Let's divide 77659854 by 853
The aim is to understand the frequency of 853 in 77659854.

Going ahead to step 1:
7 divided by 853 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 853

Moving on to step 2:
When dividing 77 by 853, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 853

Going ahead to step 3:
If we divide 776 by 853, we get 0 and a remainder of 776.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 776, we get 776.
Take the next digit (5) from the dividend and append it to 776, then repeat: 7765 / 853

On to step 4:
853 goes into 7765 9 times with a remainder of 88.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 88 after subtracting 7677 from 7765.
Append the next digit (9) from the dividend to 88 and continue with: 889 / 853

Step 5:
When dividing 889 by 853, we get 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we take 853 away from 889, we end up with 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 853

Step 6:
When dividing 368 by 853, we get 0 with a remainder of 368.
Record the quotient 0 as the next digit in the result. 
Result so far: 910.0
If we subtract 0 from 368, we get 368.
Take the next digit (5) from the dividend and append it to 368, then repeat: 3685 / 853

Let's proceed to step 7:
3685 divided by 853 is 4 with a remainder of 273.
The next digit of our result is 4. 
Result so far: 9104.0
Deduct 3412 from 3685 and we're left with 273.
Include the next digit (4) from the dividend after 273, then repeat: 2734 / 853

On to step 8:
When dividing 2734 by 853, we get 3 with a remainder of 175.
The number 3 becomes the next digit in our result. 
Result so far: 91043.0
Subtract 2559 from 2734 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 9:
When dividing 1750 by 853, we get 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 91043.2
The remainder is 44 after subtracting 1706 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
440 divided by 853 is 0 with a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 91043.2
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 11:
The number 853 fits into 4400 5 times, leaving a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 91043.205
If we take 4265 away from 4400, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 12:
853 can be fit into 1350 1 times, resulting in a remainder of 497.
Use 1 as the next digit of our solution. 
Result so far: 91043.2051
The remainder is 497 after subtracting 853 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Let's proceed to step 13:
853 can be fit into 4970 5 times, resulting in a remainder of 705.
Use 5 as the next digit of our solution. 
Result so far: 91043.20515
Subtract 4265 from 4970 to get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Step 14:
853 can be fit into 7050 8 times, resulting in a remainder of 226.
Put 8 as the next digit of the answer. 
Result so far: 91043.205158
The remainder is 226 after subtracting 6824 from 7050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 15:
2260 divided by 853 is 2 with a remainder of 554.
The number 2 becomes the next digit in our result. 
Result so far: 91043.2051582
Deduct 1706 from 2260 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Step 16:
The number 853 fits into 5540 6 times, leaving a remainder of 422.
The number 6 becomes the next digit in our result. 
Result so far: 91043.20515826
Deduct 5118 from 5540 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

The quotient of the division is 91043.20515826, and the remainder is 4.22e-07.
