We divide 18554559 by 853
The aim is to understand the frequency of 853 in 18554559.

Step 1:
When dividing 1 by 853, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 853

On to step 2:
If we divide 18 by 853, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 853

Moving on to step 3:
853 goes into 185 0 times with a remainder of 185.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 185 and we're left with 185.
Append the next digit (5) from the dividend to 185 and continue with: 1855 / 853

On to step 4:
The number 853 fits into 1855 2 times, leaving a remainder of 149.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1706 from 1855 leaves us with 149.
Include the next digit (4) from the dividend after 149, then repeat: 1494 / 853

On to step 5:
The number 853 fits into 1494 1 times, leaving a remainder of 641.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 853 from 1494 and we're left with 641.
Append the next digit (5) from the dividend to 641 and continue with: 6415 / 853

Advancing to step 6:
6415 divided by 853 is 7 with a remainder of 444.
Use 7 as the next digit of our solution. 
Result so far: 217.0
Subtract 5971 from 6415 to get 444.
Take the next digit (5) from the dividend and append it to 444, then repeat: 4445 / 853

Let's proceed to step 7:
853 can be fit into 4445 5 times, resulting in a remainder of 180.
The number 5 becomes the next digit in our result. 
Result so far: 2175.0
If we subtract 4265 from 4445, we get 180.
Bring next digit (9) of the dividend behind the 180 and repeat the process: 1809 / 853

Advancing to step 8:
1809 divided by 853 is 2 with a remainder of 103.
Write down 2 as next digit of the result. 
Result so far: 21752.0
If we subtract 1706 from 1809, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 9:
When dividing 1030 by 853, we get 1 with a remainder of 177.
Write down 1 as next digit of the result. 
Result so far: 21752.1
Deduct 853 from 1030 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 10:
The number 853 fits into 1770 2 times, leaving a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 21752.12
Subtract 1706 from 1770 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
853 goes into 640 0 times with a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 21752.12
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 12:
853 goes into 6400 7 times with a remainder of 429.
The next digit of our result is 7. 
Result so far: 21752.1207
If we subtract 5971 from 6400, we get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 13:
If we divide 4290 by 853, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 21752.12075
Subtract 4265 from 4290 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 14:
If we divide 250 by 853, we get 0 and a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 21752.12075
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 15:
The number 853 fits into 2500 2 times, leaving a remainder of 794.
The next digit of our result is 2. 
Result so far: 21752.1207502
Subtracting 1706 from 2500 leaves us with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

On to step 16:
If we divide 7940 by 853, we get 9 and a remainder of 263.
Use 9 as the next digit of our solution. 
Result so far: 21752.12075029
If we take 7677 away from 7940, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

The final outcome is 21752.12075029, with a leftover of 2.63e-07.
