39154342 divided by 397 
The aim is to understand the frequency of 397 in 39154342.

Let's proceed to step 1:
If we divide 3 by 397, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 397

Let's proceed to step 2:
If we divide 39 by 397, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 397

Step 3:
If we divide 391 by 397, we get 0 and a remainder of 391.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 391 to get 391.
Fetch the next digit (5) from the dividend, attach it to 391 and continue: 3915 / 397

Step 4:
If we divide 3915 by 397, we get 9 and a remainder of 342.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 342 after subtracting 3573 from 3915.
Append the next digit (4) from the dividend to 342 and continue with: 3424 / 397

Going ahead to step 5:
When dividing 3424 by 397, we get 8 with a remainder of 248.
Write down 8 as next digit of the result. 
Result so far: 98.0
Deduct 3176 from 3424 and we're left with 248.
Include the next digit (3) from the dividend after 248, then repeat: 2483 / 397

Let's proceed to step 6:
If we divide 2483 by 397, we get 6 and a remainder of 101.
The number 6 becomes the next digit in our result. 
Result so far: 986.0
Subtracting 2382 from 2483 leaves us with 101.
Fetch the next digit (4) from the dividend, attach it to 101 and continue: 1014 / 397

Advancing to step 7:
If we divide 1014 by 397, we get 2 and a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 9862.0
Subtract 794 from 1014 to get 220.
Bring next digit (2) of the dividend behind the 220 and repeat the process: 2202 / 397

On to step 8:
2202 divided by 397 is 5 with a remainder of 217.
Use 5 as the next digit of our solution. 
Result so far: 98625.0
If we take 1985 away from 2202, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 9:
When dividing 2170 by 397, we get 5 with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 98625.5
The remainder is 185 after subtracting 1985 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 10:
397 can be fit into 1850 4 times, resulting in a remainder of 262.
Record the quotient 4 as the next digit in the result. 
Result so far: 98625.54
Subtract 1588 from 1850 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 11:
2620 divided by 397 is 6 with a remainder of 238.
The number 6 becomes the next digit in our result. 
Result so far: 98625.546
The remainder is 238 after subtracting 2382 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 12:
If we divide 2380 by 397, we get 5 and a remainder of 395.
Use 5 as the next digit of our solution. 
Result so far: 98625.5465
Subtract 1985 from 2380 to get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 13:
397 goes into 3950 9 times with a remainder of 377.
Put 9 as the next digit of the answer. 
Result so far: 98625.54659
The remainder is 377 after subtracting 3573 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Let's proceed to step 14:
If we divide 3770 by 397, we get 9 and a remainder of 197.
Use 9 as the next digit of our solution. 
Result so far: 98625.546599
Deduct 3573 from 3770 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

The quotient of the division is 98625.546599, and the remainder is 1.97e-05.
