We divide 122261 by 78
The aim is to understand the frequency of 78 in 122261.

Moving on to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 78

Advancing to step 2:
If we divide 12 by 78, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 78

Advancing to step 3:
78 goes into 122 1 times with a remainder of 44.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 44 after subtracting 78 from 122.
Take the next digit (2) from the dividend and append it to 44, then repeat: 442 / 78

Let's proceed to step 4:
78 can be fit into 442 5 times, resulting in a remainder of 52.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 390 away from 442, we end up with 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 78

Advancing to step 5:
78 can be fit into 526 6 times, resulting in a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 156.0
Subtracting 468 from 526 leaves us with 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 78

Moving on to step 6:
When dividing 581 by 78, we get 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 1567.0
Deduct 546 from 581 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
The number 78 fits into 350 4 times, leaving a remainder of 38.
The next digit of our result is 4. 
Result so far: 1567.4
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
380 divided by 78 is 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 1567.44
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 1567.44, and the remainder is 0.068.
