We're dividing 643017 by 46 
The aim is to understand the frequency of 46 in 643017.

Advancing to step 1:
46 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 46

Going ahead to step 2:
64 divided by 46 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 46 away from 64, we end up with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 46

On to step 3:
46 goes into 183 3 times with a remainder of 45.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 138 from 183 leaves us with 45.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 46

On to step 4:
When dividing 450 by 46, we get 9 with a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
The remainder is 36 after subtracting 414 from 450.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 46

Moving on to step 5:
If we divide 361 by 46, we get 7 and a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 1397.0
If we subtract 322 from 361, we get 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 46

Going ahead to step 6:
46 can be fit into 397 8 times, resulting in a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 13978.0
Subtract 368 from 397 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
290 divided by 46 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 13978.6
Deduct 276 from 290 and we're left with 14.
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:
When dividing 140 by 46, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 13978.63
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.

On to step 9:
20 divided by 46 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 13978.63
Subtract 0 from 20 to get 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:
When dividing 200 by 46, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 13978.6304
If we take 184 away from 200, we end up 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.

Moving on to step 11:
If we divide 160 by 46, we get 3 and a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 13978.63043
If we take 138 away from 160, we end up 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.

On to step 12:
220 divided by 46 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 13978.630434
Subtract 184 from 220 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
When dividing 360 by 46, we get 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 13978.6304347
Subtracting 322 from 360 leaves us 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.

Moving on to step 14:
When dividing 380 by 46, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 13978.63043478
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.

The final result is 13978.63043478 with a remainder of 1.2e-08.
