We divide 7976397 by 378
The aim is to understand the frequency of 378 in 7976397.

On to step 1:
378 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 378

On to step 2:
378 goes into 79 0 times with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Include the next digit (7) from the dividend after 79, then repeat: 797 / 378

Going ahead to step 3:
The number 378 fits into 797 2 times, leaving a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 756 from 797 and we're left with 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 378

Advancing to step 4:
416 divided by 378 is 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 378 from 416 and we're left with 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 378

Step 5:
When dividing 383 by 378, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 211.0
The remainder is 5 after subtracting 378 from 383.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 378

Let's proceed to step 6:
If we divide 59 by 378, we get 0 and a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 2110.0
Subtracting 0 from 59 leaves us with 59.
Fetch the next digit (7) from the dividend, attach it to 59 and continue: 597 / 378

On to step 7:
When dividing 597 by 378, we get 1 with a remainder of 219.
The number 1 becomes the next digit in our result. 
Result so far: 21101.0
If we subtract 378 from 597, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Step 8:
The number 378 fits into 2190 5 times, leaving a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 21101.5
Deduct 1890 from 2190 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 9:
378 can be fit into 3000 7 times, resulting in a remainder of 354.
The number 7 becomes the next digit in our result. 
Result so far: 21101.57
Subtracting 2646 from 3000 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 10:
If we divide 3540 by 378, we get 9 and a remainder of 138.
The next digit of our result is 9. 
Result so far: 21101.579
The remainder is 138 after subtracting 3402 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 11:
If we divide 1380 by 378, we get 3 and a remainder of 246.
Put 3 as the next digit of the answer. 
Result so far: 21101.5793
If we take 1134 away from 1380, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 12:
If we divide 2460 by 378, we get 6 and a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 21101.57936
Deduct 2268 from 2460 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 13:
378 can be fit into 1920 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 21101.579365
The remainder is 30 after subtracting 1890 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
The number 378 fits into 300 0 times, leaving a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 21101.579365
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 15:
3000 divided by 378 is 7 with a remainder of 354.
Use 7 as the next digit of our solution. 
Result so far: 21101.57936507
If we subtract 2646 from 3000, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

In conclusion, the division gives 21101.57936507 with a balance of 3.54e-07.
