We look at the division of 45456980 by 978 
Let's see how many times 978 fits into 45456980.

Going ahead to step 1:
978 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 978

Moving on to step 2:
The number 978 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 978

Moving on to step 3:
978 can be fit into 454 0 times, resulting in a remainder of 454.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 454, we end up with 454.
Include the next digit (5) from the dividend after 454, then repeat: 4545 / 978

Let's proceed to step 4:
If we divide 4545 by 978, we get 4 and a remainder of 633.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 3912 from 4545 to get 633.
Append the next digit (6) from the dividend to 633 and continue with: 6336 / 978

Let's proceed to step 5:
978 can be fit into 6336 6 times, resulting in a remainder of 468.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtracting 5868 from 6336 leaves us with 468.
Take the next digit (9) from the dividend and append it to 468, then repeat: 4689 / 978

Advancing to step 6:
The number 978 fits into 4689 4 times, leaving a remainder of 777.
Write down 4 as next digit of the result. 
Result so far: 464.0
If we subtract 3912 from 4689, we get 777.
Bring next digit (8) of the dividend behind the 777 and repeat the process: 7778 / 978

Advancing to step 7:
978 goes into 7778 7 times with a remainder of 932.
Use 7 as the next digit of our solution. 
Result so far: 4647.0
Deduct 6846 from 7778 and we're left with 932.
Grab the next digit (0) from the dividend, add it to 932, then carry on: 9320 / 978

Step 8:
978 goes into 9320 9 times with a remainder of 518.
The number 9 becomes the next digit in our result. 
Result so far: 46479.0
Subtracting 8802 from 9320 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

On to step 9:
978 goes into 5180 5 times with a remainder of 290.
Use 5 as the next digit of our solution. 
Result so far: 46479.5
Subtracting 4890 from 5180 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 10:
The number 978 fits into 2900 2 times, leaving a remainder of 944.
The number 2 becomes the next digit in our result. 
Result so far: 46479.52
If we subtract 1956 from 2900, we get 944.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9440, and continue the process.

On to step 11:
978 can be fit into 9440 9 times, resulting in a remainder of 638.
Put 9 as the next digit of the answer. 
Result so far: 46479.529
If we subtract 8802 from 9440, we get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Moving on to step 12:
If we divide 6380 by 978, we get 6 and a remainder of 512.
Put 6 as the next digit of the answer. 
Result so far: 46479.5296
If we subtract 5868 from 6380, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 13:
When dividing 5120 by 978, we get 5 with a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 46479.52965
Subtract 4890 from 5120 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 14:
If we divide 2300 by 978, we get 2 and a remainder of 344.
Put 2 as the next digit of the answer. 
Result so far: 46479.529652
Deduct 1956 from 2300 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 15:
3440 divided by 978 is 3 with a remainder of 506.
The number 3 becomes the next digit in our result. 
Result so far: 46479.5296523
The remainder is 506 after subtracting 2934 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

On to step 16:
If we divide 5060 by 978, we get 5 and a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 46479.52965235
The remainder is 170 after subtracting 4890 from 5060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

After the division, we end up with 46479.52965235 and a remainder of 1.7e-07.
