We divide 15618482 by 408
The aim is to understand the frequency of 408 in 15618482.

Let's proceed to step 1:
The number 408 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 408

Moving on to step 2:
15 divided by 408 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 408

Going ahead to step 3:
408 goes into 156 0 times with a remainder of 156.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 156 leaves us with 156.
Grab the next digit (1) from the dividend, add it to 156, then carry on: 1561 / 408

Advancing to step 4:
When dividing 1561 by 408, we get 3 with a remainder of 337.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 1224 from 1561 to get 337.
Take the next digit (8) from the dividend and append it to 337, then repeat: 3378 / 408

Advancing to step 5:
When dividing 3378 by 408, we get 8 with a remainder of 114.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we subtract 3264 from 3378, we get 114.
Append the next digit (4) from the dividend to 114 and continue with: 1144 / 408

Going ahead to step 6:
The number 408 fits into 1144 2 times, leaving a remainder of 328.
Use 2 as the next digit of our solution. 
Result so far: 382.0
If we take 816 away from 1144, we end up with 328.
Take the next digit (8) from the dividend and append it to 328, then repeat: 3288 / 408

On to step 7:
408 can be fit into 3288 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 3828.0
Subtracting 3264 from 3288 leaves us with 24.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 408

Step 8:
If we divide 242 by 408, we get 0 and a remainder of 242.
Put 0 as the next digit of the answer. 
Result so far: 38280.0
If we take 0 away from 242, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 9:
408 goes into 2420 5 times with a remainder of 380.
The next digit of our result is 5. 
Result so far: 38280.5
If we take 2040 away from 2420, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 10:
If we divide 3800 by 408, we get 9 and a remainder of 128.
Write down 9 as next digit of the result. 
Result so far: 38280.59
If we subtract 3672 from 3800, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 11:
1280 divided by 408 is 3 with a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 38280.593
If we subtract 1224 from 1280, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
408 goes into 560 1 times with a remainder of 152.
Put 1 as the next digit of the answer. 
Result so far: 38280.5931
The remainder is 152 after subtracting 408 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 13:
408 goes into 1520 3 times with a remainder of 296.
The number 3 becomes the next digit in our result. 
Result so far: 38280.59313
If we subtract 1224 from 1520, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 14:
If we divide 2960 by 408, we get 7 and a remainder of 104.
Record the quotient 7 as the next digit in the result. 
Result so far: 38280.593137
Subtract 2856 from 2960 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.

Advancing to step 15:
408 can be fit into 1040 2 times, resulting in a remainder of 224.
The next digit of our result is 2. 
Result so far: 38280.5931372
The remainder is 224 after subtracting 816 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 16:
2240 divided by 408 is 5 with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 38280.59313725
Deduct 2040 from 2240 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 38280.59313725 with a remainder of 2e-07.
