We're dividing 292810 by 78 
The aim is to understand the frequency of 78 in 292810.

Advancing to step 1:
2 divided by 78 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 78

Going ahead to step 2:
The number 78 fits into 29 0 times, leaving a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 78

Step 3:
78 goes into 292 3 times with a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 234 from 292 and we're left with 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 78

Going ahead to step 4:
When dividing 588 by 78, we get 7 with a remainder of 42.
The next digit of our result is 7. 
Result so far: 37.0
If we take 546 away from 588, we end up with 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 78

Step 5:
If we divide 421 by 78, we get 5 and a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 375.0
Subtract 390 from 421 to get 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 78

Advancing to step 6:
78 can be fit into 310 3 times, resulting in a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 3753.0
If we subtract 234 from 310, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 7:
78 goes into 760 9 times with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 3753.9
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 8:
78 goes into 580 7 times with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 3753.97
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
If we divide 340 by 78, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 3753.974
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
If we divide 280 by 78, we get 3 and a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 3753.9743
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 3753.97435
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
The number 78 fits into 700 8 times, leaving a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 3753.974358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
78 goes into 760 9 times with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 3753.9743589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 14:
580 divided by 78 is 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 3753.97435897
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 3753.97435897 and a remainder of 3.4e-08.
