We look at the division of 85077765 by 378 
The aim is to understand the frequency of 378 in 85077765.

Advancing to step 1:
378 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 378

Moving on to step 2:
378 can be fit into 85 0 times, resulting in a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Append the next digit (0) from the dividend to 85 and continue with: 850 / 378

Step 3:
If we divide 850 by 378, we get 2 and a remainder of 94.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 756 from 850 and we're left with 94.
Bring next digit (7) of the dividend behind the 94 and repeat the process: 947 / 378

Moving on to step 4:
947 divided by 378 is 2 with a remainder of 191.
The next digit of our result is 2. 
Result so far: 22.0
The remainder is 191 after subtracting 756 from 947.
Fetch the next digit (7) from the dividend, attach it to 191 and continue: 1917 / 378

Step 5:
378 goes into 1917 5 times with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 225.0
Subtract 1890 from 1917 to get 27.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 378

Moving on to step 6:
When dividing 277 by 378, we get 0 with a remainder of 277.
Put 0 as the next digit of the answer. 
Result so far: 2250.0
If we take 0 away from 277, we end up with 277.
Include the next digit (6) from the dividend after 277, then repeat: 2776 / 378

On to step 7:
2776 divided by 378 is 7 with a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 22507.0
If we take 2646 away from 2776, we end up with 130.
Append the next digit (5) from the dividend to 130 and continue with: 1305 / 378

Moving on to step 8:
378 goes into 1305 3 times with a remainder of 171.
Record the quotient 3 as the next digit in the result. 
Result so far: 225073.0
Subtract 1134 from 1305 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 9:
If we divide 1710 by 378, we get 4 and a remainder of 198.
Use 4 as the next digit of our solution. 
Result so far: 225073.4
The remainder is 198 after subtracting 1512 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 10:
378 goes into 1980 5 times with a remainder of 90.
The next digit of our result is 5. 
Result so far: 225073.45
Subtract 1890 from 1980 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
If we divide 900 by 378, we get 2 and a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 225073.452
Subtract 756 from 900 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 12:
378 goes into 1440 3 times with a remainder of 306.
The next digit of our result is 3. 
Result so far: 225073.4523
Deduct 1134 from 1440 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 13:
The number 378 fits into 3060 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 225073.45238
The remainder is 36 after subtracting 3024 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
378 can be fit into 360 0 times, resulting in a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 225073.45238
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 15:
The number 378 fits into 3600 9 times, leaving a remainder of 198.
Put 9 as the next digit of the answer. 
Result so far: 225073.4523809
Subtract 3402 from 3600 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 16:
1980 divided by 378 is 5 with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 225073.45238095
If we subtract 1890 from 1980, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 225073.45238095 with a remaining 9e-08.
