We divide 71788120 by 678
The aim is to understand the frequency of 678 in 71788120.

Let's proceed to step 1:
678 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 678

Going ahead to step 2:
When dividing 71 by 678, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Grab the next digit (7) from the dividend, add it to 71, then carry on: 717 / 678

On to step 3:
The number 678 fits into 717 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 39 after subtracting 678 from 717.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 678

Step 4:
398 divided by 678 is 0 with a remainder of 398.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 398 leaves us with 398.
Include the next digit (8) from the dividend after 398, then repeat: 3988 / 678

Step 5:
678 can be fit into 3988 5 times, resulting in a remainder of 598.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
If we subtract 3390 from 3988, we get 598.
Take the next digit (1) from the dividend and append it to 598, then repeat: 5981 / 678

Moving on to step 6:
5981 divided by 678 is 8 with a remainder of 557.
Put 8 as the next digit of the answer. 
Result so far: 1058.0
If we take 5424 away from 5981, we end up with 557.
Take the next digit (2) from the dividend and append it to 557, then repeat: 5572 / 678

Advancing to step 7:
When dividing 5572 by 678, we get 8 with a remainder of 148.
The next digit of our result is 8. 
Result so far: 10588.0
If we take 5424 away from 5572, we end up with 148.
Fetch the next digit (0) from the dividend, attach it to 148 and continue: 1480 / 678

Moving on to step 8:
If we divide 1480 by 678, we get 2 and a remainder of 124.
The number 2 becomes the next digit in our result. 
Result so far: 105882.0
Subtract 1356 from 1480 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 9:
678 goes into 1240 1 times with a remainder of 562.
Put 1 as the next digit of the answer. 
Result so far: 105882.1
Deduct 678 from 1240 and we're left with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

On to step 10:
If we divide 5620 by 678, we get 8 and a remainder of 196.
The number 8 becomes the next digit in our result. 
Result so far: 105882.18
If we subtract 5424 from 5620, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 11:
678 can be fit into 1960 2 times, resulting in a remainder of 604.
The number 2 becomes the next digit in our result. 
Result so far: 105882.182
The remainder is 604 after subtracting 1356 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Step 12:
When dividing 6040 by 678, we get 8 with a remainder of 616.
Use 8 as the next digit of our solution. 
Result so far: 105882.1828
Subtract 5424 from 6040 to get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 13:
678 goes into 6160 9 times with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 105882.18289
If we subtract 6102 from 6160, we 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.

Let's proceed to step 14:
When dividing 580 by 678, we get 0 with a remainder of 580.
Write down 0 as next digit of the result. 
Result so far: 105882.18289
Deduct 0 from 580 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 15:
5800 divided by 678 is 8 with a remainder of 376.
The number 8 becomes the next digit in our result. 
Result so far: 105882.1828908
The remainder is 376 after subtracting 5424 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 16:
The number 678 fits into 3760 5 times, leaving a remainder of 370.
Put 5 as the next digit of the answer. 
Result so far: 105882.18289085
Subtract 3390 from 3760 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final outcome is 105882.18289085, with a leftover of 3.7e-07.
