Let's divide 75435839 by 742
The aim is to understand the frequency of 742 in 75435839.

Advancing to step 1:
7 divided by 742 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 742

Moving on to step 2:
If we divide 75 by 742, we get 0 and a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 742

Step 3:
If we divide 754 by 742, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 742 from 754 to get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 742

Advancing to step 4:
The number 742 fits into 123 0 times, leaving a remainder of 123.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 123 leaves us with 123.
Bring next digit (5) of the dividend behind the 123 and repeat the process: 1235 / 742

Advancing to step 5:
1235 divided by 742 is 1 with a remainder of 493.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtract 742 from 1235 to get 493.
Bring next digit (8) of the dividend behind the 493 and repeat the process: 4938 / 742

Let's proceed to step 6:
If we divide 4938 by 742, we get 6 and a remainder of 486.
Record the quotient 6 as the next digit in the result. 
Result so far: 1016.0
Subtracting 4452 from 4938 leaves us with 486.
Fetch the next digit (3) from the dividend, attach it to 486 and continue: 4863 / 742

Moving on to step 7:
742 goes into 4863 6 times with a remainder of 411.
Record the quotient 6 as the next digit in the result. 
Result so far: 10166.0
The remainder is 411 after subtracting 4452 from 4863.
Grab the next digit (9) from the dividend, add it to 411, then carry on: 4119 / 742

Going ahead to step 8:
If we divide 4119 by 742, we get 5 and a remainder of 409.
The number 5 becomes the next digit in our result. 
Result so far: 101665.0
If we take 3710 away from 4119, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Going ahead to step 9:
742 can be fit into 4090 5 times, resulting in a remainder of 380.
Write down 5 as next digit of the result. 
Result so far: 101665.5
Subtract 3710 from 4090 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 10:
If we divide 3800 by 742, we get 5 and a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 101665.55
Deduct 3710 from 3800 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 101665.55 and a remainder of 0.09.
