We're dividing 67392173 by 789 
The aim is to understand the frequency of 789 in 67392173.

Advancing to step 1:
6 divided by 789 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 789

Step 2:
The number 789 fits into 67 0 times, leaving a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Fetch the next digit (3) from the dividend, attach it to 67 and continue: 673 / 789

Let's proceed to step 3:
The number 789 fits into 673 0 times, leaving a remainder of 673.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 673, we end up with 673.
Fetch the next digit (9) from the dividend, attach it to 673 and continue: 6739 / 789

Moving on to step 4:
6739 divided by 789 is 8 with a remainder of 427.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 6312 from 6739, we get 427.
Grab the next digit (2) from the dividend, add it to 427, then carry on: 4272 / 789

Let's proceed to step 5:
The number 789 fits into 4272 5 times, leaving a remainder of 327.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
If we subtract 3945 from 4272, we get 327.
Include the next digit (1) from the dividend after 327, then repeat: 3271 / 789

On to step 6:
3271 divided by 789 is 4 with a remainder of 115.
The number 4 becomes the next digit in our result. 
Result so far: 854.0
Subtract 3156 from 3271 to get 115.
Include the next digit (7) from the dividend after 115, then repeat: 1157 / 789

On to step 7:
1157 divided by 789 is 1 with a remainder of 368.
Put 1 as the next digit of the answer. 
Result so far: 8541.0
Subtract 789 from 1157 to get 368.
Grab the next digit (3) from the dividend, add it to 368, then carry on: 3683 / 789

Moving on to step 8:
If we divide 3683 by 789, we get 4 and a remainder of 527.
Put 4 as the next digit of the answer. 
Result so far: 85414.0
Subtract 3156 from 3683 to get 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Moving on to step 9:
789 can be fit into 5270 6 times, resulting in a remainder of 536.
Use 6 as the next digit of our solution. 
Result so far: 85414.6
If we subtract 4734 from 5270, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 10:
If we divide 5360 by 789, we get 6 and a remainder of 626.
Put 6 as the next digit of the answer. 
Result so far: 85414.66
Subtracting 4734 from 5360 leaves us with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Our division results in 85414.66 with a remaining 0.626.
