We look at the division of 132874 by 78 
The aim is to understand the frequency of 78 in 132874.

Let's proceed to step 1:
When dividing 1 by 78, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 78

On to step 2:
78 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 78

Moving on to step 3:
78 can be fit into 132 1 times, resulting in a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 78 from 132, we get 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 78

On to step 4:
548 divided by 78 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 546 from 548 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 78

Moving on to step 5:
78 goes into 27 0 times with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
Subtracting 0 from 27 leaves us with 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 78

Advancing to step 6:
78 goes into 274 3 times with a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 1703.0
If we take 234 away from 274, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
When dividing 400 by 78, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 1703.5
Subtract 390 from 400 to 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.

Let's proceed to step 8:
If we divide 100 by 78, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1703.51
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.

On to step 9:
78 goes into 220 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 1703.512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
78 can be fit into 640 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1703.5128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
The number 78 fits into 160 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1703.51282
If we take 156 away from 160, we end up 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.

Step 12:
78 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1703.51282
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
78 goes into 400 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 1703.5128205
Deduct 390 from 400 and we're left 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 14:
If we divide 100 by 78, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1703.51282051
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.

The final outcome is 1703.51282051, with a leftover of 2.2e-08.
