81052203 divided by 901 
Our goal is to divide 81052203 by 901.

On to step 1:
When dividing 8 by 901, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 901

Step 2:
The number 901 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 901

On to step 3:
The number 901 fits into 810 0 times, leaving a remainder of 810.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 810 to get 810.
Append the next digit (5) from the dividend to 810 and continue with: 8105 / 901

Going ahead to step 4:
901 can be fit into 8105 8 times, resulting in a remainder of 897.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 7208 away from 8105, we end up with 897.
Include the next digit (2) from the dividend after 897, then repeat: 8972 / 901

Advancing to step 5:
901 goes into 8972 9 times with a remainder of 863.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we subtract 8109 from 8972, we get 863.
Bring next digit (2) of the dividend behind the 863 and repeat the process: 8632 / 901

Going ahead to step 6:
The number 901 fits into 8632 9 times, leaving a remainder of 523.
Write down 9 as next digit of the result. 
Result so far: 899.0
The remainder is 523 after subtracting 8109 from 8632.
Include the next digit (0) from the dividend after 523, then repeat: 5230 / 901

Let's proceed to step 7:
If we divide 5230 by 901, we get 5 and a remainder of 725.
Write down 5 as next digit of the result. 
Result so far: 8995.0
Subtract 4505 from 5230 to get 725.
Take the next digit (3) from the dividend and append it to 725, then repeat: 7253 / 901

Let's proceed to step 8:
If we divide 7253 by 901, we get 8 and a remainder of 45.
Use 8 as the next digit of our solution. 
Result so far: 89958.0
Subtract 7208 from 7253 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
901 can be fit into 450 0 times, resulting in a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 89958.0
Deduct 0 from 450 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 10:
If we divide 4500 by 901, we get 4 and a remainder of 896.
Write down 4 as next digit of the result. 
Result so far: 89958.04
The remainder is 896 after subtracting 3604 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8960, and continue the process.

On to step 11:
If we divide 8960 by 901, we get 9 and a remainder of 851.
The next digit of our result is 9. 
Result so far: 89958.049
The remainder is 851 after subtracting 8109 from 8960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Moving on to step 12:
8510 divided by 901 is 9 with a remainder of 401.
Put 9 as the next digit of the answer. 
Result so far: 89958.0499
If we subtract 8109 from 8510, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

In conclusion, the division gives 89958.0499 with a balance of 0.00401.
