Let's divide 903781 by 75
The aim is to understand the frequency of 75 in 903781.

Let's proceed to step 1:
If we divide 9 by 75, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 75

Let's proceed to step 2:
75 goes into 90 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 75 from 90 and we're left with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 75

Going ahead to step 3:
If we divide 153 by 75, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 150 from 153 and we're left with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 75

Going ahead to step 4:
75 goes into 37 0 times with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
The remainder is 37 after subtracting 0 from 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 75

Advancing to step 5:
378 divided by 75 is 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 1205.0
The remainder is 3 after subtracting 375 from 378.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 75

On to step 6:
If we divide 31 by 75, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 12050.0
Subtracting 0 from 31 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
310 divided by 75 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 12050.4
If we take 300 away from 310, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 75, we get 1 and a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 12050.41
Subtract 75 from 100 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.

Step 9:
75 goes into 250 3 times with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 12050.413
If we subtract 225 from 250, we 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.

On to step 10:
When dividing 250 by 75, we get 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 12050.4133
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.

The final outcome is 12050.4133, with a leftover of 0.00025.
