We divide 154437 by 78
The aim is to understand the frequency of 78 in 154437.

Going ahead to step 1:
78 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 78

Step 2:
When dividing 15 by 78, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 78

Moving on to step 3:
78 can be fit into 154 1 times, resulting in a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 78 from 154 to get 76.
Fetch the next digit (4) from the dividend, attach it to 76 and continue: 764 / 78

Going ahead to step 4:
The number 78 fits into 764 9 times, leaving a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 702 from 764 to get 62.
Fetch the next digit (3) from the dividend, attach it to 62 and continue: 623 / 78

On to step 5:
When dividing 623 by 78, we get 7 with a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
Deduct 546 from 623 and we're left with 77.
Take the next digit (7) from the dividend and append it to 77, then repeat: 777 / 78

Step 6:
The number 78 fits into 777 9 times, leaving a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 1979.0
Subtract 702 from 777 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 7:
78 can be fit into 750 9 times, resulting in a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 1979.9
If we subtract 702 from 750, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
480 divided by 78 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 1979.96
If we take 468 away from 480, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 1979.961
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
When dividing 420 by 78, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1979.9615
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
78 can be fit into 300 3 times, resulting in a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 1979.96153
If we subtract 234 from 300, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
If we divide 660 by 78, we get 8 and a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 1979.961538
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 1979.9615384
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
78 goes into 480 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 1979.96153846
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 1979.96153846, with a leftover of 1.2e-08.
