We're dividing 3326196 by 397 
The aim is to understand the frequency of 397 in 3326196.

Moving on to step 1:
If we divide 3 by 397, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 397

On to step 2:
397 can be fit into 33 0 times, resulting in a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Take the next digit (2) from the dividend and append it to 33, then repeat: 332 / 397

Step 3:
When dividing 332 by 397, we get 0 with a remainder of 332.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 332, we get 332.
Include the next digit (6) from the dividend after 332, then repeat: 3326 / 397

Going ahead to step 4:
The number 397 fits into 3326 8 times, leaving a remainder of 150.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 3176 away from 3326, we end up with 150.
Grab the next digit (1) from the dividend, add it to 150, then carry on: 1501 / 397

Going ahead to step 5:
The number 397 fits into 1501 3 times, leaving a remainder of 310.
The next digit of our result is 3. 
Result so far: 83.0
If we subtract 1191 from 1501, we get 310.
Include the next digit (9) from the dividend after 310, then repeat: 3109 / 397

Step 6:
When dividing 3109 by 397, we get 7 with a remainder of 330.
Write down 7 as next digit of the result. 
Result so far: 837.0
Subtract 2779 from 3109 to get 330.
Append the next digit (6) from the dividend to 330 and continue with: 3306 / 397

Going ahead to step 7:
397 goes into 3306 8 times with a remainder of 130.
Record the quotient 8 as the next digit in the result. 
Result so far: 8378.0
The remainder is 130 after subtracting 3176 from 3306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 8:
If we divide 1300 by 397, we get 3 and a remainder of 109.
Record the quotient 3 as the next digit in the result. 
Result so far: 8378.3
If we take 1191 away from 1300, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 9:
397 goes into 1090 2 times with a remainder of 296.
Put 2 as the next digit of the answer. 
Result so far: 8378.32
Subtracting 794 from 1090 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 10:
If we divide 2960 by 397, we get 7 and a remainder of 181.
Use 7 as the next digit of our solution. 
Result so far: 8378.327
If we take 2779 away from 2960, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 11:
The number 397 fits into 1810 4 times, leaving a remainder of 222.
Use 4 as the next digit of our solution. 
Result so far: 8378.3274
The remainder is 222 after subtracting 1588 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 12:
If we divide 2220 by 397, we get 5 and a remainder of 235.
The next digit of our result is 5. 
Result so far: 8378.32745
The remainder is 235 after subtracting 1985 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 13:
397 goes into 2350 5 times with a remainder of 365.
Put 5 as the next digit of the answer. 
Result so far: 8378.327455
If we subtract 1985 from 2350, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

The final outcome is 8378.327455, with a leftover of 3.65e-05.
