911959 divided by 75 
The aim is to understand the frequency of 75 in 911959.

Step 1:
When dividing 9 by 75, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 75

Advancing to step 2:
The number 75 fits into 91 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 75 from 91 to get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 75

Moving on to step 3:
75 goes into 161 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 150 from 161 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 75

On to step 4:
119 divided by 75 is 1 with a remainder of 44.
The next digit of our result is 1. 
Result so far: 121.0
If we take 75 away from 119, we end up with 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 75

Advancing to step 5:
75 can be fit into 445 5 times, resulting in a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1215.0
If we subtract 375 from 445, we get 70.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 75

Advancing to step 6:
75 can be fit into 709 9 times, resulting in a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 12159.0
If we take 675 away from 709, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
The number 75 fits into 340 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 12159.4
The remainder is 40 after subtracting 300 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
400 divided by 75 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12159.45
Subtract 375 from 400 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 12159.453
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.

On to step 10:
When dividing 250 by 75, we get 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 12159.4533
Subtracting 225 from 250 leaves us 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.

After the division, we end up with 12159.4533 and a remainder of 0.00025.
