46691846 ÷ 398 
The aim is to understand the frequency of 398 in 46691846.

On to step 1:
398 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 398

On to step 2:
When dividing 46 by 398, we get 0 with a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 46 and we're left with 46.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 398

Moving on to step 3:
When dividing 466 by 398, we get 1 with a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 398 from 466 and we're left with 68.
Fetch the next digit (9) from the dividend, attach it to 68 and continue: 689 / 398

Let's proceed to step 4:
689 divided by 398 is 1 with a remainder of 291.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 398 from 689, we get 291.
Include the next digit (1) from the dividend after 291, then repeat: 2911 / 398

Let's proceed to step 5:
398 goes into 2911 7 times with a remainder of 125.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Subtracting 2786 from 2911 leaves us with 125.
Grab the next digit (8) from the dividend, add it to 125, then carry on: 1258 / 398

Advancing to step 6:
The number 398 fits into 1258 3 times, leaving a remainder of 64.
The next digit of our result is 3. 
Result so far: 1173.0
Subtract 1194 from 1258 to get 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 398

Moving on to step 7:
398 can be fit into 644 1 times, resulting in a remainder of 246.
Record the quotient 1 as the next digit in the result. 
Result so far: 11731.0
The remainder is 246 after subtracting 398 from 644.
Fetch the next digit (6) from the dividend, attach it to 246 and continue: 2466 / 398

On to step 8:
2466 divided by 398 is 6 with a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 117316.0
Subtracting 2388 from 2466 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
780 divided by 398 is 1 with a remainder of 382.
Put 1 as the next digit of the answer. 
Result so far: 117316.1
The remainder is 382 after subtracting 398 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 10:
398 can be fit into 3820 9 times, resulting in a remainder of 238.
Record the quotient 9 as the next digit in the result. 
Result so far: 117316.19
Deduct 3582 from 3820 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 11:
398 goes into 2380 5 times with a remainder of 390.
Write down 5 as next digit of the result. 
Result so far: 117316.195
If we subtract 1990 from 2380, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 12:
398 goes into 3900 9 times with a remainder of 318.
The number 9 becomes the next digit in our result. 
Result so far: 117316.1959
The remainder is 318 after subtracting 3582 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 13:
398 can be fit into 3180 7 times, resulting in a remainder of 394.
Put 7 as the next digit of the answer. 
Result so far: 117316.19597
Deduct 2786 from 3180 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 14:
The number 398 fits into 3940 9 times, leaving a remainder of 358.
The next digit of our result is 9. 
Result so far: 117316.195979
If we take 3582 away from 3940, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 15:
3580 divided by 398 is 8 with a remainder of 396.
Put 8 as the next digit of the answer. 
Result so far: 117316.1959798
Deduct 3184 from 3580 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 16:
When dividing 3960 by 398, we get 9 with a remainder of 378.
Record the quotient 9 as the next digit in the result. 
Result so far: 117316.19597989
Deduct 3582 from 3960 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

In conclusion, the division gives 117316.19597989 with a balance of 3.78e-07.
