We divide 90469630 by 623
We want to divide 90469630 by 623.

Moving on to step 1:
9 divided by 623 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 623

Let's proceed to step 2:
623 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Take the next digit (4) from the dividend and append it to 90, then repeat: 904 / 623

On to step 3:
If we divide 904 by 623, we get 1 and a remainder of 281.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 623 from 904 to get 281.
Bring next digit (6) of the dividend behind the 281 and repeat the process: 2816 / 623

Let's proceed to step 4:
623 can be fit into 2816 4 times, resulting in a remainder of 324.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2492 from 2816, we get 324.
Take the next digit (9) from the dividend and append it to 324, then repeat: 3249 / 623

Advancing to step 5:
3249 divided by 623 is 5 with a remainder of 134.
Put 5 as the next digit of the answer. 
Result so far: 145.0
Subtract 3115 from 3249 to get 134.
Append the next digit (6) from the dividend to 134 and continue with: 1346 / 623

Moving on to step 6:
If we divide 1346 by 623, we get 2 and a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 1452.0
Subtract 1246 from 1346 to get 100.
Fetch the next digit (3) from the dividend, attach it to 100 and continue: 1003 / 623

Let's proceed to step 7:
If we divide 1003 by 623, we get 1 and a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 14521.0
If we take 623 away from 1003, we end up with 380.
Bring next digit (0) of the dividend behind the 380 and repeat the process: 3800 / 623

Moving on to step 8:
The number 623 fits into 3800 6 times, leaving a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 145216.0
If we subtract 3738 from 3800, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
When dividing 620 by 623, we get 0 with a remainder of 620.
Put 0 as the next digit of the answer. 
Result so far: 145216.0
If we take 0 away from 620, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 10:
623 can be fit into 6200 9 times, resulting in a remainder of 593.
Use 9 as the next digit of our solution. 
Result so far: 145216.09
If we take 5607 away from 6200, we end up with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Going ahead to step 11:
If we divide 5930 by 623, we get 9 and a remainder of 323.
The next digit of our result is 9. 
Result so far: 145216.099
Deduct 5607 from 5930 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

In conclusion, the division gives 145216.099 with a balance of 0.0323.
