37557615 ÷ 53 
The aim is to understand the frequency of 53 in 37557615.

Moving on to step 1:
If we divide 3 by 53, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 53

Going ahead to step 2:
53 can be fit into 37 0 times, resulting in a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 53

Advancing to step 3:
When dividing 375 by 53, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 4 after subtracting 371 from 375.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 53

Going ahead to step 4:
45 divided by 53 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 53

Advancing to step 5:
When dividing 457 by 53, we get 8 with a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 708.0
If we take 424 away from 457, we end up with 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 53

On to step 6:
When dividing 336 by 53, we get 6 with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 7086.0
If we subtract 318 from 336, we get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 53

Advancing to step 7:
If we divide 181 by 53, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 70863.0
Subtract 159 from 181 to get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 53

Going ahead to step 8:
If we divide 225 by 53, we get 4 and a remainder of 13.
The next digit of our result is 4. 
Result so far: 708634.0
Subtracting 212 from 225 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
130 divided by 53 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 708634.2
Subtract 106 from 130 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
The number 53 fits into 240 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 708634.24
The remainder is 28 after subtracting 212 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
When dividing 280 by 53, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 708634.245
Subtracting 265 from 280 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
The number 53 fits into 150 2 times, leaving a remainder of 44.
The next digit of our result is 2. 
Result so far: 708634.2452
Subtract 106 from 150 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
440 divided by 53 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 708634.24528
If we subtract 424 from 440, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
53 goes into 160 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 708634.245283
Subtracting 159 from 160 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 15:
When dividing 10 by 53, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 708634.245283
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 16:
When dividing 100 by 53, we get 1 with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 708634.24528301
Subtract 53 from 100 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 708634.24528301, with a leftover of 4.7e-08.
