We're dividing 86793143 by 750 
The aim is to understand the frequency of 750 in 86793143.

Step 1:
When dividing 8 by 750, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 750

Going ahead to step 2:
86 divided by 750 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Fetch the next digit (7) from the dividend, attach it to 86 and continue: 867 / 750

Let's proceed to step 3:
867 divided by 750 is 1 with a remainder of 117.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 750 from 867 leaves us with 117.
Take the next digit (9) from the dividend and append it to 117, then repeat: 1179 / 750

Going ahead to step 4:
If we divide 1179 by 750, we get 1 and a remainder of 429.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 429 after subtracting 750 from 1179.
Include the next digit (3) from the dividend after 429, then repeat: 4293 / 750

Step 5:
750 can be fit into 4293 5 times, resulting in a remainder of 543.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Subtract 3750 from 4293 to get 543.
Append the next digit (1) from the dividend to 543 and continue with: 5431 / 750

Let's proceed to step 6:
If we divide 5431 by 750, we get 7 and a remainder of 181.
Write down 7 as next digit of the result. 
Result so far: 1157.0
The remainder is 181 after subtracting 5250 from 5431.
Bring next digit (4) of the dividend behind the 181 and repeat the process: 1814 / 750

On to step 7:
The number 750 fits into 1814 2 times, leaving a remainder of 314.
Put 2 as the next digit of the answer. 
Result so far: 11572.0
If we subtract 1500 from 1814, we get 314.
Append the next digit (3) from the dividend to 314 and continue with: 3143 / 750

Step 8:
750 goes into 3143 4 times with a remainder of 143.
Write down 4 as next digit of the result. 
Result so far: 115724.0
If we take 3000 away from 3143, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 9:
750 goes into 1430 1 times with a remainder of 680.
The next digit of our result is 1. 
Result so far: 115724.1
If we take 750 away from 1430, we end up with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 10:
If we divide 6800 by 750, we get 9 and a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 115724.19
If we subtract 6750 from 6800, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
If we divide 500 by 750, we get 0 and a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 115724.19
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 12:
The number 750 fits into 5000 6 times, leaving a remainder of 500.
The number 6 becomes the next digit in our result. 
Result so far: 115724.1906
The remainder is 500 after subtracting 4500 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 13:
750 goes into 5000 6 times with a remainder of 500.
Use 6 as the next digit of our solution. 
Result so far: 115724.19066
If we take 4500 away from 5000, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 115724.19066, with a leftover of 0.0005.
