71754764 ÷ 378 
The aim is to understand the frequency of 378 in 71754764.

Going ahead to step 1:
378 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 378

Going ahead to step 2:
When dividing 71 by 378, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 378

Advancing to step 3:
The number 378 fits into 717 1 times, leaving a remainder of 339.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 378 from 717 leaves us with 339.
Bring next digit (5) of the dividend behind the 339 and repeat the process: 3395 / 378

On to step 4:
If we divide 3395 by 378, we get 8 and a remainder of 371.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtracting 3024 from 3395 leaves us with 371.
Take the next digit (4) from the dividend and append it to 371, then repeat: 3714 / 378

Let's proceed to step 5:
If we divide 3714 by 378, we get 9 and a remainder of 312.
Use 9 as the next digit of our solution. 
Result so far: 189.0
Subtracting 3402 from 3714 leaves us with 312.
Fetch the next digit (7) from the dividend, attach it to 312 and continue: 3127 / 378

Moving on to step 6:
378 can be fit into 3127 8 times, resulting in a remainder of 103.
Use 8 as the next digit of our solution. 
Result so far: 1898.0
The remainder is 103 after subtracting 3024 from 3127.
Grab the next digit (6) from the dividend, add it to 103, then carry on: 1036 / 378

Advancing to step 7:
When dividing 1036 by 378, we get 2 with a remainder of 280.
Write down 2 as next digit of the result. 
Result so far: 18982.0
If we subtract 756 from 1036, we get 280.
Include the next digit (4) from the dividend after 280, then repeat: 2804 / 378

Let's proceed to step 8:
The number 378 fits into 2804 7 times, leaving a remainder of 158.
The next digit of our result is 7. 
Result so far: 189827.0
Subtract 2646 from 2804 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 9:
The number 378 fits into 1580 4 times, leaving a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 189827.4
If we subtract 1512 from 1580, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
378 goes into 680 1 times with a remainder of 302.
Record the quotient 1 as the next digit in the result. 
Result so far: 189827.41
The remainder is 302 after subtracting 378 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 11:
378 goes into 3020 7 times with a remainder of 374.
Use 7 as the next digit of our solution. 
Result so far: 189827.417
The remainder is 374 after subtracting 2646 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 12:
3740 divided by 378 is 9 with a remainder of 338.
The number 9 becomes the next digit in our result. 
Result so far: 189827.4179
Subtracting 3402 from 3740 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 13:
If we divide 3380 by 378, we get 8 and a remainder of 356.
Put 8 as the next digit of the answer. 
Result so far: 189827.41798
The remainder is 356 after subtracting 3024 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 14:
378 can be fit into 3560 9 times, resulting in a remainder of 158.
The number 9 becomes the next digit in our result. 
Result so far: 189827.417989
If we take 3402 away from 3560, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 15:
1580 divided by 378 is 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 189827.4179894
If we subtract 1512 from 1580, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 16:
378 can be fit into 680 1 times, resulting in a remainder of 302.
The number 1 becomes the next digit in our result. 
Result so far: 189827.41798941
The remainder is 302 after subtracting 378 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

The final outcome is 189827.41798941, with a leftover of 3.02e-07.
