3540004 divided by 853 
The aim is to understand the frequency of 853 in 3540004.

Step 1:
When dividing 3 by 853, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 853

Advancing to step 2:
If we divide 35 by 853, we get 0 and a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 853

Step 3:
354 divided by 853 is 0 with a remainder of 354.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 354 to get 354.
Grab the next digit (0) from the dividend, add it to 354, then carry on: 3540 / 853

Moving on to step 4:
853 goes into 3540 4 times with a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3412 away from 3540, we end up with 128.
Grab the next digit (0) from the dividend, add it to 128, then carry on: 1280 / 853

Moving on to step 5:
853 can be fit into 1280 1 times, resulting in a remainder of 427.
Use 1 as the next digit of our solution. 
Result so far: 41.0
The remainder is 427 after subtracting 853 from 1280.
Bring next digit (0) of the dividend behind the 427 and repeat the process: 4270 / 853

Moving on to step 6:
When dividing 4270 by 853, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 415.0
If we subtract 4265 from 4270, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 853

Step 7:
When dividing 54 by 853, we get 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 4150.0
If we subtract 0 from 54, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
If we divide 540 by 853, we get 0 and a remainder of 540.
Use 0 as the next digit of our solution. 
Result so far: 4150.0
If we subtract 0 from 540, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 9:
5400 divided by 853 is 6 with a remainder of 282.
Put 6 as the next digit of the answer. 
Result so far: 4150.06
If we subtract 5118 from 5400, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 10:
The number 853 fits into 2820 3 times, leaving a remainder of 261.
Put 3 as the next digit of the answer. 
Result so far: 4150.063
Deduct 2559 from 2820 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 11:
853 goes into 2610 3 times with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 4150.0633
If we subtract 2559 from 2610, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 4150.0633 with a remainder of 0.00051.
