We look at the division of 78945410 by 947 
We want to divide 78945410 by 947.

Step 1:
When dividing 7 by 947, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 947

Step 2:
78 divided by 947 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 947

Going ahead to step 3:
The number 947 fits into 789 0 times, leaving a remainder of 789.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 789 after subtracting 0 from 789.
Bring next digit (4) of the dividend behind the 789 and repeat the process: 7894 / 947

Step 4:
If we divide 7894 by 947, we get 8 and a remainder of 318.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 318 after subtracting 7576 from 7894.
Append the next digit (5) from the dividend to 318 and continue with: 3185 / 947

On to step 5:
The number 947 fits into 3185 3 times, leaving a remainder of 344.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
If we subtract 2841 from 3185, we get 344.
Bring next digit (4) of the dividend behind the 344 and repeat the process: 3444 / 947

Advancing to step 6:
The number 947 fits into 3444 3 times, leaving a remainder of 603.
Put 3 as the next digit of the answer. 
Result so far: 833.0
Subtract 2841 from 3444 to get 603.
Append the next digit (1) from the dividend to 603 and continue with: 6031 / 947

Advancing to step 7:
The number 947 fits into 6031 6 times, leaving a remainder of 349.
Record the quotient 6 as the next digit in the result. 
Result so far: 8336.0
Subtracting 5682 from 6031 leaves us with 349.
Grab the next digit (0) from the dividend, add it to 349, then carry on: 3490 / 947

Advancing to step 8:
3490 divided by 947 is 3 with a remainder of 649.
Record the quotient 3 as the next digit in the result. 
Result so far: 83363.0
Subtract 2841 from 3490 to get 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Moving on to step 9:
6490 divided by 947 is 6 with a remainder of 808.
The next digit of our result is 6. 
Result so far: 83363.6
If we take 5682 away from 6490, we end up with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Step 10:
947 can be fit into 8080 8 times, resulting in a remainder of 504.
Use 8 as the next digit of our solution. 
Result so far: 83363.68
Deduct 7576 from 8080 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 11:
5040 divided by 947 is 5 with a remainder of 305.
Use 5 as the next digit of our solution. 
Result so far: 83363.685
If we take 4735 away from 5040, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 12:
The number 947 fits into 3050 3 times, leaving a remainder of 209.
Write down 3 as next digit of the result. 
Result so far: 83363.6853
If we take 2841 away from 3050, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 13:
The number 947 fits into 2090 2 times, leaving a remainder of 196.
Put 2 as the next digit of the answer. 
Result so far: 83363.68532
Subtracting 1894 from 2090 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 14:
947 can be fit into 1960 2 times, resulting in a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 83363.685322
Deduct 1894 from 1960 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The quotient of the division is 83363.685322, and the remainder is 6.6e-06.
