Let's divide 72535978 by 435
The aim is to understand the frequency of 435 in 72535978.

Let's proceed to step 1:
If we divide 7 by 435, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 435

Let's proceed to step 2:
435 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (5) from the dividend after 72, then repeat: 725 / 435

Advancing to step 3:
725 divided by 435 is 1 with a remainder of 290.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 435 from 725 to get 290.
Bring next digit (3) of the dividend behind the 290 and repeat the process: 2903 / 435

Going ahead to step 4:
435 goes into 2903 6 times with a remainder of 293.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 293 after subtracting 2610 from 2903.
Grab the next digit (5) from the dividend, add it to 293, then carry on: 2935 / 435

Going ahead to step 5:
If we divide 2935 by 435, we get 6 and a remainder of 325.
Write down 6 as next digit of the result. 
Result so far: 166.0
If we subtract 2610 from 2935, we get 325.
Fetch the next digit (9) from the dividend, attach it to 325 and continue: 3259 / 435

Going ahead to step 6:
435 goes into 3259 7 times with a remainder of 214.
The number 7 becomes the next digit in our result. 
Result so far: 1667.0
Deduct 3045 from 3259 and we're left with 214.
Include the next digit (7) from the dividend after 214, then repeat: 2147 / 435

Going ahead to step 7:
When dividing 2147 by 435, we get 4 with a remainder of 407.
Write down 4 as next digit of the result. 
Result so far: 16674.0
If we take 1740 away from 2147, we end up with 407.
Include the next digit (8) from the dividend after 407, then repeat: 4078 / 435

Let's proceed to step 8:
If we divide 4078 by 435, we get 9 and a remainder of 163.
Record the quotient 9 as the next digit in the result. 
Result so far: 166749.0
Subtract 3915 from 4078 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 9:
435 goes into 1630 3 times with a remainder of 325.
The number 3 becomes the next digit in our result. 
Result so far: 166749.3
If we take 1305 away from 1630, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 10:
If we divide 3250 by 435, we get 7 and a remainder of 205.
The next digit of our result is 7. 
Result so far: 166749.37
If we subtract 3045 from 3250, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 11:
435 goes into 2050 4 times with a remainder of 310.
The next digit of our result is 4. 
Result so far: 166749.374
Subtract 1740 from 2050 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 12:
When dividing 3100 by 435, we get 7 with a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 166749.3747
Subtracting 3045 from 3100 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
435 can be fit into 550 1 times, resulting in a remainder of 115.
The next digit of our result is 1. 
Result so far: 166749.37471
If we subtract 435 from 550, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 14:
The number 435 fits into 1150 2 times, leaving a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 166749.374712
If we subtract 870 from 1150, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 15:
When dividing 2800 by 435, we get 6 with a remainder of 190.
Put 6 as the next digit of the answer. 
Result so far: 166749.3747126
If we subtract 2610 from 2800, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 16:
If we divide 1900 by 435, we get 4 and a remainder of 160.
Write down 4 as next digit of the result. 
Result so far: 166749.37471264
If we subtract 1740 from 1900, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 166749.37471264, and the remainder is 1.6e-07.
