We divide 33321728 by 435
The aim is to understand the frequency of 435 in 33321728.

On to step 1:
The number 435 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 435

On to step 2:
If we divide 33 by 435, we get 0 and a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 435

Advancing to step 3:
When dividing 333 by 435, we get 0 with a remainder of 333.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 333 and we're left with 333.
Append the next digit (2) from the dividend to 333 and continue with: 3332 / 435

On to step 4:
The number 435 fits into 3332 7 times, leaving a remainder of 287.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 3045 from 3332, we get 287.
Bring next digit (1) of the dividend behind the 287 and repeat the process: 2871 / 435

Advancing to step 5:
The number 435 fits into 2871 6 times, leaving a remainder of 261.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Deduct 2610 from 2871 and we're left with 261.
Include the next digit (7) from the dividend after 261, then repeat: 2617 / 435

Advancing to step 6:
If we divide 2617 by 435, we get 6 and a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 766.0
If we subtract 2610 from 2617, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 435

Moving on to step 7:
435 goes into 72 0 times with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 7660.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 435

On to step 8:
The number 435 fits into 728 1 times, leaving a remainder of 293.
Use 1 as the next digit of our solution. 
Result so far: 76601.0
If we take 435 away from 728, we end up with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Let's proceed to step 9:
435 goes into 2930 6 times with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 76601.6
If we take 2610 away from 2930, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
If we divide 3200 by 435, we get 7 and a remainder of 155.
Put 7 as the next digit of the answer. 
Result so far: 76601.67
Subtract 3045 from 3200 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 11:
435 goes into 1550 3 times with a remainder of 245.
The number 3 becomes the next digit in our result. 
Result so far: 76601.673
Subtract 1305 from 1550 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 12:
435 goes into 2450 5 times with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 76601.6735
The remainder is 275 after subtracting 2175 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 13:
The number 435 fits into 2750 6 times, leaving a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 76601.67356
If we take 2610 away from 2750, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 14:
When dividing 1400 by 435, we get 3 with a remainder of 95.
The number 3 becomes the next digit in our result. 
Result so far: 76601.673563
The remainder is 95 after subtracting 1305 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 15:
The number 435 fits into 950 2 times, leaving a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 76601.6735632
The remainder is 80 after subtracting 870 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 16:
The number 435 fits into 800 1 times, leaving a remainder of 365.
The next digit of our result is 1. 
Result so far: 76601.67356321
The remainder is 365 after subtracting 435 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

After the division, we end up with 76601.67356321 and a remainder of 3.65e-07.
