143972 divided by 46 
The aim is to understand the frequency of 46 in 143972.

Step 1:
46 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 46

Advancing to step 2:
46 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 46

Going ahead to step 3:
46 can be fit into 143 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 138 from 143 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 46

Advancing to step 4:
If we divide 59 by 46, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 13 after subtracting 46 from 59.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 46

Let's proceed to step 5:
137 divided by 46 is 2 with a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 312.0
Subtracting 92 from 137 leaves us with 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 46

Step 6:
The number 46 fits into 452 9 times, leaving a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 3129.0
If we take 414 away from 452, 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.

Step 7:
The number 46 fits into 380 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 3129.8
Deduct 368 from 380 and we're left 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.

Advancing to step 8:
46 goes into 120 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 3129.82
Subtracting 92 from 120 leaves us 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.

Let's proceed to step 9:
When dividing 280 by 46, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 3129.826
Subtract 276 from 280 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
When dividing 40 by 46, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3129.826
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
If we divide 400 by 46, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 3129.82608
If we subtract 368 from 400, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
46 goes into 320 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 3129.826086
Subtracting 276 from 320 leaves us 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.

Advancing to step 13:
440 divided by 46 is 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 3129.8260869
The remainder is 26 after subtracting 414 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
260 divided by 46 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 3129.82608695
Deduct 230 from 260 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 3129.82608695, and the remainder is 3e-08.
