Let's divide 9591716 by 378
The aim is to understand the frequency of 378 in 9591716.

Let's proceed to step 1:
9 divided by 378 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 378

Going ahead to step 2:
378 goes into 95 0 times with a remainder of 95.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 95, we end up with 95.
Bring next digit (9) of the dividend behind the 95 and repeat the process: 959 / 378

Let's proceed to step 3:
The number 378 fits into 959 2 times, leaving a remainder of 203.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 756 from 959, we get 203.
Append the next digit (1) from the dividend to 203 and continue with: 2031 / 378

Let's proceed to step 4:
When dividing 2031 by 378, we get 5 with a remainder of 141.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 1890 away from 2031, we end up with 141.
Include the next digit (7) from the dividend after 141, then repeat: 1417 / 378

Let's proceed to step 5:
378 can be fit into 1417 3 times, resulting in a remainder of 283.
The next digit of our result is 3. 
Result so far: 253.0
If we take 1134 away from 1417, we end up with 283.
Grab the next digit (1) from the dividend, add it to 283, then carry on: 2831 / 378

Advancing to step 6:
378 goes into 2831 7 times with a remainder of 185.
Put 7 as the next digit of the answer. 
Result so far: 2537.0
Deduct 2646 from 2831 and we're left with 185.
Include the next digit (6) from the dividend after 185, then repeat: 1856 / 378

Advancing to step 7:
The number 378 fits into 1856 4 times, leaving a remainder of 344.
Record the quotient 4 as the next digit in the result. 
Result so far: 25374.0
The remainder is 344 after subtracting 1512 from 1856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 8:
The number 378 fits into 3440 9 times, leaving a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 25374.9
Subtracting 3402 from 3440 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
If we divide 380 by 378, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 25374.91
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
378 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 25374.91
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 378 is 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 25374.91
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 25374.91, with a leftover of 0.002.
