We divide 640410 by 46
The aim is to understand the frequency of 46 in 640410.

On to step 1:
The number 46 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 46

On to step 2:
The number 46 fits into 64 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 46 from 64 leaves us with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 46

Moving on to step 3:
180 divided by 46 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 42 after subtracting 138 from 180.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 46

Going ahead to step 4:
When dividing 424 by 46, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we subtract 414 from 424, we get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 46

On to step 5:
The number 46 fits into 101 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 1392.0
Deduct 92 from 101 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 46

Let's proceed to step 6:
If we divide 90 by 46, we get 1 and a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 13921.0
Deduct 46 from 90 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
When dividing 440 by 46, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 13921.9
Subtract 414 from 440 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
The number 46 fits into 260 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 13921.95
Subtract 230 from 260 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
If we divide 300 by 46, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 13921.956
If we subtract 276 from 300, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
46 goes into 240 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 13921.9565
Subtract 230 from 240 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 46 fits into 100 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 13921.95652
If we take 92 away from 100, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
46 can be fit into 80 1 times, resulting in a remainder of 34.
The next digit of our result is 1. 
Result so far: 13921.956521
Subtract 46 from 80 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
340 divided by 46 is 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 13921.9565217
Deduct 322 from 340 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
180 divided by 46 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 13921.95652173
If we take 138 away from 180, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 13921.95652173 with a remaining 4.2e-08.
