451543 ÷ 78 
The aim is to understand the frequency of 78 in 451543.

Let's proceed to step 1:
78 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 78

On to step 2:
78 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 78

Advancing to step 3:
78 can be fit into 451 5 times, resulting in a remainder of 61.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 61 after subtracting 390 from 451.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 78

Advancing to step 4:
When dividing 615 by 78, we get 7 with a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Subtracting 546 from 615 leaves us with 69.
Grab the next digit (4) from the dividend, add it to 69, then carry on: 694 / 78

Advancing to step 5:
694 divided by 78 is 8 with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 578.0
Subtract 624 from 694 to get 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 78

Going ahead to step 6:
78 can be fit into 703 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 5789.0
Deduct 702 from 703 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
78 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 5789.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
78 can be fit into 100 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 5789.01
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 5789.012
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
If we divide 640 by 78, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 5789.0128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
160 divided by 78 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 5789.01282
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
If we divide 40 by 78, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5789.01282
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
When dividing 400 by 78, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5789.0128205
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
When dividing 100 by 78, we get 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 5789.01282051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 5789.01282051 with a balance of 2.2e-08.
