We're dividing 44877779 by 853 
The aim is to understand the frequency of 853 in 44877779.

Let's proceed to step 1:
853 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 853

Moving on to step 2:
The number 853 fits into 44 0 times, leaving a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 853

Step 3:
If we divide 448 by 853, we get 0 and a remainder of 448.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 448, we end up with 448.
Append the next digit (7) from the dividend to 448 and continue with: 4487 / 853

Step 4:
853 can be fit into 4487 5 times, resulting in a remainder of 222.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 4265 from 4487 leaves us with 222.
Bring next digit (7) of the dividend behind the 222 and repeat the process: 2227 / 853

Going ahead to step 5:
853 goes into 2227 2 times with a remainder of 521.
The next digit of our result is 2. 
Result so far: 52.0
Subtract 1706 from 2227 to get 521.
Take the next digit (7) from the dividend and append it to 521, then repeat: 5217 / 853

Let's proceed to step 6:
853 can be fit into 5217 6 times, resulting in a remainder of 99.
The next digit of our result is 6. 
Result so far: 526.0
The remainder is 99 after subtracting 5118 from 5217.
Bring next digit (7) of the dividend behind the 99 and repeat the process: 997 / 853

Advancing to step 7:
The number 853 fits into 997 1 times, leaving a remainder of 144.
Record the quotient 1 as the next digit in the result. 
Result so far: 5261.0
If we subtract 853 from 997, we get 144.
Append the next digit (9) from the dividend to 144 and continue with: 1449 / 853

Moving on to step 8:
If we divide 1449 by 853, we get 1 and a remainder of 596.
Use 1 as the next digit of our solution. 
Result so far: 52611.0
If we take 853 away from 1449, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Moving on to step 9:
853 goes into 5960 6 times with a remainder of 842.
Use 6 as the next digit of our solution. 
Result so far: 52611.6
The remainder is 842 after subtracting 5118 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Let's proceed to step 10:
If we divide 8420 by 853, we get 9 and a remainder of 743.
Put 9 as the next digit of the answer. 
Result so far: 52611.69
Deduct 7677 from 8420 and we're left with 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Advancing to step 11:
When dividing 7430 by 853, we get 8 with a remainder of 606.
The number 8 becomes the next digit in our result. 
Result so far: 52611.698
The remainder is 606 after subtracting 6824 from 7430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Going ahead to step 12:
853 goes into 6060 7 times with a remainder of 89.
Use 7 as the next digit of our solution. 
Result so far: 52611.6987
Subtracting 5971 from 6060 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 13:
If we divide 890 by 853, we get 1 and a remainder of 37.
The next digit of our result is 1. 
Result so far: 52611.69871
If we subtract 853 from 890, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 14:
853 goes into 370 0 times with a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 52611.69871
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 15:
3700 divided by 853 is 4 with a remainder of 288.
The number 4 becomes the next digit in our result. 
Result so far: 52611.6987104
If we take 3412 away from 3700, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 16:
If we divide 2880 by 853, we get 3 and a remainder of 321.
Use 3 as the next digit of our solution. 
Result so far: 52611.69871043
Subtracting 2559 from 2880 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

The final outcome is 52611.69871043, with a leftover of 3.21e-07.
