We divide 379426 by 78
The aim is to understand the frequency of 78 in 379426.

Step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 78

Step 2:
78 can be fit into 37 0 times, resulting in a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 78

Step 3:
The number 78 fits into 379 4 times, leaving a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 312 from 379, we get 67.
Append the next digit (4) from the dividend to 67 and continue with: 674 / 78

Let's proceed to step 4:
78 goes into 674 8 times with a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we take 624 away from 674, we end up with 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 78

Going ahead to step 5:
If we divide 502 by 78, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 486.0
If we subtract 468 from 502, we get 34.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 78

Moving on to step 6:
When dividing 346 by 78, we get 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 4864.0
Subtracting 312 from 346 leaves us 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.

Moving on to step 7:
When dividing 340 by 78, we get 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 4864.4
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 4864.43
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
78 can be fit into 460 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 4864.435
Deduct 390 from 460 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
When dividing 700 by 78, we get 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 4864.4358
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
When dividing 760 by 78, we get 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 4864.43589
If we take 702 away from 760, we end up 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 12:
580 divided by 78 is 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 4864.435897
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.

Going ahead to step 13:
78 goes into 340 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 4864.4358974
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 4864.43589743
Subtracting 234 from 280 leaves us 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.

The final outcome is 4864.43589743, with a leftover of 4.6e-08.
