43817414 ÷ 678 
The aim is to understand the frequency of 678 in 43817414.

Moving on to step 1:
4 divided by 678 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 678

Moving on to step 2:
If we divide 43 by 678, we get 0 and a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 678

On to step 3:
678 can be fit into 438 0 times, resulting in a remainder of 438.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 438, we end up with 438.
Bring next digit (1) of the dividend behind the 438 and repeat the process: 4381 / 678

On to step 4:
The number 678 fits into 4381 6 times, leaving a remainder of 313.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 4068 from 4381 leaves us with 313.
Grab the next digit (7) from the dividend, add it to 313, then carry on: 3137 / 678

Let's proceed to step 5:
The number 678 fits into 3137 4 times, leaving a remainder of 425.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we subtract 2712 from 3137, we get 425.
Append the next digit (4) from the dividend to 425 and continue with: 4254 / 678

Let's proceed to step 6:
If we divide 4254 by 678, we get 6 and a remainder of 186.
Record the quotient 6 as the next digit in the result. 
Result so far: 646.0
Subtracting 4068 from 4254 leaves us with 186.
Include the next digit (1) from the dividend after 186, then repeat: 1861 / 678

Step 7:
The number 678 fits into 1861 2 times, leaving a remainder of 505.
Use 2 as the next digit of our solution. 
Result so far: 6462.0
The remainder is 505 after subtracting 1356 from 1861.
Take the next digit (4) from the dividend and append it to 505, then repeat: 5054 / 678

Moving on to step 8:
When dividing 5054 by 678, we get 7 with a remainder of 308.
The number 7 becomes the next digit in our result. 
Result so far: 64627.0
If we subtract 4746 from 5054, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 9:
If we divide 3080 by 678, we get 4 and a remainder of 368.
Record the quotient 4 as the next digit in the result. 
Result so far: 64627.4
Subtract 2712 from 3080 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 10:
If we divide 3680 by 678, we get 5 and a remainder of 290.
Use 5 as the next digit of our solution. 
Result so far: 64627.45
If we subtract 3390 from 3680, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 11:
When dividing 2900 by 678, we get 4 with a remainder of 188.
Put 4 as the next digit of the answer. 
Result so far: 64627.454
The remainder is 188 after subtracting 2712 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 12:
If we divide 1880 by 678, we get 2 and a remainder of 524.
Write down 2 as next digit of the result. 
Result so far: 64627.4542
If we subtract 1356 from 1880, we get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 13:
The number 678 fits into 5240 7 times, leaving a remainder of 494.
The next digit of our result is 7. 
Result so far: 64627.45427
Deduct 4746 from 5240 and we're left with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 14:
678 can be fit into 4940 7 times, resulting in a remainder of 194.
Record the quotient 7 as the next digit in the result. 
Result so far: 64627.454277
If we take 4746 away from 4940, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The final outcome is 64627.454277, with a leftover of 1.94e-05.
