We look at the division of 6135760 by 537 
The aim is to understand the frequency of 537 in 6135760.

Going ahead to step 1:
When dividing 6 by 537, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 537

Step 2:
537 can be fit into 61 0 times, resulting in a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Bring next digit (3) of the dividend behind the 61 and repeat the process: 613 / 537

On to step 3:
613 divided by 537 is 1 with a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 537 from 613, we get 76.
Take the next digit (5) from the dividend and append it to 76, then repeat: 765 / 537

Moving on to step 4:
537 goes into 765 1 times with a remainder of 228.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 537 from 765 leaves us with 228.
Take the next digit (7) from the dividend and append it to 228, then repeat: 2287 / 537

On to step 5:
When dividing 2287 by 537, we get 4 with a remainder of 139.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Subtracting 2148 from 2287 leaves us with 139.
Take the next digit (6) from the dividend and append it to 139, then repeat: 1396 / 537

Step 6:
The number 537 fits into 1396 2 times, leaving a remainder of 322.
Use 2 as the next digit of our solution. 
Result so far: 1142.0
The remainder is 322 after subtracting 1074 from 1396.
Fetch the next digit (0) from the dividend, attach it to 322 and continue: 3220 / 537

Advancing to step 7:
When dividing 3220 by 537, we get 5 with a remainder of 535.
Write down 5 as next digit of the result. 
Result so far: 11425.0
The remainder is 535 after subtracting 2685 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Going ahead to step 8:
5350 divided by 537 is 9 with a remainder of 517.
Use 9 as the next digit of our solution. 
Result so far: 11425.9
The remainder is 517 after subtracting 4833 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Step 9:
When dividing 5170 by 537, we get 9 with a remainder of 337.
The next digit of our result is 9. 
Result so far: 11425.99
Subtracting 4833 from 5170 leaves us with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

The final result is 11425.99 with a remainder of 0.337.
