We divide 54542989 by 435
The aim is to understand the frequency of 435 in 54542989.

On to step 1:
If we divide 5 by 435, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 435

Moving on to step 2:
435 can be fit into 54 0 times, resulting in a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 435

Let's proceed to step 3:
The number 435 fits into 545 1 times, leaving a remainder of 110.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 435 from 545 leaves us with 110.
Include the next digit (4) from the dividend after 110, then repeat: 1104 / 435

Let's proceed to step 4:
The number 435 fits into 1104 2 times, leaving a remainder of 234.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 234 after subtracting 870 from 1104.
Bring next digit (2) of the dividend behind the 234 and repeat the process: 2342 / 435

Moving on to step 5:
If we divide 2342 by 435, we get 5 and a remainder of 167.
The next digit of our result is 5. 
Result so far: 125.0
If we take 2175 away from 2342, we end up with 167.
Grab the next digit (9) from the dividend, add it to 167, then carry on: 1679 / 435

On to step 6:
If we divide 1679 by 435, we get 3 and a remainder of 374.
Use 3 as the next digit of our solution. 
Result so far: 1253.0
The remainder is 374 after subtracting 1305 from 1679.
Include the next digit (8) from the dividend after 374, then repeat: 3748 / 435

Advancing to step 7:
The number 435 fits into 3748 8 times, leaving a remainder of 268.
The next digit of our result is 8. 
Result so far: 12538.0
Deduct 3480 from 3748 and we're left with 268.
Bring next digit (9) of the dividend behind the 268 and repeat the process: 2689 / 435

On to step 8:
435 can be fit into 2689 6 times, resulting in a remainder of 79.
Record the quotient 6 as the next digit in the result. 
Result so far: 125386.0
If we subtract 2610 from 2689, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 9:
435 can be fit into 790 1 times, resulting in a remainder of 355.
The number 1 becomes the next digit in our result. 
Result so far: 125386.1
Subtract 435 from 790 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 10:
When dividing 3550 by 435, we get 8 with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 125386.18
Deduct 3480 from 3550 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
700 divided by 435 is 1 with a remainder of 265.
The next digit of our result is 1. 
Result so far: 125386.181
If we take 435 away from 700, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 12:
2650 divided by 435 is 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 125386.1816
If we subtract 2610 from 2650, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
When dividing 400 by 435, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 125386.1816
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 14:
The number 435 fits into 4000 9 times, leaving a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 125386.181609
If we take 3915 away from 4000, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 15:
When dividing 850 by 435, we get 1 with a remainder of 415.
The next digit of our result is 1. 
Result so far: 125386.1816091
The remainder is 415 after subtracting 435 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 16:
435 can be fit into 4150 9 times, resulting in a remainder of 235.
The number 9 becomes the next digit in our result. 
Result so far: 125386.18160919
If we take 3915 away from 4150, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Our division results in 125386.18160919 with a remaining 2.35e-07.
