Let's divide 2515143 by 975
The aim is to understand the frequency of 975 in 2515143.

Going ahead to step 1:
2 divided by 975 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 975

Advancing to step 2:
975 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 975

On to step 3:
251 divided by 975 is 0 with a remainder of 251.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 251, we end up with 251.
Append the next digit (5) from the dividend to 251 and continue with: 2515 / 975

Moving on to step 4:
If we divide 2515 by 975, we get 2 and a remainder of 565.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1950 from 2515 to get 565.
Append the next digit (1) from the dividend to 565 and continue with: 5651 / 975

Advancing to step 5:
975 goes into 5651 5 times with a remainder of 776.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 4875 from 5651 and we're left with 776.
Grab the next digit (4) from the dividend, add it to 776, then carry on: 7764 / 975

On to step 6:
975 can be fit into 7764 7 times, resulting in a remainder of 939.
Record the quotient 7 as the next digit in the result. 
Result so far: 257.0
Subtract 6825 from 7764 to get 939.
Append the next digit (3) from the dividend to 939 and continue with: 9393 / 975

Advancing to step 7:
975 goes into 9393 9 times with a remainder of 618.
Use 9 as the next digit of our solution. 
Result so far: 2579.0
Subtract 8775 from 9393 to get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Step 8:
975 can be fit into 6180 6 times, resulting in a remainder of 330.
Use 6 as the next digit of our solution. 
Result so far: 2579.6
The remainder is 330 after subtracting 5850 from 6180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 9:
When dividing 3300 by 975, we get 3 with a remainder of 375.
The next digit of our result is 3. 
Result so far: 2579.63
If we take 2925 away from 3300, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 10:
3750 divided by 975 is 3 with a remainder of 825.
Use 3 as the next digit of our solution. 
Result so far: 2579.633
The remainder is 825 after subtracting 2925 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

The final outcome is 2579.633, with a leftover of 0.0825.
