661987 ÷ 47 
The aim is to understand the frequency of 47 in 661987.

Moving on to step 1:
47 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.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 47

Let's proceed to step 2:
If we divide 66 by 47, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 47 from 66 to get 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 47

Step 3:
191 divided by 47 is 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 3 after subtracting 188 from 191.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 47

Going ahead to step 4:
If we divide 39 by 47, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 47

Advancing to step 5:
If we divide 398 by 47, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 1408.0
Deduct 376 from 398 and we're left with 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 47

Let's proceed to step 6:
The number 47 fits into 227 4 times, leaving a remainder of 39.
The next digit of our result is 4. 
Result so far: 14084.0
Subtract 188 from 227 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
When dividing 390 by 47, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 14084.8
The remainder is 14 after subtracting 376 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
The number 47 fits into 140 2 times, leaving a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 14084.82
Subtract 94 from 140 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
47 goes into 460 9 times with a remainder of 37.
The next digit of our result is 9. 
Result so far: 14084.829
If we subtract 423 from 460, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 10:
370 divided by 47 is 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 14084.8297
Subtract 329 from 370 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 11:
If we divide 410 by 47, we get 8 and a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 14084.82978
If we take 376 away from 410, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
47 can be fit into 340 7 times, resulting in a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 14084.829787
The remainder is 11 after subtracting 329 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
When dividing 110 by 47, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 14084.8297872
Deduct 94 from 110 and we're left 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.

Step 14:
When dividing 160 by 47, we get 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 14084.82978723
If we subtract 141 from 160, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 14084.82978723 with a balance of 1.9e-08.
