We divide 870253 by 75
The aim is to understand the frequency of 75 in 870253.

Step 1:
The number 75 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 75

Advancing to step 2:
When dividing 87 by 75, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 75 from 87 and we're left with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 75

On to step 3:
120 divided by 75 is 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 75 from 120, we get 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 75

Moving on to step 4:
The number 75 fits into 452 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 116.0
Subtracting 450 from 452 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 75

On to step 5:
75 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 1160.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 75

On to step 6:
If we divide 253 by 75, we get 3 and a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 11603.0
If we subtract 225 from 253, 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.

Going ahead to step 7:
When dividing 280 by 75, we get 3 with a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 11603.3
If we subtract 225 from 280, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 8:
75 can be fit into 550 7 times, resulting in a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 11603.37
If we take 525 away from 550, 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.

On to step 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 11603.373
Deduct 225 from 250 and we're left 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 10:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 11603.3733
The remainder is 25 after subtracting 225 from 250.
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 result is 11603.3733 with a remainder of 0.00025.
