We look at the division of 1281061 by 394 
The aim is to understand the frequency of 394 in 1281061.

On to step 1:
1 divided by 394 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 394

Step 2:
394 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 394

Step 3:
The number 394 fits into 128 0 times, leaving a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 128 and we're left with 128.
Bring next digit (1) of the dividend behind the 128 and repeat the process: 1281 / 394

Moving on to step 4:
1281 divided by 394 is 3 with a remainder of 99.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 99 after subtracting 1182 from 1281.
Include the next digit (0) from the dividend after 99, then repeat: 990 / 394

Moving on to step 5:
If we divide 990 by 394, we get 2 and a remainder of 202.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we take 788 away from 990, we end up with 202.
Bring next digit (6) of the dividend behind the 202 and repeat the process: 2026 / 394

Step 6:
If we divide 2026 by 394, we get 5 and a remainder of 56.
The number 5 becomes the next digit in our result. 
Result so far: 325.0
If we subtract 1970 from 2026, we get 56.
Take the next digit (1) from the dividend and append it to 56, then repeat: 561 / 394

Step 7:
561 divided by 394 is 1 with a remainder of 167.
Put 1 as the next digit of the answer. 
Result so far: 3251.0
Subtracting 394 from 561 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 8:
1670 divided by 394 is 4 with a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 3251.4
Subtract 1576 from 1670 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 9:
The number 394 fits into 940 2 times, leaving a remainder of 152.
Put 2 as the next digit of the answer. 
Result so far: 3251.42
Subtracting 788 from 940 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 10:
1520 divided by 394 is 3 with a remainder of 338.
The next digit of our result is 3. 
Result so far: 3251.423
If we take 1182 away from 1520, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 11:
394 can be fit into 3380 8 times, resulting in a remainder of 228.
Record the quotient 8 as the next digit in the result. 
Result so far: 3251.4238
The remainder is 228 after subtracting 3152 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 12:
394 can be fit into 2280 5 times, resulting in a remainder of 310.
Write down 5 as next digit of the result. 
Result so far: 3251.42385
The remainder is 310 after subtracting 1970 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 13:
If we divide 3100 by 394, we get 7 and a remainder of 342.
Use 7 as the next digit of our solution. 
Result so far: 3251.423857
The remainder is 342 after subtracting 2758 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 14:
The number 394 fits into 3420 8 times, leaving a remainder of 268.
The next digit of our result is 8. 
Result so far: 3251.4238578
The remainder is 268 after subtracting 3152 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 15:
When dividing 2680 by 394, we get 6 with a remainder of 316.
Use 6 as the next digit of our solution. 
Result so far: 3251.42385786
Subtract 2364 from 2680 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

The quotient of the division is 3251.42385786, and the remainder is 3.16e-07.
