We divide 53973438 by 524
The aim is to understand the frequency of 524 in 53973438.

Moving on to step 1:
When dividing 5 by 524, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 524

Step 2:
53 divided by 524 is 0 with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 524

Let's proceed to step 3:
If we divide 539 by 524, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 524 from 539 to get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 524

Advancing to step 4:
If we divide 157 by 524, we get 0 and a remainder of 157.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 157, we end up with 157.
Bring next digit (3) of the dividend behind the 157 and repeat the process: 1573 / 524

Moving on to step 5:
When dividing 1573 by 524, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtract 1572 from 1573 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 524

Let's proceed to step 6:
If we divide 14 by 524, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 1030.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 524

Advancing to step 7:
524 can be fit into 143 0 times, resulting in a remainder of 143.
Record the quotient 0 as the next digit in the result. 
Result so far: 10300.0
If we subtract 0 from 143, we get 143.
Fetch the next digit (8) from the dividend, attach it to 143 and continue: 1438 / 524

On to step 8:
1438 divided by 524 is 2 with a remainder of 390.
Put 2 as the next digit of the answer. 
Result so far: 103002.0
Deduct 1048 from 1438 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 9:
524 goes into 3900 7 times with a remainder of 232.
The number 7 becomes the next digit in our result. 
Result so far: 103002.7
If we subtract 3668 from 3900, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 10:
The number 524 fits into 2320 4 times, leaving a remainder of 224.
Write down 4 as next digit of the result. 
Result so far: 103002.74
Subtracting 2096 from 2320 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 11:
If we divide 2240 by 524, we get 4 and a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 103002.744
Subtracting 2096 from 2240 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

After the division, we end up with 103002.744 and a remainder of 0.0144.
