77155811 ÷ 378 
The aim is to understand the frequency of 378 in 77155811.

Going ahead to step 1:
When dividing 7 by 378, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 378

On to step 2:
378 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 378

Moving on to step 3:
378 can be fit into 771 2 times, resulting in a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 15 after subtracting 756 from 771.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 378

Going ahead to step 4:
378 goes into 155 0 times with a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 155 to get 155.
Fetch the next digit (5) from the dividend, attach it to 155 and continue: 1555 / 378

On to step 5:
If we divide 1555 by 378, we get 4 and a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
If we subtract 1512 from 1555, we get 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 378

Step 6:
378 goes into 438 1 times with a remainder of 60.
The next digit of our result is 1. 
Result so far: 2041.0
Deduct 378 from 438 and we're left with 60.
Take the next digit (1) from the dividend and append it to 60, then repeat: 601 / 378

Advancing to step 7:
The number 378 fits into 601 1 times, leaving a remainder of 223.
Record the quotient 1 as the next digit in the result. 
Result so far: 20411.0
Subtracting 378 from 601 leaves us with 223.
Fetch the next digit (1) from the dividend, attach it to 223 and continue: 2231 / 378

Step 8:
The number 378 fits into 2231 5 times, leaving a remainder of 341.
Record the quotient 5 as the next digit in the result. 
Result so far: 204115.0
Subtract 1890 from 2231 to get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 9:
378 goes into 3410 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 204115.9
Subtracting 3402 from 3410 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 378 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 204115.9
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
The number 378 fits into 800 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 204115.902
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
378 can be fit into 440 1 times, resulting in a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 204115.9021
If we subtract 378 from 440, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 13:
When dividing 620 by 378, we get 1 with a remainder of 242.
Put 1 as the next digit of the answer. 
Result so far: 204115.90211
The remainder is 242 after subtracting 378 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

In conclusion, the division gives 204115.90211 with a balance of 0.000242.
