We divide 724645 by 53
The aim is to understand the frequency of 53 in 724645.

Advancing to step 1:
If we divide 7 by 53, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 53

On to step 2:
When dividing 72 by 53, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 53 from 72 and we're left with 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 53

On to step 3:
53 can be fit into 194 3 times, resulting in a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 159 from 194 and we're left with 35.
Bring next digit (6) of the dividend behind the 35 and repeat the process: 356 / 53

Step 4:
356 divided by 53 is 6 with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
If we take 318 away from 356, we end up with 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 53

Going ahead to step 5:
53 can be fit into 384 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 1367.0
Subtracting 371 from 384 leaves us with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 53

On to step 6:
When dividing 135 by 53, we get 2 with a remainder of 29.
The next digit of our result is 2. 
Result so far: 13672.0
Deduct 106 from 135 and we're left 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.

Going ahead to step 7:
The number 53 fits into 290 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 13672.5
Subtract 265 from 290 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
The number 53 fits into 250 4 times, leaving a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 13672.54
Deduct 212 from 250 and we're left 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 9:
When dividing 380 by 53, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 13672.547
The remainder is 9 after subtracting 371 from 380.
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 10:
The number 53 fits into 90 1 times, leaving a remainder of 37.
The next digit of our result is 1. 
Result so far: 13672.5471
Deduct 53 from 90 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 11:
The number 53 fits into 370 6 times, leaving a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 13672.54716
The remainder is 52 after subtracting 318 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
The number 53 fits into 520 9 times, leaving a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 13672.547169
If we take 477 away from 520, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
53 can be fit into 430 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 13672.5471698
The remainder is 6 after subtracting 424 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
When dividing 60 by 53, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 13672.54716981
If we subtract 53 from 60, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 13672.54716981 and a remainder of 7e-09.
