Let's divide 16639924 by 847
The aim is to understand the frequency of 847 in 16639924.

On to step 1:
847 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 847

Step 2:
847 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 847

Let's proceed to step 3:
If we divide 166 by 847, we get 0 and a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 166, we end up with 166.
Fetch the next digit (3) from the dividend, attach it to 166 and continue: 1663 / 847

Moving on to step 4:
1663 divided by 847 is 1 with a remainder of 816.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 847 from 1663 and we're left with 816.
Fetch the next digit (9) from the dividend, attach it to 816 and continue: 8169 / 847

On to step 5:
847 goes into 8169 9 times with a remainder of 546.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 7623 from 8169 and we're left with 546.
Take the next digit (9) from the dividend and append it to 546, then repeat: 5469 / 847

Going ahead to step 6:
When dividing 5469 by 847, we get 6 with a remainder of 387.
Put 6 as the next digit of the answer. 
Result so far: 196.0
If we subtract 5082 from 5469, we get 387.
Append the next digit (2) from the dividend to 387 and continue with: 3872 / 847

Advancing to step 7:
When dividing 3872 by 847, we get 4 with a remainder of 484.
Use 4 as the next digit of our solution. 
Result so far: 1964.0
Deduct 3388 from 3872 and we're left with 484.
Take the next digit (4) from the dividend and append it to 484, then repeat: 4844 / 847

Advancing to step 8:
If we divide 4844 by 847, we get 5 and a remainder of 609.
The number 5 becomes the next digit in our result. 
Result so far: 19645.0
Subtract 4235 from 4844 to get 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Going ahead to step 9:
847 can be fit into 6090 7 times, resulting in a remainder of 161.
Put 7 as the next digit of the answer. 
Result so far: 19645.7
Deduct 5929 from 6090 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 10:
847 goes into 1610 1 times with a remainder of 763.
Use 1 as the next digit of our solution. 
Result so far: 19645.71
If we subtract 847 from 1610, we get 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

Going ahead to step 11:
If we divide 7630 by 847, we get 9 and a remainder of 7.
The next digit of our result is 9. 
Result so far: 19645.719
Subtracting 7623 from 7630 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
70 divided by 847 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 19645.719
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
When dividing 700 by 847, we get 0 with a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 19645.719
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The quotient of the division is 19645.719, and the remainder is 0.0007.
