Let's divide 85400663 by 435
The aim is to understand the frequency of 435 in 85400663.

Step 1:
435 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 435

On to step 2:
When dividing 85 by 435, we get 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Take the next digit (4) from the dividend and append it to 85, then repeat: 854 / 435

Let's proceed to step 3:
435 goes into 854 1 times with a remainder of 419.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 435 away from 854, we end up with 419.
Append the next digit (0) from the dividend to 419 and continue with: 4190 / 435

Going ahead to step 4:
435 goes into 4190 9 times with a remainder of 275.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 3915 from 4190 leaves us with 275.
Grab the next digit (0) from the dividend, add it to 275, then carry on: 2750 / 435

On to step 5:
435 can be fit into 2750 6 times, resulting in a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
Subtract 2610 from 2750 to get 140.
Bring next digit (6) of the dividend behind the 140 and repeat the process: 1406 / 435

Step 6:
435 can be fit into 1406 3 times, resulting in a remainder of 101.
Put 3 as the next digit of the answer. 
Result so far: 1963.0
The remainder is 101 after subtracting 1305 from 1406.
Append the next digit (6) from the dividend to 101 and continue with: 1016 / 435

Advancing to step 7:
The number 435 fits into 1016 2 times, leaving a remainder of 146.
Use 2 as the next digit of our solution. 
Result so far: 19632.0
If we take 870 away from 1016, we end up with 146.
Include the next digit (3) from the dividend after 146, then repeat: 1463 / 435

Going ahead to step 8:
1463 divided by 435 is 3 with a remainder of 158.
The next digit of our result is 3. 
Result so far: 196323.0
The remainder is 158 after subtracting 1305 from 1463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 9:
1580 divided by 435 is 3 with a remainder of 275.
Put 3 as the next digit of the answer. 
Result so far: 196323.3
Deduct 1305 from 1580 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 10:
435 goes into 2750 6 times with a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 196323.36
Deduct 2610 from 2750 and we're left 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.

Going ahead to step 11:
435 goes into 1400 3 times with a remainder of 95.
The number 3 becomes the next digit in our result. 
Result so far: 196323.363
Subtract 1305 from 1400 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 12:
If we divide 950 by 435, we get 2 and a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 196323.3632
Subtracting 870 from 950 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
When dividing 800 by 435, we get 1 with a remainder of 365.
The number 1 becomes the next digit in our result. 
Result so far: 196323.36321
Subtracting 435 from 800 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 14:
When dividing 3650 by 435, we get 8 with a remainder of 170.
Write down 8 as next digit of the result. 
Result so far: 196323.363218
Subtracting 3480 from 3650 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 15:
If we divide 1700 by 435, we get 3 and a remainder of 395.
Record the quotient 3 as the next digit in the result. 
Result so far: 196323.3632183
If we subtract 1305 from 1700, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 16:
The number 435 fits into 3950 9 times, leaving a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 196323.36321839
If we subtract 3915 from 3950, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 196323.36321839, and the remainder is 3.5e-08.
