139839 divided by 46 
The aim is to understand the frequency of 46 in 139839.

On to step 1:
46 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 46

Moving on to step 2:
If we divide 13 by 46, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 46

Let's proceed to step 3:
46 goes into 139 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 138 from 139, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 46

Advancing to step 4:
46 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 46

Advancing to step 5:
The number 46 fits into 183 3 times, leaving a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 303.0
If we subtract 138 from 183, we get 45.
Take the next digit (9) from the dividend and append it to 45, then repeat: 459 / 46

Advancing to step 6:
The number 46 fits into 459 9 times, leaving a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 3039.0
The remainder is 45 after subtracting 414 from 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
46 can be fit into 450 9 times, resulting in a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 3039.9
The remainder is 36 after subtracting 414 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
360 divided by 46 is 7 with a remainder of 38.
The next digit of our result is 7. 
Result so far: 3039.97
The remainder is 38 after subtracting 322 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
46 goes into 380 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 3039.978
If we take 368 away from 380, we end up 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.

On to step 10:
The number 46 fits into 120 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 3039.9782
If we take 92 away from 120, we end up 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.

Advancing to step 11:
280 divided by 46 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 3039.97826
The remainder is 4 after subtracting 276 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
The number 46 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3039.97826
Deduct 0 from 40 and we're left with 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 13:
The number 46 fits into 400 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 3039.9782608
Deduct 368 from 400 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
320 divided by 46 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 3039.97826086
Deduct 276 from 320 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.

The quotient of the division is 3039.97826086, and the remainder is 4.4e-08.
