We're dividing 55496245 by 409 
The aim is to understand the frequency of 409 in 55496245.

Advancing to step 1:
If we divide 5 by 409, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 409

Going ahead to step 2:
409 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 409

Advancing to step 3:
554 divided by 409 is 1 with a remainder of 145.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 409 from 554, we get 145.
Append the next digit (9) from the dividend to 145 and continue with: 1459 / 409

Advancing to step 4:
1459 divided by 409 is 3 with a remainder of 232.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1227 from 1459 and we're left with 232.
Take the next digit (6) from the dividend and append it to 232, then repeat: 2326 / 409

Going ahead to step 5:
2326 divided by 409 is 5 with a remainder of 281.
Write down 5 as next digit of the result. 
Result so far: 135.0
Deduct 2045 from 2326 and we're left with 281.
Append the next digit (2) from the dividend to 281 and continue with: 2812 / 409

Advancing to step 6:
2812 divided by 409 is 6 with a remainder of 358.
Record the quotient 6 as the next digit in the result. 
Result so far: 1356.0
If we take 2454 away from 2812, we end up with 358.
Take the next digit (4) from the dividend and append it to 358, then repeat: 3584 / 409

Advancing to step 7:
When dividing 3584 by 409, we get 8 with a remainder of 312.
Record the quotient 8 as the next digit in the result. 
Result so far: 13568.0
The remainder is 312 after subtracting 3272 from 3584.
Fetch the next digit (5) from the dividend, attach it to 312 and continue: 3125 / 409

Let's proceed to step 8:
If we divide 3125 by 409, we get 7 and a remainder of 262.
The number 7 becomes the next digit in our result. 
Result so far: 135687.0
Subtract 2863 from 3125 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 9:
409 can be fit into 2620 6 times, resulting in a remainder of 166.
The next digit of our result is 6. 
Result so far: 135687.6
Deduct 2454 from 2620 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 10:
1660 divided by 409 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 135687.64
Subtract 1636 from 1660 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
When dividing 240 by 409, we get 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 135687.64
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 12:
The number 409 fits into 2400 5 times, leaving a remainder of 355.
Put 5 as the next digit of the answer. 
Result so far: 135687.6405
Subtract 2045 from 2400 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 13:
409 goes into 3550 8 times with a remainder of 278.
Use 8 as the next digit of our solution. 
Result so far: 135687.64058
Subtracting 3272 from 3550 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 14:
If we divide 2780 by 409, we get 6 and a remainder of 326.
Write down 6 as next digit of the result. 
Result so far: 135687.640586
Subtracting 2454 from 2780 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 15:
The number 409 fits into 3260 7 times, leaving a remainder of 397.
The next digit of our result is 7. 
Result so far: 135687.6405867
If we subtract 2863 from 3260, we get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

On to step 16:
409 can be fit into 3970 9 times, resulting in a remainder of 289.
Put 9 as the next digit of the answer. 
Result so far: 135687.64058679
Subtracting 3681 from 3970 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

The quotient of the division is 135687.64058679, and the remainder is 2.89e-07.
