We look at the division of 36718920 by 408 
The aim is to understand the frequency of 408 in 36718920.

Moving on to step 1:
When dividing 3 by 408, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 408

On to step 2:
36 divided by 408 is 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Grab the next digit (7) from the dividend, add it to 36, then carry on: 367 / 408

Moving on to step 3:
408 can be fit into 367 0 times, resulting in a remainder of 367.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 367 leaves us with 367.
Append the next digit (1) from the dividend to 367 and continue with: 3671 / 408

On to step 4:
3671 divided by 408 is 8 with a remainder of 407.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 3264 away from 3671, we end up with 407.
Take the next digit (8) from the dividend and append it to 407, then repeat: 4078 / 408

Step 5:
4078 divided by 408 is 9 with a remainder of 406.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Deduct 3672 from 4078 and we're left with 406.
Grab the next digit (9) from the dividend, add it to 406, then carry on: 4069 / 408

Moving on to step 6:
If we divide 4069 by 408, we get 9 and a remainder of 397.
The number 9 becomes the next digit in our result. 
Result so far: 899.0
If we subtract 3672 from 4069, we get 397.
Grab the next digit (2) from the dividend, add it to 397, then carry on: 3972 / 408

Step 7:
When dividing 3972 by 408, we get 9 with a remainder of 300.
Put 9 as the next digit of the answer. 
Result so far: 8999.0
If we take 3672 away from 3972, we end up with 300.
Fetch the next digit (0) from the dividend, attach it to 300 and continue: 3000 / 408

Let's proceed to step 8:
408 can be fit into 3000 7 times, resulting in a remainder of 144.
Record the quotient 7 as the next digit in the result. 
Result so far: 89997.0
Subtracting 2856 from 3000 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.

Going ahead to step 9:
1440 divided by 408 is 3 with a remainder of 216.
Write down 3 as next digit of the result. 
Result so far: 89997.3
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 10:
408 goes into 2160 5 times with a remainder of 120.
The next digit of our result is 5. 
Result so far: 89997.35
Deduct 2040 from 2160 and we're left 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.

Let's proceed to step 11:
If we divide 1200 by 408, we get 2 and a remainder of 384.
Write down 2 as next digit of the result. 
Result so far: 89997.352
If we subtract 816 from 1200, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 12:
When dividing 3840 by 408, we get 9 with a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 89997.3529
Subtracting 3672 from 3840 leaves us with 168.
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 13:
1680 divided by 408 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 89997.35294
If we subtract 1632 from 1680, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 14:
480 divided by 408 is 1 with a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 89997.352941
The remainder is 72 after subtracting 408 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 15:
The number 408 fits into 720 1 times, leaving a remainder of 312.
Write down 1 as next digit of the result. 
Result so far: 89997.3529411
If we take 408 away from 720, we end up with 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 89997.3529411, with a leftover of 3.12e-06.
