Let's divide 78928614 by 978
Our goal is to divide 78928614 by 978.

Advancing to step 1:
When dividing 7 by 978, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 978

Step 2:
If we divide 78 by 978, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 978

On to step 3:
If we divide 789 by 978, we get 0 and a remainder of 789.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 789 after subtracting 0 from 789.
Include the next digit (2) from the dividend after 789, then repeat: 7892 / 978

Let's proceed to step 4:
If we divide 7892 by 978, we get 8 and a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 7824 from 7892 to get 68.
Take the next digit (8) from the dividend and append it to 68, then repeat: 688 / 978

Moving on to step 5:
If we divide 688 by 978, we get 0 and a remainder of 688.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Deduct 0 from 688 and we're left with 688.
Fetch the next digit (6) from the dividend, attach it to 688 and continue: 6886 / 978

Advancing to step 6:
When dividing 6886 by 978, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 807.0
Deduct 6846 from 6886 and we're left with 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 978

On to step 7:
When dividing 401 by 978, we get 0 with a remainder of 401.
Put 0 as the next digit of the answer. 
Result so far: 8070.0
Subtract 0 from 401 to get 401.
Take the next digit (4) from the dividend and append it to 401, then repeat: 4014 / 978

Step 8:
978 can be fit into 4014 4 times, resulting in a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 80704.0
The remainder is 102 after subtracting 3912 from 4014.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 9:
When dividing 1020 by 978, we get 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 80704.1
Subtract 978 from 1020 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
978 goes into 420 0 times with a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 80704.1
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 11:
978 can be fit into 4200 4 times, resulting in a remainder of 288.
Write down 4 as next digit of the result. 
Result so far: 80704.104
Deduct 3912 from 4200 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 12:
978 goes into 2880 2 times with a remainder of 924.
The number 2 becomes the next digit in our result. 
Result so far: 80704.1042
If we take 1956 away from 2880, we end up with 924.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9240, and continue the process.

Going ahead to step 13:
When dividing 9240 by 978, we get 9 with a remainder of 438.
The next digit of our result is 9. 
Result so far: 80704.10429
The remainder is 438 after subtracting 8802 from 9240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

On to step 14:
978 goes into 4380 4 times with a remainder of 468.
The next digit of our result is 4. 
Result so far: 80704.104294
The remainder is 468 after subtracting 3912 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 15:
When dividing 4680 by 978, we get 4 with a remainder of 768.
The number 4 becomes the next digit in our result. 
Result so far: 80704.1042944
If we subtract 3912 from 4680, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

The final outcome is 80704.1042944, with a leftover of 7.68e-06.
