We're dividing 55494993 by 839 
The aim is to understand the frequency of 839 in 55494993.

Step 1:
839 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 839

On to step 2:
839 goes into 55 0 times with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 839

Step 3:
If we divide 554 by 839, we get 0 and a remainder of 554.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 554 leaves us with 554.
Append the next digit (9) from the dividend to 554 and continue with: 5549 / 839

Advancing to step 4:
839 can be fit into 5549 6 times, resulting in a remainder of 515.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 515 after subtracting 5034 from 5549.
Append the next digit (4) from the dividend to 515 and continue with: 5154 / 839

Moving on to step 5:
The number 839 fits into 5154 6 times, leaving a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 66.0
Subtracting 5034 from 5154 leaves us with 120.
Include the next digit (9) from the dividend after 120, then repeat: 1209 / 839

Step 6:
If we divide 1209 by 839, we get 1 and a remainder of 370.
The number 1 becomes the next digit in our result. 
Result so far: 661.0
Subtracting 839 from 1209 leaves us with 370.
Append the next digit (9) from the dividend to 370 and continue with: 3709 / 839

Moving on to step 7:
3709 divided by 839 is 4 with a remainder of 353.
Write down 4 as next digit of the result. 
Result so far: 6614.0
Subtract 3356 from 3709 to get 353.
Include the next digit (3) from the dividend after 353, then repeat: 3533 / 839

Moving on to step 8:
The number 839 fits into 3533 4 times, leaving a remainder of 177.
Record the quotient 4 as the next digit in the result. 
Result so far: 66144.0
Deduct 3356 from 3533 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.

On to step 9:
1770 divided by 839 is 2 with a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 66144.2
If we take 1678 away from 1770, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 10:
If we divide 920 by 839, we get 1 and a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 66144.21
If we take 839 away from 920, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 11:
839 can be fit into 810 0 times, resulting in a remainder of 810.
Put 0 as the next digit of the answer. 
Result so far: 66144.21
The remainder is 810 after subtracting 0 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Moving on to step 12:
If we divide 8100 by 839, we get 9 and a remainder of 549.
Put 9 as the next digit of the answer. 
Result so far: 66144.2109
Subtracting 7551 from 8100 leaves us with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

On to step 13:
If we divide 5490 by 839, we get 6 and a remainder of 456.
Use 6 as the next digit of our solution. 
Result so far: 66144.21096
Subtract 5034 from 5490 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 14:
When dividing 4560 by 839, we get 5 with a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 66144.210965
Subtract 4195 from 4560 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 15:
When dividing 3650 by 839, we get 4 with a remainder of 294.
Record the quotient 4 as the next digit in the result. 
Result so far: 66144.2109654
Subtracting 3356 from 3650 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 16:
If we divide 2940 by 839, we get 3 and a remainder of 423.
Put 3 as the next digit of the answer. 
Result so far: 66144.21096543
Subtracting 2517 from 2940 leaves us with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

The quotient of the division is 66144.21096543, and the remainder is 4.23e-07.
