Let's divide 90964381 by 603
Let's see how many times 603 fits into 90964381.

Going ahead to step 1:
The number 603 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 603

On to step 2:
603 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Take the next digit (9) from the dividend and append it to 90, then repeat: 909 / 603

Let's proceed to step 3:
603 can be fit into 909 1 times, resulting in a remainder of 306.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 603 from 909 leaves us with 306.
Take the next digit (6) from the dividend and append it to 306, then repeat: 3066 / 603

Advancing to step 4:
If we divide 3066 by 603, we get 5 and a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 3015 from 3066 and we're left with 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 603

Moving on to step 5:
The number 603 fits into 514 0 times, leaving a remainder of 514.
The next digit of our result is 0. 
Result so far: 150.0
If we take 0 away from 514, we end up with 514.
Take the next digit (3) from the dividend and append it to 514, then repeat: 5143 / 603

On to step 6:
If we divide 5143 by 603, we get 8 and a remainder of 319.
Write down 8 as next digit of the result. 
Result so far: 1508.0
If we take 4824 away from 5143, we end up with 319.
Take the next digit (8) from the dividend and append it to 319, then repeat: 3198 / 603

Advancing to step 7:
The number 603 fits into 3198 5 times, leaving a remainder of 183.
The next digit of our result is 5. 
Result so far: 15085.0
Subtracting 3015 from 3198 leaves us with 183.
Include the next digit (1) from the dividend after 183, then repeat: 1831 / 603

Advancing to step 8:
When dividing 1831 by 603, we get 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 150853.0
The remainder is 22 after subtracting 1809 from 1831.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
The number 603 fits into 220 0 times, leaving a remainder of 220.
The next digit of our result is 0. 
Result so far: 150853.0
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
The number 603 fits into 2200 3 times, leaving a remainder of 391.
The number 3 becomes the next digit in our result. 
Result so far: 150853.03
Deduct 1809 from 2200 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

On to step 11:
The number 603 fits into 3910 6 times, leaving a remainder of 292.
The next digit of our result is 6. 
Result so far: 150853.036
Subtracting 3618 from 3910 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 12:
The number 603 fits into 2920 4 times, leaving a remainder of 508.
Write down 4 as next digit of the result. 
Result so far: 150853.0364
If we take 2412 away from 2920, we end up with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Advancing to step 13:
603 can be fit into 5080 8 times, resulting in a remainder of 256.
The next digit of our result is 8. 
Result so far: 150853.03648
If we take 4824 away from 5080, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 14:
The number 603 fits into 2560 4 times, leaving a remainder of 148.
Write down 4 as next digit of the result. 
Result so far: 150853.036484
Subtracting 2412 from 2560 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 15:
603 goes into 1480 2 times with a remainder of 274.
Record the quotient 2 as the next digit in the result. 
Result so far: 150853.0364842
If we subtract 1206 from 1480, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 16:
2740 divided by 603 is 4 with a remainder of 328.
The next digit of our result is 4. 
Result so far: 150853.03648424
If we subtract 2412 from 2740, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

After the division, we end up with 150853.03648424 and a remainder of 3.28e-07.
