45339239 ÷ 901 
Our goal is to divide 45339239 by 901.

Going ahead to step 1:
If we divide 4 by 901, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 901

Moving on to step 2:
45 divided by 901 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 901

Going ahead to step 3:
901 goes into 453 0 times with a remainder of 453.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 453 to get 453.
Append the next digit (3) from the dividend to 453 and continue with: 4533 / 901

Going ahead to step 4:
901 can be fit into 4533 5 times, resulting in a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 28 after subtracting 4505 from 4533.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 901

On to step 5:
289 divided by 901 is 0 with a remainder of 289.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtract 0 from 289 to get 289.
Fetch the next digit (2) from the dividend, attach it to 289 and continue: 2892 / 901

On to step 6:
The number 901 fits into 2892 3 times, leaving a remainder of 189.
The number 3 becomes the next digit in our result. 
Result so far: 503.0
If we take 2703 away from 2892, we end up with 189.
Append the next digit (3) from the dividend to 189 and continue with: 1893 / 901

On to step 7:
1893 divided by 901 is 2 with a remainder of 91.
Put 2 as the next digit of the answer. 
Result so far: 5032.0
If we take 1802 away from 1893, we end up with 91.
Take the next digit (9) from the dividend and append it to 91, then repeat: 919 / 901

Step 8:
901 goes into 919 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 50321.0
If we take 901 away from 919, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
901 can be fit into 180 0 times, resulting in a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 50321.0
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
The number 901 fits into 1800 1 times, leaving a remainder of 899.
The next digit of our result is 1. 
Result so far: 50321.01
If we subtract 901 from 1800, we get 899.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8990, and continue the process.

Let's proceed to step 11:
901 goes into 8990 9 times with a remainder of 881.
Record the quotient 9 as the next digit in the result. 
Result so far: 50321.019
If we subtract 8109 from 8990, we get 881.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8810, and continue the process.

On to step 12:
901 can be fit into 8810 9 times, resulting in a remainder of 701.
Record the quotient 9 as the next digit in the result. 
Result so far: 50321.0199
Subtracting 8109 from 8810 leaves us with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

In conclusion, the division gives 50321.0199 with a balance of 0.00701.
