We're dividing 1801440 by 235 
The aim is to understand the frequency of 235 in 1801440.

Advancing to step 1:
235 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 235

Advancing to step 2:
18 divided by 235 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 235

Moving on to step 3:
When dividing 180 by 235, we get 0 with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 180 to get 180.
Bring next digit (1) of the dividend behind the 180 and repeat the process: 1801 / 235

Going ahead to step 4:
If we divide 1801 by 235, we get 7 and a remainder of 156.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 156 after subtracting 1645 from 1801.
Bring next digit (4) of the dividend behind the 156 and repeat the process: 1564 / 235

Going ahead to step 5:
1564 divided by 235 is 6 with a remainder of 154.
The next digit of our result is 6. 
Result so far: 76.0
Subtracting 1410 from 1564 leaves us with 154.
Include the next digit (4) from the dividend after 154, then repeat: 1544 / 235

Moving on to step 6:
The number 235 fits into 1544 6 times, leaving a remainder of 134.
The next digit of our result is 6. 
Result so far: 766.0
Subtracting 1410 from 1544 leaves us with 134.
Grab the next digit (0) from the dividend, add it to 134, then carry on: 1340 / 235

Step 7:
When dividing 1340 by 235, we get 5 with a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 7665.0
Subtract 1175 from 1340 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 8:
When dividing 1650 by 235, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 7665.7
Subtracting 1645 from 1650 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
The number 235 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7665.7
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
500 divided by 235 is 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 7665.702
The remainder is 30 after subtracting 470 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 235 fits into 300 1 times, leaving a remainder of 65.
The next digit of our result is 1. 
Result so far: 7665.7021
Deduct 235 from 300 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 12:
If we divide 650 by 235, we get 2 and a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 7665.70212
If we take 470 away from 650, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 13:
If we divide 1800 by 235, we get 7 and a remainder of 155.
The next digit of our result is 7. 
Result so far: 7665.702127
Subtract 1645 from 1800 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.

Advancing to step 14:
235 can be fit into 1550 6 times, resulting in a remainder of 140.
The next digit of our result is 6. 
Result so far: 7665.7021276
If we subtract 1410 from 1550, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 15:
1400 divided by 235 is 5 with a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 7665.70212765
Subtract 1175 from 1400 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The quotient of the division is 7665.70212765, and the remainder is 2.25e-07.
