We're dividing 41681671 by 394 
The aim is to understand the frequency of 394 in 41681671.

Going ahead to step 1:
When dividing 4 by 394, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 394

Moving on to step 2:
394 can be fit into 41 0 times, resulting in a remainder of 41.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Append the next digit (6) from the dividend to 41 and continue with: 416 / 394

Going ahead to step 3:
394 can be fit into 416 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 22 after subtracting 394 from 416.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 394

Advancing to step 4:
When dividing 228 by 394, we get 0 with a remainder of 228.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 228, we end up with 228.
Grab the next digit (1) from the dividend, add it to 228, then carry on: 2281 / 394

Advancing to step 5:
394 can be fit into 2281 5 times, resulting in a remainder of 311.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtract 1970 from 2281 to get 311.
Fetch the next digit (6) from the dividend, attach it to 311 and continue: 3116 / 394

Step 6:
394 can be fit into 3116 7 times, resulting in a remainder of 358.
The number 7 becomes the next digit in our result. 
Result so far: 1057.0
Subtract 2758 from 3116 to get 358.
Grab the next digit (7) from the dividend, add it to 358, then carry on: 3587 / 394

Going ahead to step 7:
394 goes into 3587 9 times with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 10579.0
Subtract 3546 from 3587 to get 41.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 394

Going ahead to step 8:
The number 394 fits into 411 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 105791.0
If we take 394 away from 411, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
170 divided by 394 is 0 with a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 105791.0
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 10:
1700 divided by 394 is 4 with a remainder of 124.
Use 4 as the next digit of our solution. 
Result so far: 105791.04
If we take 1576 away from 1700, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 11:
If we divide 1240 by 394, we get 3 and a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 105791.043
Subtracting 1182 from 1240 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
394 goes into 580 1 times with a remainder of 186.
Record the quotient 1 as the next digit in the result. 
Result so far: 105791.0431
Subtract 394 from 580 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 13:
394 goes into 1860 4 times with a remainder of 284.
Use 4 as the next digit of our solution. 
Result so far: 105791.04314
Subtract 1576 from 1860 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 14:
If we divide 2840 by 394, we get 7 and a remainder of 82.
Record the quotient 7 as the next digit in the result. 
Result so far: 105791.043147
If we take 2758 away from 2840, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 15:
820 divided by 394 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 105791.0431472
Deduct 788 from 820 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 16:
394 goes into 320 0 times with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 105791.0431472
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 105791.0431472 with a remainder of 3.2e-07.
