We look at the division of 53790835 by 853 
The aim is to understand the frequency of 853 in 53790835.

Step 1:
5 divided by 853 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 853

Step 2:
When dividing 53 by 853, we get 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 853

Moving on to step 3:
853 can be fit into 537 0 times, resulting in a remainder of 537.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 537, we end up with 537.
Take the next digit (9) from the dividend and append it to 537, then repeat: 5379 / 853

On to step 4:
If we divide 5379 by 853, we get 6 and a remainder of 261.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 5118 from 5379, we get 261.
Bring next digit (0) of the dividend behind the 261 and repeat the process: 2610 / 853

Step 5:
853 goes into 2610 3 times with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtracting 2559 from 2610 leaves us with 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 853

Going ahead to step 6:
When dividing 518 by 853, we get 0 with a remainder of 518.
Record the quotient 0 as the next digit in the result. 
Result so far: 630.0
Subtract 0 from 518 to get 518.
Bring next digit (3) of the dividend behind the 518 and repeat the process: 5183 / 853

Step 7:
5183 divided by 853 is 6 with a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 6306.0
Subtract 5118 from 5183 to get 65.
Append the next digit (5) from the dividend to 65 and continue with: 655 / 853

On to step 8:
If we divide 655 by 853, we get 0 and a remainder of 655.
Write down 0 as next digit of the result. 
Result so far: 63060.0
The remainder is 655 after subtracting 0 from 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Let's proceed to step 9:
853 can be fit into 6550 7 times, resulting in a remainder of 579.
The number 7 becomes the next digit in our result. 
Result so far: 63060.7
Deduct 5971 from 6550 and we're left with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Advancing to step 10:
853 goes into 5790 6 times with a remainder of 672.
Put 6 as the next digit of the answer. 
Result so far: 63060.76
Subtract 5118 from 5790 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Going ahead to step 11:
853 goes into 6720 7 times with a remainder of 749.
The next digit of our result is 7. 
Result so far: 63060.767
If we take 5971 away from 6720, we end up with 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

Going ahead to step 12:
When dividing 7490 by 853, we get 8 with a remainder of 666.
Record the quotient 8 as the next digit in the result. 
Result so far: 63060.7678
If we take 6824 away from 7490, we end up with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Let's proceed to step 13:
If we divide 6660 by 853, we get 7 and a remainder of 689.
Record the quotient 7 as the next digit in the result. 
Result so far: 63060.76787
The remainder is 689 after subtracting 5971 from 6660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

On to step 14:
853 goes into 6890 8 times with a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 63060.767878
Deduct 6824 from 6890 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 15:
660 divided by 853 is 0 with a remainder of 660.
Write down 0 as next digit of the result. 
Result so far: 63060.767878
Subtracting 0 from 660 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 16:
6600 divided by 853 is 7 with a remainder of 629.
Record the quotient 7 as the next digit in the result. 
Result so far: 63060.76787807
If we subtract 5971 from 6600, we get 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Our division results in 63060.76787807 with a remaining 6.29e-07.
