We look at the division of 18629958 by 900 
We're looking to find how many times 900 goes into 18629958.

Going ahead to step 1:
When dividing 1 by 900, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 900

Let's proceed to step 2:
900 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 900

Moving on to step 3:
186 divided by 900 is 0 with a remainder of 186.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 186 leaves us with 186.
Append the next digit (2) from the dividend to 186 and continue with: 1862 / 900

Step 4:
900 can be fit into 1862 2 times, resulting in a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1800 from 1862 to get 62.
Take the next digit (9) from the dividend and append it to 62, then repeat: 629 / 900

Step 5:
900 goes into 629 0 times with a remainder of 629.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 629, we get 629.
Fetch the next digit (9) from the dividend, attach it to 629 and continue: 6299 / 900

Moving on to step 6:
If we divide 6299 by 900, we get 6 and a remainder of 899.
The next digit of our result is 6. 
Result so far: 206.0
Subtract 5400 from 6299 to get 899.
Append the next digit (5) from the dividend to 899 and continue with: 8995 / 900

Going ahead to step 7:
If we divide 8995 by 900, we get 9 and a remainder of 895.
Record the quotient 9 as the next digit in the result. 
Result so far: 2069.0
If we subtract 8100 from 8995, we get 895.
Fetch the next digit (8) from the dividend, attach it to 895 and continue: 8958 / 900

On to step 8:
The number 900 fits into 8958 9 times, leaving a remainder of 858.
The number 9 becomes the next digit in our result. 
Result so far: 20699.0
The remainder is 858 after subtracting 8100 from 8958.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8580, and continue the process.

On to step 9:
When dividing 8580 by 900, we get 9 with a remainder of 480.
Record the quotient 9 as the next digit in the result. 
Result so far: 20699.9
Subtracting 8100 from 8580 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 10:
900 can be fit into 4800 5 times, resulting in a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 20699.95
Deduct 4500 from 4800 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
The number 900 fits into 3000 3 times, leaving a remainder of 300.
Write down 3 as next digit of the result. 
Result so far: 20699.953
If we subtract 2700 from 3000, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 12:
The number 900 fits into 3000 3 times, leaving a remainder of 300.
Put 3 as the next digit of the answer. 
Result so far: 20699.9533
Deduct 2700 from 3000 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 20699.9533 with a balance of 0.003.
