We divide 90222030 by 903
We want to divide 90222030 by 903.

Going ahead to step 1:
903 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 903

Moving on to step 2:
903 can be fit into 90 0 times, resulting in 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.
Append the next digit (2) from the dividend to 90 and continue with: 902 / 903

On to step 3:
If we divide 902 by 903, we get 0 and a remainder of 902.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 902 leaves us with 902.
Grab the next digit (2) from the dividend, add it to 902, then carry on: 9022 / 903

Going ahead to step 4:
If we divide 9022 by 903, we get 9 and a remainder of 895.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 895 after subtracting 8127 from 9022.
Take the next digit (2) from the dividend and append it to 895, then repeat: 8952 / 903

On to step 5:
The number 903 fits into 8952 9 times, leaving a remainder of 825.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtracting 8127 from 8952 leaves us with 825.
Bring next digit (0) of the dividend behind the 825 and repeat the process: 8250 / 903

Going ahead to step 6:
903 goes into 8250 9 times with a remainder of 123.
The number 9 becomes the next digit in our result. 
Result so far: 999.0
The remainder is 123 after subtracting 8127 from 8250.
Append the next digit (3) from the dividend to 123 and continue with: 1233 / 903

Step 7:
903 goes into 1233 1 times with a remainder of 330.
Put 1 as the next digit of the answer. 
Result so far: 9991.0
Deduct 903 from 1233 and we're left with 330.
Append the next digit (0) from the dividend to 330 and continue with: 3300 / 903

Going ahead to step 8:
903 goes into 3300 3 times with a remainder of 591.
Write down 3 as next digit of the result. 
Result so far: 99913.0
Subtracting 2709 from 3300 leaves us with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Step 9:
903 can be fit into 5910 6 times, resulting in a remainder of 492.
Use 6 as the next digit of our solution. 
Result so far: 99913.6
Deduct 5418 from 5910 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 10:
When dividing 4920 by 903, we get 5 with a remainder of 405.
The next digit of our result is 5. 
Result so far: 99913.65
The remainder is 405 after subtracting 4515 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 11:
903 can be fit into 4050 4 times, resulting in a remainder of 438.
Put 4 as the next digit of the answer. 
Result so far: 99913.654
If we take 3612 away from 4050, we end up with 438.
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 12:
The number 903 fits into 4380 4 times, leaving a remainder of 768.
The number 4 becomes the next digit in our result. 
Result so far: 99913.6544
Deduct 3612 from 4380 and we're left with 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 quotient of the division is 99913.6544, and the remainder is 0.00768.
