We're dividing 37215549 by 965 
The aim is to understand the frequency of 965 in 37215549.

Let's proceed to step 1:
965 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 965

Step 2:
37 divided by 965 is 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 965

On to step 3:
372 divided by 965 is 0 with a remainder of 372.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 372, we end up with 372.
Append the next digit (1) from the dividend to 372 and continue with: 3721 / 965

Moving on to step 4:
965 goes into 3721 3 times with a remainder of 826.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2895 from 3721 and we're left with 826.
Include the next digit (5) from the dividend after 826, then repeat: 8265 / 965

Advancing to step 5:
The number 965 fits into 8265 8 times, leaving a remainder of 545.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 7720 from 8265 to get 545.
Grab the next digit (5) from the dividend, add it to 545, then carry on: 5455 / 965

Step 6:
5455 divided by 965 is 5 with a remainder of 630.
Put 5 as the next digit of the answer. 
Result so far: 385.0
Deduct 4825 from 5455 and we're left with 630.
Take the next digit (4) from the dividend and append it to 630, then repeat: 6304 / 965

Advancing to step 7:
965 can be fit into 6304 6 times, resulting in a remainder of 514.
Put 6 as the next digit of the answer. 
Result so far: 3856.0
Subtracting 5790 from 6304 leaves us with 514.
Bring next digit (9) of the dividend behind the 514 and repeat the process: 5149 / 965

Step 8:
5149 divided by 965 is 5 with a remainder of 324.
The number 5 becomes the next digit in our result. 
Result so far: 38565.0
Subtracting 4825 from 5149 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 9:
When dividing 3240 by 965, we get 3 with a remainder of 345.
Write down 3 as next digit of the result. 
Result so far: 38565.3
Deduct 2895 from 3240 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Advancing to step 10:
3450 divided by 965 is 3 with a remainder of 555.
The next digit of our result is 3. 
Result so far: 38565.33
Subtract 2895 from 3450 to get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Our division results in 38565.33 with a remaining 0.555.
