391894 divided by 46 
The aim is to understand the frequency of 46 in 391894.

Going ahead to step 1:
If we divide 3 by 46, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 46

Advancing to step 2:
39 divided by 46 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 46

Moving on to step 3:
46 goes into 391 8 times with a remainder of 23.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 368 from 391 to get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 46

Advancing to step 4:
238 divided by 46 is 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
The remainder is 8 after subtracting 230 from 238.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 46

On to step 5:
46 can be fit into 89 1 times, resulting in a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 851.0
Deduct 46 from 89 and we're left with 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 46

Let's proceed to step 6:
46 goes into 434 9 times with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 8519.0
Deduct 414 from 434 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
200 divided by 46 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 8519.4
Subtracting 184 from 200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
46 goes into 160 3 times with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 8519.43
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
If we divide 220 by 46, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 8519.434
Subtracting 184 from 220 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
When dividing 360 by 46, we get 7 with a remainder of 38.
The next digit of our result is 7. 
Result so far: 8519.4347
The remainder is 38 after subtracting 322 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
380 divided by 46 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8519.43478
Subtracting 368 from 380 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
120 divided by 46 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 8519.434782
If we take 92 away from 120, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
46 goes into 280 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 8519.4347826
If we take 276 away from 280, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
40 divided by 46 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8519.4347826
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 8519.4347826 with a remainder of 4e-08.
