We look at the division of 51812703 by 844 
The aim is to understand the frequency of 844 in 51812703.

On to step 1:
844 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 844

Step 2:
51 divided by 844 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 844

Let's proceed to step 3:
844 can be fit into 518 0 times, resulting in a remainder of 518.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 518, we get 518.
Append the next digit (1) from the dividend to 518 and continue with: 5181 / 844

On to step 4:
The number 844 fits into 5181 6 times, leaving a remainder of 117.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 117 after subtracting 5064 from 5181.
Take the next digit (2) from the dividend and append it to 117, then repeat: 1172 / 844

Going ahead to step 5:
844 can be fit into 1172 1 times, resulting in a remainder of 328.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 844 away from 1172, we end up with 328.
Append the next digit (7) from the dividend to 328 and continue with: 3287 / 844

Step 6:
When dividing 3287 by 844, we get 3 with a remainder of 755.
The number 3 becomes the next digit in our result. 
Result so far: 613.0
Subtract 2532 from 3287 to get 755.
Include the next digit (0) from the dividend after 755, then repeat: 7550 / 844

Going ahead to step 7:
844 goes into 7550 8 times with a remainder of 798.
Record the quotient 8 as the next digit in the result. 
Result so far: 6138.0
Deduct 6752 from 7550 and we're left with 798.
Fetch the next digit (3) from the dividend, attach it to 798 and continue: 7983 / 844

Step 8:
844 can be fit into 7983 9 times, resulting in a remainder of 387.
Write down 9 as next digit of the result. 
Result so far: 61389.0
Deduct 7596 from 7983 and we're left with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Going ahead to step 9:
844 can be fit into 3870 4 times, resulting in a remainder of 494.
Record the quotient 4 as the next digit in the result. 
Result so far: 61389.4
Subtracting 3376 from 3870 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Going ahead to step 10:
844 goes into 4940 5 times with a remainder of 720.
Write down 5 as next digit of the result. 
Result so far: 61389.45
Subtract 4220 from 4940 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 11:
844 can be fit into 7200 8 times, resulting in a remainder of 448.
The number 8 becomes the next digit in our result. 
Result so far: 61389.458
If we take 6752 away from 7200, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 12:
If we divide 4480 by 844, we get 5 and a remainder of 260.
Record the quotient 5 as the next digit in the result. 
Result so far: 61389.4585
Subtract 4220 from 4480 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 13:
2600 divided by 844 is 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 61389.45853
If we subtract 2532 from 2600, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
844 goes into 680 0 times with a remainder of 680.
The next digit of our result is 0. 
Result so far: 61389.45853
Deduct 0 from 680 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 15:
6800 divided by 844 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 61389.4585308
Subtract 6752 from 6800 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 16:
844 can be fit into 480 0 times, resulting in a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 61389.4585308
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final outcome is 61389.4585308, with a leftover of 4.8e-07.
