43763404 ÷ 53 
The aim is to understand the frequency of 53 in 43763404.

On to step 1:
The number 53 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 53

Step 2:
The number 53 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 53

Moving on to step 3:
437 divided by 53 is 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 13 after subtracting 424 from 437.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 53

On to step 4:
The number 53 fits into 136 2 times, leaving a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtracting 106 from 136 leaves us with 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 53

Let's proceed to step 5:
53 goes into 303 5 times with a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 825.0
If we take 265 away from 303, we end up with 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 53

Going ahead to step 6:
384 divided by 53 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 8257.0
Subtract 371 from 384 to get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 53

Let's proceed to step 7:
53 can be fit into 130 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 82572.0
Subtract 106 from 130 to get 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 53

On to step 8:
53 can be fit into 244 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 825724.0
Deduct 212 from 244 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
53 can be fit into 320 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 825724.6
Subtract 318 from 320 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
53 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 825724.6
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
The number 53 fits into 200 3 times, leaving a remainder of 41.
The next digit of our result is 3. 
Result so far: 825724.603
Subtract 159 from 200 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 12:
410 divided by 53 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 825724.6037
Subtracting 371 from 410 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
390 divided by 53 is 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 825724.60377
Subtract 371 from 390 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 825724.60377 and a remainder of 1.9e-05.
