Let's divide 90980564 by 478
Let's see how many times 478 fits into 90980564.

Step 1:
478 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 478

Let's proceed to step 2:
If we divide 90 by 478, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Fetch the next digit (9) from the dividend, attach it to 90 and continue: 909 / 478

Let's proceed to step 3:
If we divide 909 by 478, we get 1 and a remainder of 431.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 478 from 909 and we're left with 431.
Fetch the next digit (8) from the dividend, attach it to 431 and continue: 4318 / 478

Step 4:
The number 478 fits into 4318 9 times, leaving a remainder of 16.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 4302 from 4318 and we're left with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 478

Going ahead to step 5:
478 goes into 160 0 times with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 190.0
Deduct 0 from 160 and we're left with 160.
Fetch the next digit (5) from the dividend, attach it to 160 and continue: 1605 / 478

Moving on to step 6:
1605 divided by 478 is 3 with a remainder of 171.
The number 3 becomes the next digit in our result. 
Result so far: 1903.0
The remainder is 171 after subtracting 1434 from 1605.
Append the next digit (6) from the dividend to 171 and continue with: 1716 / 478

On to step 7:
1716 divided by 478 is 3 with a remainder of 282.
Put 3 as the next digit of the answer. 
Result so far: 19033.0
If we take 1434 away from 1716, we end up with 282.
Bring next digit (4) of the dividend behind the 282 and repeat the process: 2824 / 478

Advancing to step 8:
478 can be fit into 2824 5 times, resulting in a remainder of 434.
Put 5 as the next digit of the answer. 
Result so far: 190335.0
Subtract 2390 from 2824 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 9:
4340 divided by 478 is 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 190335.9
If we take 4302 away from 4340, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
478 can be fit into 380 0 times, resulting in a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 190335.9
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 11:
If we divide 3800 by 478, we get 7 and a remainder of 454.
Put 7 as the next digit of the answer. 
Result so far: 190335.907
Deduct 3346 from 3800 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Going ahead to step 12:
478 can be fit into 4540 9 times, resulting in a remainder of 238.
Use 9 as the next digit of our solution. 
Result so far: 190335.9079
Deduct 4302 from 4540 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 13:
The number 478 fits into 2380 4 times, leaving a remainder of 468.
Record the quotient 4 as the next digit in the result. 
Result so far: 190335.90794
If we take 1912 away from 2380, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 14:
478 can be fit into 4680 9 times, resulting in a remainder of 378.
Write down 9 as next digit of the result. 
Result so far: 190335.907949
Subtracting 4302 from 4680 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 15:
3780 divided by 478 is 7 with a remainder of 434.
The next digit of our result is 7. 
Result so far: 190335.9079497
If we take 3346 away from 3780, we end up with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 16:
478 goes into 4340 9 times with a remainder of 38.
The next digit of our result is 9. 
Result so far: 190335.90794979
If we take 4302 away from 4340, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 190335.90794979, and the remainder is 3.8e-08.
