37542372 ÷ 789 
The aim is to understand the frequency of 789 in 37542372.

Let's proceed to step 1:
The number 789 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 789

Advancing to step 2:
If we divide 37 by 789, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 789

Going ahead to step 3:
When dividing 375 by 789, we get 0 with a remainder of 375.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 375, we end up with 375.
Fetch the next digit (4) from the dividend, attach it to 375 and continue: 3754 / 789

Advancing to step 4:
789 goes into 3754 4 times with a remainder of 598.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 3156 from 3754 and we're left with 598.
Fetch the next digit (2) from the dividend, attach it to 598 and continue: 5982 / 789

Let's proceed to step 5:
789 goes into 5982 7 times with a remainder of 459.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtract 5523 from 5982 to get 459.
Fetch the next digit (3) from the dividend, attach it to 459 and continue: 4593 / 789

Step 6:
The number 789 fits into 4593 5 times, leaving a remainder of 648.
Put 5 as the next digit of the answer. 
Result so far: 475.0
Subtract 3945 from 4593 to get 648.
Grab the next digit (7) from the dividend, add it to 648, then carry on: 6487 / 789

Step 7:
6487 divided by 789 is 8 with a remainder of 175.
The next digit of our result is 8. 
Result so far: 4758.0
If we subtract 6312 from 6487, we get 175.
Grab the next digit (2) from the dividend, add it to 175, then carry on: 1752 / 789

Going ahead to step 8:
If we divide 1752 by 789, we get 2 and a remainder of 174.
Record the quotient 2 as the next digit in the result. 
Result so far: 47582.0
If we take 1578 away from 1752, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 9:
If we divide 1740 by 789, we get 2 and a remainder of 162.
The next digit of our result is 2. 
Result so far: 47582.2
Deduct 1578 from 1740 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 10:
789 can be fit into 1620 2 times, resulting in a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 47582.22
If we subtract 1578 from 1620, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 47582.22 and a remainder of 0.042.
