743223 ÷ 53 
The aim is to understand the frequency of 53 in 743223.

Let's proceed to step 1:
7 divided by 53 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 53

On to step 2:
53 can be fit into 74 1 times, resulting in a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 53 away from 74, we end up with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 53

On to step 3:
53 goes into 213 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 212 from 213 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 53

Moving on to step 4:
53 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Subtract 0 from 12 to get 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 53

Moving on to step 5:
122 divided by 53 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 1402.0
The remainder is 16 after subtracting 106 from 122.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 53

Going ahead to step 6:
If we divide 163 by 53, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 14023.0
If we take 159 away from 163, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
53 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 14023.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
53 can be fit into 400 7 times, resulting in a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 14023.07
Subtracting 371 from 400 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
53 can be fit into 290 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 14023.075
If we take 265 away from 290, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
If we divide 250 by 53, we get 4 and a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 14023.0754
If we take 212 away from 250, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
The number 53 fits into 380 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 14023.07547
If we subtract 371 from 380, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
If we divide 90 by 53, we get 1 and a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 14023.075471
Subtract 53 from 90 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 13:
53 goes into 370 6 times with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 14023.0754716
Subtract 318 from 370 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 14:
If we divide 520 by 53, we get 9 and a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 14023.07547169
If we subtract 477 from 520, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The quotient of the division is 14023.07547169, and the remainder is 4.3e-08.
