We look at the division of 53160 by 37 
The aim is to understand the frequency of 37 in 53160.

Let's proceed to step 1:
When dividing 5 by 37, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 37

Step 2:
37 goes into 53 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 37 away from 53, we end up with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 37

Going ahead to step 3:
When dividing 161 by 37, we get 4 with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 148 from 161, we get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 37

Let's proceed to step 4:
When dividing 136 by 37, we get 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 143.0
Subtract 111 from 136 to get 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 37

Let's proceed to step 5:
37 can be fit into 250 6 times, resulting in a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 1436.0
If we subtract 222 from 250, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 6:
37 can be fit into 280 7 times, resulting in a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 1436.7
The remainder is 21 after subtracting 259 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
37 goes into 210 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1436.75
If we take 185 away from 210, 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.

Going ahead to step 8:
If we divide 250 by 37, we get 6 and a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 1436.756
Deduct 222 from 250 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
37 can be fit into 280 7 times, resulting in a remainder of 21.
The next digit of our result is 7. 
Result so far: 1436.7567
Subtracting 259 from 280 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
If we divide 210 by 37, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1436.75675
Subtract 185 from 210 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.

Moving on to step 11:
When dividing 250 by 37, we get 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 1436.756756
The remainder is 28 after subtracting 222 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
280 divided by 37 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 1436.7567567
Subtracting 259 from 280 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
The number 37 fits into 210 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1436.75675675
Subtracting 185 from 210 leaves us 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.

The final outcome is 1436.75675675, with a leftover of 2.5e-08.
