1644666 ÷ 47 
The aim is to understand the frequency of 47 in 1644666.

Advancing to step 1:
47 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 47

Step 2:
The number 47 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 47

On to step 3:
47 can be fit into 164 3 times, resulting in a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 141 from 164 to get 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 47

Moving on to step 4:
The number 47 fits into 234 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 188 from 234, we get 46.
Take the next digit (6) from the dividend and append it to 46, then repeat: 466 / 47

On to step 5:
466 divided by 47 is 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 349.0
Deduct 423 from 466 and we're left with 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 47

Step 6:
If we divide 436 by 47, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 3499.0
Deduct 423 from 436 and we're left with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 47

Advancing to step 7:
When dividing 136 by 47, we get 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 34992.0
Subtracting 94 from 136 leaves us 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.

Moving on to step 8:
When dividing 420 by 47, we get 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 34992.8
Deduct 376 from 420 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.

Advancing to step 9:
47 goes into 440 9 times with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 34992.89
If we subtract 423 from 440, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
If we divide 170 by 47, we get 3 and a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 34992.893
The remainder is 29 after subtracting 141 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
The number 47 fits into 290 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 34992.8936
If we subtract 282 from 290, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
47 goes into 80 1 times with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 34992.89361
Subtract 47 from 80 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
The number 47 fits into 330 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 34992.893617
Deduct 329 from 330 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
When dividing 10 by 47, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 34992.893617
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
If we divide 100 by 47, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 34992.89361702
The remainder is 6 after subtracting 94 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 34992.89361702, with a leftover of 6e-09.
