40721019 divided by 75 
The aim is to understand the frequency of 75 in 40721019.

Going ahead to step 1:
75 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 75

On to step 2:
75 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 75

Advancing to step 3:
The number 75 fits into 407 5 times, leaving a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 32 after subtracting 375 from 407.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 75

Advancing to step 4:
75 goes into 322 4 times with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Deduct 300 from 322 and we're left with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 75

Moving on to step 5:
When dividing 221 by 75, we get 2 with a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 542.0
The remainder is 71 after subtracting 150 from 221.
Fetch the next digit (0) from the dividend, attach it to 71 and continue: 710 / 75

On to step 6:
The number 75 fits into 710 9 times, leaving a remainder of 35.
The next digit of our result is 9. 
Result so far: 5429.0
Subtracting 675 from 710 leaves us with 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 75

Going ahead to step 7:
If we divide 351 by 75, we get 4 and a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 54294.0
The remainder is 51 after subtracting 300 from 351.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 75

Going ahead to step 8:
The number 75 fits into 519 6 times, leaving a remainder of 69.
Use 6 as the next digit of our solution. 
Result so far: 542946.0
The remainder is 69 after subtracting 450 from 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
75 goes into 690 9 times with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 542946.9
Subtracting 675 from 690 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
The number 75 fits into 150 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 542946.92
The remainder is 0 after subtracting 150 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
If we divide 0 by 75, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 542946.92
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 542946.92
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 542946.92 and a remainder of 0.0.
