We divide 78047497 by 397
The aim is to understand the frequency of 397 in 78047497.

On to step 1:
The number 397 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 397

On to step 2:
78 divided by 397 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (0) from the dividend after 78, then repeat: 780 / 397

Advancing to step 3:
The number 397 fits into 780 1 times, leaving a remainder of 383.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 397 from 780 and we're left with 383.
Grab the next digit (4) from the dividend, add it to 383, then carry on: 3834 / 397

Moving on to step 4:
397 can be fit into 3834 9 times, resulting in a remainder of 261.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 3573 away from 3834, we end up with 261.
Take the next digit (7) from the dividend and append it to 261, then repeat: 2617 / 397

Let's proceed to step 5:
397 can be fit into 2617 6 times, resulting in a remainder of 235.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
Deduct 2382 from 2617 and we're left with 235.
Append the next digit (4) from the dividend to 235 and continue with: 2354 / 397

Let's proceed to step 6:
When dividing 2354 by 397, we get 5 with a remainder of 369.
Use 5 as the next digit of our solution. 
Result so far: 1965.0
Deduct 1985 from 2354 and we're left with 369.
Include the next digit (9) from the dividend after 369, then repeat: 3699 / 397

On to step 7:
The number 397 fits into 3699 9 times, leaving a remainder of 126.
Write down 9 as next digit of the result. 
Result so far: 19659.0
Subtract 3573 from 3699 to get 126.
Include the next digit (7) from the dividend after 126, then repeat: 1267 / 397

Moving on to step 8:
1267 divided by 397 is 3 with a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 196593.0
If we take 1191 away from 1267, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 9:
760 divided by 397 is 1 with a remainder of 363.
The next digit of our result is 1. 
Result so far: 196593.1
If we take 397 away from 760, we end up with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Moving on to step 10:
397 can be fit into 3630 9 times, resulting in a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 196593.19
The remainder is 57 after subtracting 3573 from 3630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 11:
397 goes into 570 1 times with a remainder of 173.
Write down 1 as next digit of the result. 
Result so far: 196593.191
If we take 397 away from 570, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 12:
397 can be fit into 1730 4 times, resulting in a remainder of 142.
Use 4 as the next digit of our solution. 
Result so far: 196593.1914
The remainder is 142 after subtracting 1588 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 13:
The number 397 fits into 1420 3 times, leaving a remainder of 229.
The next digit of our result is 3. 
Result so far: 196593.19143
The remainder is 229 after subtracting 1191 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 14:
2290 divided by 397 is 5 with a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 196593.191435
The remainder is 305 after subtracting 1985 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 15:
397 can be fit into 3050 7 times, resulting in a remainder of 271.
Put 7 as the next digit of the answer. 
Result so far: 196593.1914357
If we take 2779 away from 3050, we end up with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 16:
If we divide 2710 by 397, we get 6 and a remainder of 328.
Record the quotient 6 as the next digit in the result. 
Result so far: 196593.19143576
Subtracting 2382 from 2710 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

In conclusion, the division gives 196593.19143576 with a balance of 3.28e-07.
