We're dividing 53509318 by 416 
The aim is to understand the frequency of 416 in 53509318.

Let's proceed to step 1:
If we divide 5 by 416, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 416

On to step 2:
The number 416 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 416

On to step 3:
416 goes into 535 1 times with a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 416 from 535 and we're left with 119.
Grab the next digit (0) from the dividend, add it to 119, then carry on: 1190 / 416

Moving on to step 4:
The number 416 fits into 1190 2 times, leaving a remainder of 358.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 832 from 1190, we get 358.
Append the next digit (9) from the dividend to 358 and continue with: 3589 / 416

Moving on to step 5:
3589 divided by 416 is 8 with a remainder of 261.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtract 3328 from 3589 to get 261.
Take the next digit (3) from the dividend and append it to 261, then repeat: 2613 / 416

On to step 6:
The number 416 fits into 2613 6 times, leaving a remainder of 117.
Write down 6 as next digit of the result. 
Result so far: 1286.0
If we take 2496 away from 2613, we end up with 117.
Append the next digit (1) from the dividend to 117 and continue with: 1171 / 416

Advancing to step 7:
1171 divided by 416 is 2 with a remainder of 339.
Record the quotient 2 as the next digit in the result. 
Result so far: 12862.0
Subtracting 832 from 1171 leaves us with 339.
Append the next digit (8) from the dividend to 339 and continue with: 3398 / 416

Step 8:
3398 divided by 416 is 8 with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 128628.0
If we subtract 3328 from 3398, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
The number 416 fits into 700 1 times, leaving a remainder of 284.
The number 1 becomes the next digit in our result. 
Result so far: 128628.1
If we take 416 away from 700, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 10:
If we divide 2840 by 416, we get 6 and a remainder of 344.
The number 6 becomes the next digit in our result. 
Result so far: 128628.16
If we take 2496 away from 2840, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 11:
3440 divided by 416 is 8 with a remainder of 112.
The next digit of our result is 8. 
Result so far: 128628.168
The remainder is 112 after subtracting 3328 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 12:
416 goes into 1120 2 times with a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 128628.1682
The remainder is 288 after subtracting 832 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 13:
When dividing 2880 by 416, we get 6 with a remainder of 384.
Put 6 as the next digit of the answer. 
Result so far: 128628.16826
If we subtract 2496 from 2880, 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.

Step 14:
416 goes into 3840 9 times with a remainder of 96.
Record the quotient 9 as the next digit in the result. 
Result so far: 128628.168269
If we subtract 3744 from 3840, we get 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 15:
If we divide 960 by 416, we get 2 and a remainder of 128.
The next digit of our result is 2. 
Result so far: 128628.1682692
The remainder is 128 after subtracting 832 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 16:
416 goes into 1280 3 times with a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 128628.16826923
Subtract 1248 from 1280 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 128628.16826923, with a leftover of 3.2e-08.
