We're dividing 44457122 by 789 
The aim is to understand the frequency of 789 in 44457122.

Going ahead to step 1:
789 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 789

Step 2:
789 goes into 44 0 times with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 789

Advancing to step 3:
444 divided by 789 is 0 with a remainder of 444.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 444 and we're left with 444.
Fetch the next digit (5) from the dividend, attach it to 444 and continue: 4445 / 789

Going ahead to step 4:
789 goes into 4445 5 times with a remainder of 500.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 3945 from 4445 and we're left with 500.
Append the next digit (7) from the dividend to 500 and continue with: 5007 / 789

Let's proceed to step 5:
5007 divided by 789 is 6 with a remainder of 273.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Deduct 4734 from 5007 and we're left with 273.
Append the next digit (1) from the dividend to 273 and continue with: 2731 / 789

Step 6:
When dividing 2731 by 789, we get 3 with a remainder of 364.
Use 3 as the next digit of our solution. 
Result so far: 563.0
Subtract 2367 from 2731 to get 364.
Fetch the next digit (2) from the dividend, attach it to 364 and continue: 3642 / 789

On to step 7:
3642 divided by 789 is 4 with a remainder of 486.
The number 4 becomes the next digit in our result. 
Result so far: 5634.0
If we take 3156 away from 3642, we end up with 486.
Include the next digit (2) from the dividend after 486, then repeat: 4862 / 789

On to step 8:
789 can be fit into 4862 6 times, resulting in a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 56346.0
Subtracting 4734 from 4862 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 9:
789 goes into 1280 1 times with a remainder of 491.
Record the quotient 1 as the next digit in the result. 
Result so far: 56346.1
If we subtract 789 from 1280, we get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

On to step 10:
When dividing 4910 by 789, we get 6 with a remainder of 176.
The next digit of our result is 6. 
Result so far: 56346.16
Deduct 4734 from 4910 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 11:
The number 789 fits into 1760 2 times, leaving a remainder of 182.
The next digit of our result is 2. 
Result so far: 56346.162
If we subtract 1578 from 1760, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 12:
The number 789 fits into 1820 2 times, leaving a remainder of 242.
Put 2 as the next digit of the answer. 
Result so far: 56346.1622
Deduct 1578 from 1820 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final outcome is 56346.1622, with a leftover of 0.00242.
