We divide 7877195 by 378
The aim is to understand the frequency of 378 in 7877195.

Going ahead to step 1:
378 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 378

Step 2:
The number 378 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 378

On to step 3:
787 divided by 378 is 2 with a remainder of 31.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 756 from 787 to get 31.
Include the next digit (7) from the dividend after 31, then repeat: 317 / 378

Let's proceed to step 4:
378 goes into 317 0 times with a remainder of 317.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 317 leaves us with 317.
Include the next digit (1) from the dividend after 317, then repeat: 3171 / 378

Going ahead to step 5:
3171 divided by 378 is 8 with a remainder of 147.
Use 8 as the next digit of our solution. 
Result so far: 208.0
Subtracting 3024 from 3171 leaves us with 147.
Append the next digit (9) from the dividend to 147 and continue with: 1479 / 378

Going ahead to step 6:
If we divide 1479 by 378, we get 3 and a remainder of 345.
The number 3 becomes the next digit in our result. 
Result so far: 2083.0
Subtracting 1134 from 1479 leaves us with 345.
Grab the next digit (5) from the dividend, add it to 345, then carry on: 3455 / 378

Going ahead to step 7:
When dividing 3455 by 378, we get 9 with a remainder of 53.
The next digit of our result is 9. 
Result so far: 20839.0
If we subtract 3402 from 3455, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 8:
If we divide 530 by 378, we get 1 and a remainder of 152.
Use 1 as the next digit of our solution. 
Result so far: 20839.1
Deduct 378 from 530 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 9:
378 goes into 1520 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 20839.14
Deduct 1512 from 1520 and we're left 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.

Step 10:
The number 378 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 20839.14
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
378 goes into 800 2 times with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 20839.1402
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
If we divide 440 by 378, we get 1 and a remainder of 62.
The next digit of our result is 1. 
Result so far: 20839.14021
Subtracting 378 from 440 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
When dividing 620 by 378, we get 1 with a remainder of 242.
Use 1 as the next digit of our solution. 
Result so far: 20839.140211
Subtracting 378 from 620 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final result is 20839.140211 with a remainder of 2.42e-05.
