376810 ÷ 78 
The aim is to understand the frequency of 78 in 376810.

Advancing to step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 78

On to step 2:
The number 78 fits into 37 0 times, leaving a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 78

Moving on to step 3:
78 goes into 376 4 times with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 312 from 376 to get 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 78

Going ahead to step 4:
78 can be fit into 648 8 times, resulting in a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtract 624 from 648 to get 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 78

Let's proceed to step 5:
78 goes into 241 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 483.0
Subtract 234 from 241 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 78

Step 6:
If we divide 70 by 78, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 4830.0
Subtract 0 from 70 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 7:
When dividing 700 by 78, we get 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 4830.8
Deduct 624 from 700 and we're left 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.

On to step 8:
If we divide 760 by 78, we get 9 and a remainder of 58.
The next digit of our result is 9. 
Result so far: 4830.89
The remainder is 58 after subtracting 702 from 760.
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 9:
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: 4830.897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
If we divide 340 by 78, we get 4 and a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 4830.8974
Subtracting 312 from 340 leaves us 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.

Step 11:
When dividing 280 by 78, we get 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 4830.89743
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.

Moving on to step 12:
78 goes into 460 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 4830.897435
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.

Let's proceed to step 13:
If we divide 700 by 78, we get 8 and a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 4830.8974358
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 14:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 4830.89743589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 4830.89743589 and a remainder of 5.8e-08.
