We divide 81182748 by 404
The aim is to understand the frequency of 404 in 81182748.

Step 1:
8 divided by 404 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 404

Going ahead to step 2:
If we divide 81 by 404, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Append the next digit (1) from the dividend to 81 and continue with: 811 / 404

On to step 3:
The number 404 fits into 811 2 times, leaving a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
If we take 808 away from 811, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 404

Going ahead to step 4:
When dividing 38 by 404, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 38, we get 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 404

On to step 5:
The number 404 fits into 382 0 times, leaving a remainder of 382.
Put 0 as the next digit of the answer. 
Result so far: 200.0
Subtracting 0 from 382 leaves us with 382.
Fetch the next digit (7) from the dividend, attach it to 382 and continue: 3827 / 404

Let's proceed to step 6:
The number 404 fits into 3827 9 times, leaving a remainder of 191.
Record the quotient 9 as the next digit in the result. 
Result so far: 2009.0
If we take 3636 away from 3827, we end up with 191.
Take the next digit (4) from the dividend and append it to 191, then repeat: 1914 / 404

Going ahead to step 7:
If we divide 1914 by 404, we get 4 and a remainder of 298.
Write down 4 as next digit of the result. 
Result so far: 20094.0
The remainder is 298 after subtracting 1616 from 1914.
Include the next digit (8) from the dividend after 298, then repeat: 2988 / 404

Step 8:
404 can be fit into 2988 7 times, resulting in a remainder of 160.
Record the quotient 7 as the next digit in the result. 
Result so far: 200947.0
The remainder is 160 after subtracting 2828 from 2988.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 9:
404 goes into 1600 3 times with a remainder of 388.
The number 3 becomes the next digit in our result. 
Result so far: 200947.3
If we take 1212 away from 1600, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 10:
404 can be fit into 3880 9 times, resulting in a remainder of 244.
The next digit of our result is 9. 
Result so far: 200947.39
If we take 3636 away from 3880, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 11:
The number 404 fits into 2440 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 200947.396
The remainder is 16 after subtracting 2424 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
If we divide 160 by 404, we get 0 and a remainder of 160.
The next digit of our result is 0. 
Result so far: 200947.396
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 13:
404 can be fit into 1600 3 times, resulting in a remainder of 388.
Record the quotient 3 as the next digit in the result. 
Result so far: 200947.39603
Subtracting 1212 from 1600 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 14:
When dividing 3880 by 404, we get 9 with a remainder of 244.
The number 9 becomes the next digit in our result. 
Result so far: 200947.396039
If we take 3636 away from 3880, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 15:
If we divide 2440 by 404, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 200947.3960396
Deduct 2424 from 2440 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 16:
If we divide 160 by 404, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 200947.3960396
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 200947.3960396 with a remainder of 1.6e-07.
