We look at the division of 63959131 by 947 
The aim is to understand the frequency of 947 in 63959131.

Advancing to step 1:
947 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 947

Step 2:
947 goes into 63 0 times with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 947

Going ahead to step 3:
If we divide 639 by 947, we get 0 and a remainder of 639.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 639 after subtracting 0 from 639.
Include the next digit (5) from the dividend after 639, then repeat: 6395 / 947

Let's proceed to step 4:
947 can be fit into 6395 6 times, resulting in a remainder of 713.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 713 after subtracting 5682 from 6395.
Append the next digit (9) from the dividend to 713 and continue with: 7139 / 947

Advancing to step 5:
7139 divided by 947 is 7 with a remainder of 510.
The next digit of our result is 7. 
Result so far: 67.0
The remainder is 510 after subtracting 6629 from 7139.
Append the next digit (1) from the dividend to 510 and continue with: 5101 / 947

Let's proceed to step 6:
5101 divided by 947 is 5 with a remainder of 366.
The number 5 becomes the next digit in our result. 
Result so far: 675.0
Subtracting 4735 from 5101 leaves us with 366.
Fetch the next digit (3) from the dividend, attach it to 366 and continue: 3663 / 947

Advancing to step 7:
947 can be fit into 3663 3 times, resulting in a remainder of 822.
Record the quotient 3 as the next digit in the result. 
Result so far: 6753.0
Deduct 2841 from 3663 and we're left with 822.
Bring next digit (1) of the dividend behind the 822 and repeat the process: 8221 / 947

Moving on to step 8:
When dividing 8221 by 947, we get 8 with a remainder of 645.
Use 8 as the next digit of our solution. 
Result so far: 67538.0
Subtract 7576 from 8221 to get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Step 9:
When dividing 6450 by 947, we get 6 with a remainder of 768.
Put 6 as the next digit of the answer. 
Result so far: 67538.6
If we take 5682 away from 6450, we end up with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Moving on to step 10:
If we divide 7680 by 947, we get 8 and a remainder of 104.
Write down 8 as next digit of the result. 
Result so far: 67538.68
Deduct 7576 from 7680 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 11:
1040 divided by 947 is 1 with a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 67538.681
The remainder is 93 after subtracting 947 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 12:
930 divided by 947 is 0 with a remainder of 930.
Write down 0 as next digit of the result. 
Result so far: 67538.681
Subtracting 0 from 930 leaves us with 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9300, and continue the process.

Moving on to step 13:
When dividing 9300 by 947, we get 9 with a remainder of 777.
Put 9 as the next digit of the answer. 
Result so far: 67538.68109
If we subtract 8523 from 9300, we get 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Step 14:
If we divide 7770 by 947, we get 8 and a remainder of 194.
The next digit of our result is 8. 
Result so far: 67538.681098
Deduct 7576 from 7770 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 15:
1940 divided by 947 is 2 with a remainder of 46.
The next digit of our result is 2. 
Result so far: 67538.6810982
Deduct 1894 from 1940 and we're left 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 16:
When dividing 460 by 947, we get 0 with a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 67538.6810982
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

After the division, we end up with 67538.6810982 and a remainder of 4.6e-07.
