We look at the division of 78129384 by 946 
We want to divide 78129384 by 946.

Advancing to step 1:
When dividing 7 by 946, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 946

Step 2:
946 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 946

Moving on to step 3:
946 can be fit into 781 0 times, resulting in a remainder of 781.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 781 and we're left with 781.
Bring next digit (2) of the dividend behind the 781 and repeat the process: 7812 / 946

Moving on to step 4:
7812 divided by 946 is 8 with a remainder of 244.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 7568 from 7812 to get 244.
Fetch the next digit (9) from the dividend, attach it to 244 and continue: 2449 / 946

Let's proceed to step 5:
When dividing 2449 by 946, we get 2 with a remainder of 557.
The next digit of our result is 2. 
Result so far: 82.0
Deduct 1892 from 2449 and we're left with 557.
Take the next digit (3) from the dividend and append it to 557, then repeat: 5573 / 946

Let's proceed to step 6:
5573 divided by 946 is 5 with a remainder of 843.
The number 5 becomes the next digit in our result. 
Result so far: 825.0
Deduct 4730 from 5573 and we're left with 843.
Bring next digit (8) of the dividend behind the 843 and repeat the process: 8438 / 946

Moving on to step 7:
If we divide 8438 by 946, we get 8 and a remainder of 870.
The number 8 becomes the next digit in our result. 
Result so far: 8258.0
Deduct 7568 from 8438 and we're left with 870.
Grab the next digit (4) from the dividend, add it to 870, then carry on: 8704 / 946

Let's proceed to step 8:
8704 divided by 946 is 9 with a remainder of 190.
Write down 9 as next digit of the result. 
Result so far: 82589.0
If we subtract 8514 from 8704, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 9:
1900 divided by 946 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 82589.2
The remainder is 8 after subtracting 1892 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
If we divide 80 by 946, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 82589.2
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
The number 946 fits into 800 0 times, leaving a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 82589.2
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The quotient of the division is 82589.2, and the remainder is 0.08.
