86016780 ÷ 853 
The aim is to understand the frequency of 853 in 86016780.

Let's proceed to step 1:
The number 853 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 853

On to step 2:
If we divide 86 by 853, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (0) from the dividend after 86, then repeat: 860 / 853

Advancing to step 3:
860 divided by 853 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 853 from 860 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 853

Moving on to step 4:
If we divide 71 by 853, we get 0 and a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 71 after subtracting 0 from 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 853

Going ahead to step 5:
716 divided by 853 is 0 with a remainder of 716.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Subtracting 0 from 716 leaves us with 716.
Include the next digit (7) from the dividend after 716, then repeat: 7167 / 853

Advancing to step 6:
The number 853 fits into 7167 8 times, leaving a remainder of 343.
Write down 8 as next digit of the result. 
Result so far: 1008.0
Subtracting 6824 from 7167 leaves us with 343.
Take the next digit (8) from the dividend and append it to 343, then repeat: 3438 / 853

Going ahead to step 7:
If we divide 3438 by 853, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 10084.0
Subtract 3412 from 3438 to get 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 853

Moving on to step 8:
260 divided by 853 is 0 with a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 100840.0
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 9:
When dividing 2600 by 853, we get 3 with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 100840.3
Subtract 2559 from 2600 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 10:
853 goes into 410 0 times with a remainder of 410.
Use 0 as the next digit of our solution. 
Result so far: 100840.3
Subtracting 0 from 410 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 11:
853 goes into 4100 4 times with a remainder of 688.
The next digit of our result is 4. 
Result so far: 100840.304
If we take 3412 away from 4100, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Moving on to step 12:
853 can be fit into 6880 8 times, resulting in a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 100840.3048
Subtracting 6824 from 6880 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
560 divided by 853 is 0 with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 100840.3048
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 14:
853 goes into 5600 6 times with a remainder of 482.
Put 6 as the next digit of the answer. 
Result so far: 100840.304806
The remainder is 482 after subtracting 5118 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 15:
If we divide 4820 by 853, we get 5 and a remainder of 555.
Use 5 as the next digit of our solution. 
Result so far: 100840.3048065
Subtract 4265 from 4820 to get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Let's proceed to step 16:
853 goes into 5550 6 times with a remainder of 432.
Use 6 as the next digit of our solution. 
Result so far: 100840.30480656
The remainder is 432 after subtracting 5118 from 5550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

The quotient of the division is 100840.30480656, and the remainder is 4.32e-07.
