Let's divide 53564194 by 678
The aim is to understand the frequency of 678 in 53564194.

Step 1:
5 divided by 678 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 678

On to step 2:
If we divide 53 by 678, we get 0 and a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 678

Step 3:
678 goes into 535 0 times with a remainder of 535.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 535 leaves us with 535.
Grab the next digit (6) from the dividend, add it to 535, then carry on: 5356 / 678

Going ahead to step 4:
678 goes into 5356 7 times with a remainder of 610.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 4746 from 5356 leaves us with 610.
Grab the next digit (4) from the dividend, add it to 610, then carry on: 6104 / 678

On to step 5:
When dividing 6104 by 678, we get 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 79.0
Subtract 6102 from 6104 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 678

Moving on to step 6:
If we divide 21 by 678, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 790.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 678

Step 7:
When dividing 219 by 678, we get 0 with a remainder of 219.
Write down 0 as next digit of the result. 
Result so far: 7900.0
Deduct 0 from 219 and we're left with 219.
Include the next digit (4) from the dividend after 219, then repeat: 2194 / 678

Going ahead to step 8:
The number 678 fits into 2194 3 times, leaving a remainder of 160.
Use 3 as the next digit of our solution. 
Result so far: 79003.0
The remainder is 160 after subtracting 2034 from 2194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 9:
The number 678 fits into 1600 2 times, leaving a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 79003.2
Deduct 1356 from 1600 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 10:
2440 divided by 678 is 3 with a remainder of 406.
Use 3 as the next digit of our solution. 
Result so far: 79003.23
The remainder is 406 after subtracting 2034 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 11:
When dividing 4060 by 678, we get 5 with a remainder of 670.
Put 5 as the next digit of the answer. 
Result so far: 79003.235
The remainder is 670 after subtracting 3390 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 12:
678 goes into 6700 9 times with a remainder of 598.
Put 9 as the next digit of the answer. 
Result so far: 79003.2359
Deduct 6102 from 6700 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 13:
5980 divided by 678 is 8 with a remainder of 556.
Record the quotient 8 as the next digit in the result. 
Result so far: 79003.23598
If we take 5424 away from 5980, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 14:
The number 678 fits into 5560 8 times, leaving a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 79003.235988
The remainder is 136 after subtracting 5424 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 79003.235988 and a remainder of 1.36e-05.
