. 
Result so far: 189.0
If we subtract 3672 from 3872, we get 200.
Include the next digit (8) from the dividend after 200, then repeat: 2008 / 408

Let's proceed to step 6:
2008 divided by 408 is 4 with a remainder of 376.
The next digit of our result is 4. 
Result so far: 1894.0
The remainder is 376 after subtracting 1632 from 2008.
Grab the next digit (9) from the dividend, add it to 376, then carry on: 3769 / 408

On to step 7:
When dividing 3769 by 408, we get 9 with a remainder of 97.
Write down 9 as next digit of the result. 
Result so far: 18949.0
If we take 3672 away from 3769, we end up with 97.
Take the next digit (2) from the dividend and append it to 97, then repeat: 972 / 408

Let's proceed to step 8:
If we divide 972 by 408, we get 2 and a remainder of 156.
The number 2 becomes the next digit in our result. 
Result so far: 189492.0
The remainder is 156 after subtracting 816 from 972.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 9:
1560 divided by 408 is 3 with a remainder of 336.
The next digit of our result is 3. 
Result so far: 189492.3
Subtract 1224 from 1560 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 10:
If we divide 3360 by 408, we get 8 and a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 189492.38
If we take 3264 away from 3360, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 11:
408 goes into 960 2 times with a remainder of 144.
Use 2 as the next digit of our solution. 
Result so far: 189492.382
Subtracting 816 from 960 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 12:
408 can be fit into 1440 3 times, resulting in a remainder of 216.
Record the quotient 3 as the next digit in the result. 
Result so far: 189492.3823
Deduct 1224 from 1440 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 13:
2160 divided by 408 is 5 with a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 189492.38235
If we take 2040 away from 2160, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 14:
408 goes into 1200 2 times with a remainder of 384.
The next digit of our result is 2. 
Result so far: 189492.382352
If we take 816 away from 1200, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 15:
408 goes into 3840 9 times with a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 189492.3823529
The remainder is 168 after subtracting 3672 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 16:
408 goes into 1680 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 189492.38235294
The remainder is 48 after subtracting 1632 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 189492.38235294 with a remaining 4.8e-08.
