90011161 divided by 144 
We want to figure out the number of times 90011161 can be divided by 144.

On to step 1:
When dividing 9 by 144, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 144

Step 2:
When dividing 90 by 144, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 144

Advancing to step 3:
144 goes into 900 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 864 from 900 to get 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 144

Let's proceed to step 4:
The number 144 fits into 361 2 times, leaving a remainder of 73.
The next digit of our result is 2. 
Result so far: 62.0
Subtract 288 from 361 to get 73.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 144

Advancing to step 5:
144 goes into 731 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 625.0
If we subtract 720 from 731, we get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 144

Let's proceed to step 6:
When dividing 111 by 144, we get 0 with a remainder of 111.
Put 0 as the next digit of the answer. 
Result so far: 6250.0
Subtract 0 from 111 to get 111.
Include the next digit (6) from the dividend after 111, then repeat: 1116 / 144

Advancing to step 7:
1116 divided by 144 is 7 with a remainder of 108.
Write down 7 as next digit of the result. 
Result so far: 62507.0
The remainder is 108 after subtracting 1008 from 1116.
Bring next digit (1) of the dividend behind the 108 and repeat the process: 1081 / 144

Going ahead to step 8:
144 goes into 1081 7 times with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 625077.0
Subtract 1008 from 1081 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 9:
730 divided by 144 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 625077.5
Subtract 720 from 730 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
144 can be fit into 100 0 times, resulting in a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 625077.5
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
When dividing 1000 by 144, we get 6 with a remainder of 136.
The next digit of our result is 6. 
Result so far: 625077.506
The remainder is 136 after subtracting 864 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 12:
The number 144 fits into 1360 9 times, leaving a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 625077.5069
If we take 1296 away from 1360, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
640 divided by 144 is 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 625077.50694
If we subtract 576 from 640, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
144 can be fit into 640 4 times, resulting in a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 625077.506944
If we subtract 576 from 640, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 625077.506944, and the remainder is 6.4e-06.
