638237 ÷ 47 
The aim is to understand the frequency of 47 in 638237.

Let's proceed to step 1:
The number 47 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 47

Going ahead to step 2:
63 divided by 47 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 16 after subtracting 47 from 63.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 47

Step 3:
47 can be fit into 168 3 times, resulting in a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 141 from 168 to get 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 47

Advancing to step 4:
When dividing 272 by 47, we get 5 with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
If we subtract 235 from 272, we get 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 47

Step 5:
If we divide 373 by 47, we get 7 and a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 1357.0
If we subtract 329 from 373, we get 44.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 47

Step 6:
If we divide 447 by 47, we get 9 and a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 13579.0
If we take 423 away from 447, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
47 can be fit into 240 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 13579.5
Subtract 235 from 240 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
47 goes into 50 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 13579.51
Deduct 47 from 50 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
The number 47 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 13579.51
Subtract 0 from 30 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.

Let's proceed to step 10:
47 goes into 300 6 times with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 13579.5106
Subtract 282 from 300 to get 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 11:
47 goes into 180 3 times with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 13579.51063
If we take 141 away from 180, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 12:
If we divide 390 by 47, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 13579.510638
If we take 376 away from 390, we end up 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.

Moving on to step 13:
140 divided by 47 is 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 13579.5106382
Subtracting 94 from 140 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
47 goes into 460 9 times with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 13579.51063829
The remainder is 37 after subtracting 423 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

In conclusion, the division gives 13579.51063829 with a balance of 3.7e-08.
