78440381 ÷ 947 
The aim is to understand the frequency of 947 in 78440381.

Moving on to step 1:
If we divide 7 by 947, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 947

Moving on to step 2:
The number 947 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 947

Moving on to step 3:
The number 947 fits into 784 0 times, leaving a remainder of 784.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 784, we end up with 784.
Bring next digit (4) of the dividend behind the 784 and repeat the process: 7844 / 947

On to step 4:
7844 divided by 947 is 8 with a remainder of 268.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 7576 away from 7844, we end up with 268.
Fetch the next digit (0) from the dividend, attach it to 268 and continue: 2680 / 947

Step 5:
2680 divided by 947 is 2 with a remainder of 786.
The next digit of our result is 2. 
Result so far: 82.0
Subtracting 1894 from 2680 leaves us with 786.
Take the next digit (3) from the dividend and append it to 786, then repeat: 7863 / 947

Going ahead to step 6:
If we divide 7863 by 947, we get 8 and a remainder of 287.
The number 8 becomes the next digit in our result. 
Result so far: 828.0
Subtract 7576 from 7863 to get 287.
Grab the next digit (8) from the dividend, add it to 287, then carry on: 2878 / 947

Going ahead to step 7:
When dividing 2878 by 947, we get 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 8283.0
If we take 2841 away from 2878, we end up with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 947

Advancing to step 8:
If we divide 371 by 947, we get 0 and a remainder of 371.
The number 0 becomes the next digit in our result. 
Result so far: 82830.0
If we subtract 0 from 371, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Let's proceed to step 9:
When dividing 3710 by 947, we get 3 with a remainder of 869.
Record the quotient 3 as the next digit in the result. 
Result so far: 82830.3
Subtracting 2841 from 3710 leaves us with 869.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8690, and continue the process.

Moving on to step 10:
If we divide 8690 by 947, we get 9 and a remainder of 167.
The number 9 becomes the next digit in our result. 
Result so far: 82830.39
Subtract 8523 from 8690 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 11:
947 can be fit into 1670 1 times, resulting in a remainder of 723.
The number 1 becomes the next digit in our result. 
Result so far: 82830.391
If we take 947 away from 1670, we end up with 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Step 12:
7230 divided by 947 is 7 with a remainder of 601.
The number 7 becomes the next digit in our result. 
Result so far: 82830.3917
The remainder is 601 after subtracting 6629 from 7230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

On to step 13:
947 goes into 6010 6 times with a remainder of 328.
The next digit of our result is 6. 
Result so far: 82830.39176
The remainder is 328 after subtracting 5682 from 6010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 14:
947 can be fit into 3280 3 times, resulting in a remainder of 439.
Put 3 as the next digit of the answer. 
Result so far: 82830.391763
Subtracting 2841 from 3280 leaves us with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Let's proceed to step 15:
The number 947 fits into 4390 4 times, leaving a remainder of 602.
The number 4 becomes the next digit in our result. 
Result so far: 82830.3917634
Deduct 3788 from 4390 and we're left with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Moving on to step 16:
When dividing 6020 by 947, we get 6 with a remainder of 338.
Put 6 as the next digit of the answer. 
Result so far: 82830.39176346
Subtract 5682 from 6020 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

In conclusion, the division gives 82830.39176346 with a balance of 3.38e-07.
