We look at the division of 745370 by 53 
The aim is to understand the frequency of 53 in 745370.

Moving on to step 1:
53 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 53

Let's proceed to step 2:
53 can be fit into 74 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 53 from 74 leaves us with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 53

On to step 3:
When dividing 215 by 53, we get 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 212 from 215 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 53

Moving on to step 4:
53 can be fit into 33 0 times, resulting in a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 140.0
Subtracting 0 from 33 leaves us with 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 53

Advancing to step 5:
If we divide 337 by 53, we get 6 and a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 1406.0
Subtracting 318 from 337 leaves us with 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 53

Let's proceed to step 6:
When dividing 190 by 53, we get 3 with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 14063.0
The remainder is 31 after subtracting 159 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
53 can be fit into 310 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 14063.5
If we subtract 265 from 310, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 8:
The number 53 fits into 450 8 times, leaving a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 14063.58
If we take 424 away from 450, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
260 divided by 53 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 14063.584
Subtract 212 from 260 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
When dividing 480 by 53, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 14063.5849
If we subtract 477 from 480, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
When dividing 30 by 53, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 14063.5849
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
When dividing 300 by 53, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 14063.584905
Deduct 265 from 300 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
If we divide 350 by 53, we get 6 and a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 14063.5849056
Subtracting 318 from 350 leaves us 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.

Step 14:
53 can be fit into 320 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 14063.58490566
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.

After the division, we end up with 14063.58490566 and a remainder of 2e-09.
