Let's divide 1972745 by 789
The aim is to understand the frequency of 789 in 1972745.

Let's proceed to step 1:
If we divide 1 by 789, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 789

Moving on to step 2:
789 goes into 19 0 times with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 789

Going ahead to step 3:
789 can be fit into 197 0 times, resulting in a remainder of 197.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 197 after subtracting 0 from 197.
Include the next digit (2) from the dividend after 197, then repeat: 1972 / 789

Moving on to step 4:
When dividing 1972 by 789, we get 2 with a remainder of 394.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1578 away from 1972, we end up with 394.
Grab the next digit (7) from the dividend, add it to 394, then carry on: 3947 / 789

Moving on to step 5:
When dividing 3947 by 789, we get 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 3945 away from 3947, we end up with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 789

Moving on to step 6:
789 can be fit into 24 0 times, resulting in a remainder of 24.
The next digit of our result is 0. 
Result so far: 250.0
If we take 0 away from 24, we end up with 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 789

Let's proceed to step 7:
The number 789 fits into 245 0 times, leaving a remainder of 245.
The number 0 becomes the next digit in our result. 
Result so far: 2500.0
If we subtract 0 from 245, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 8:
The number 789 fits into 2450 3 times, leaving a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 2500.3
Deduct 2367 from 2450 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 9:
The number 789 fits into 830 1 times, leaving a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 2500.31
Subtract 789 from 830 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 10:
The number 789 fits into 410 0 times, leaving a remainder of 410.
The next digit of our result is 0. 
Result so far: 2500.31
Subtracting 0 from 410 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 11:
789 goes into 4100 5 times with a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 2500.3105
Subtract 3945 from 4100 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 12:
789 goes into 1550 1 times with a remainder of 761.
The next digit of our result is 1. 
Result so far: 2500.31051
If we take 789 away from 1550, we end up with 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Step 13:
If we divide 7610 by 789, we get 9 and a remainder of 509.
The next digit of our result is 9. 
Result so far: 2500.310519
Subtract 7101 from 7610 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Advancing to step 14:
789 goes into 5090 6 times with a remainder of 356.
Put 6 as the next digit of the answer. 
Result so far: 2500.3105196
Subtract 4734 from 5090 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 15:
789 can be fit into 3560 4 times, resulting in a remainder of 404.
Write down 4 as next digit of the result. 
Result so far: 2500.31051964
If we subtract 3156 from 3560, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

In conclusion, the division gives 2500.31051964 with a balance of 4.04e-07.
