Let's divide 19645770 by 978
We want to figure out the number of times 19645770 can be divided by 978.

Step 1:
1 divided by 978 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 978

Step 2:
If we divide 19 by 978, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 978

On to step 3:
196 divided by 978 is 0 with a remainder of 196.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 196 after subtracting 0 from 196.
Take the next digit (4) from the dividend and append it to 196, then repeat: 1964 / 978

Advancing to step 4:
When dividing 1964 by 978, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1956 from 1964, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 978

Moving on to step 5:
978 can be fit into 85 0 times, resulting in a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 85 to get 85.
Append the next digit (7) from the dividend to 85 and continue with: 857 / 978

Step 6:
978 can be fit into 857 0 times, resulting in a remainder of 857.
Write down 0 as next digit of the result. 
Result so far: 200.0
If we subtract 0 from 857, we get 857.
Bring next digit (7) of the dividend behind the 857 and repeat the process: 8577 / 978

Step 7:
8577 divided by 978 is 8 with a remainder of 753.
Use 8 as the next digit of our solution. 
Result so far: 2008.0
Deduct 7824 from 8577 and we're left with 753.
Take the next digit (0) from the dividend and append it to 753, then repeat: 7530 / 978

Let's proceed to step 8:
978 can be fit into 7530 7 times, resulting in a remainder of 684.
Record the quotient 7 as the next digit in the result. 
Result so far: 20087.0
Deduct 6846 from 7530 and we're left with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Going ahead to step 9:
6840 divided by 978 is 6 with a remainder of 972.
Write down 6 as next digit of the result. 
Result so far: 20087.6
Deduct 5868 from 6840 and we're left with 972.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9720, and continue the process.

Going ahead to step 10:
If we divide 9720 by 978, we get 9 and a remainder of 918.
Record the quotient 9 as the next digit in the result. 
Result so far: 20087.69
Subtract 8802 from 9720 to get 918.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9180, and continue the process.

Step 11:
The number 978 fits into 9180 9 times, leaving a remainder of 378.
Put 9 as the next digit of the answer. 
Result so far: 20087.699
Subtract 8802 from 9180 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final outcome is 20087.699, with a leftover of 0.0378.
