We divide 901558 by 2
We want to divide 901558 by 2.

Moving on to step 1:
2 can be fit into 9 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 1 after subtracting 8 from 9.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Moving on to step 2:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 10 from 10, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Let's proceed to step 3:
The number 2 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 450.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Moving on to step 4:
If we divide 15 by 2, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 4507.0
If we subtract 14 from 15, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Going ahead to step 5:
When dividing 15 by 2, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 45077.0
Deduct 14 from 15 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Advancing to step 6:
2 can be fit into 18 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 450779.0
Subtract 18 from 18 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 450779.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 450779.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 450779.0 with a balance of 0.0.
