646858 ÷ 46 
The aim is to understand the frequency of 46 in 646858.

On to step 1:
6 divided by 46 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 46

On to step 2:
46 goes into 64 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
If we take 46 away from 64, we end up with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 46

On to step 3:
When dividing 186 by 46, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 184 from 186 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 46

Advancing to step 4:
If we divide 28 by 46, we get 0 and a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
The remainder is 28 after subtracting 0 from 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 46

Moving on to step 5:
285 divided by 46 is 6 with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 1406.0
The remainder is 9 after subtracting 276 from 285.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 46

Moving on to step 6:
The number 46 fits into 98 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 14062.0
If we take 92 away from 98, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
46 goes into 60 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 14062.1
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
140 divided by 46 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 14062.13
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
The number 46 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 14062.13
If we take 0 away from 20, we end up 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 10:
46 goes into 200 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 14062.1304
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
46 can be fit into 160 3 times, resulting in a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 14062.13043
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
The number 46 fits into 220 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 14062.130434
Deduct 184 from 220 and we're left 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.

Let's proceed to step 13:
360 divided by 46 is 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 14062.1304347
If we take 322 away from 360, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
380 divided by 46 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 14062.13043478
The remainder is 12 after subtracting 368 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 14062.13043478, with a leftover of 1.2e-08.
