10661225 ÷ 144 
We want to figure out the number of times 10661225 can be divided by 144.

Going ahead to step 1:
1 divided by 144 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 144

Advancing to step 2:
144 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 144

Going ahead to step 3:
106 divided by 144 is 0 with a remainder of 106.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 106 after subtracting 0 from 106.
Grab the next digit (6) from the dividend, add it to 106, then carry on: 1066 / 144

Step 4:
If we divide 1066 by 144, we get 7 and a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 1008 from 1066 and we're left with 58.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 144

Step 5:
144 can be fit into 581 4 times, resulting in a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
The remainder is 5 after subtracting 576 from 581.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 144

Moving on to step 6:
The number 144 fits into 52 0 times, leaving a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 740.0
The remainder is 52 after subtracting 0 from 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 144

On to step 7:
144 goes into 522 3 times with a remainder of 90.
The next digit of our result is 3. 
Result so far: 7403.0
The remainder is 90 after subtracting 432 from 522.
Fetch the next digit (5) from the dividend, attach it to 90 and continue: 905 / 144

Advancing to step 8:
144 goes into 905 6 times with a remainder of 41.
Write down 6 as next digit of the result. 
Result so far: 74036.0
If we subtract 864 from 905, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
When dividing 410 by 144, we get 2 with a remainder of 122.
The next digit of our result is 2. 
Result so far: 74036.2
If we subtract 288 from 410, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 10:
If we divide 1220 by 144, we get 8 and a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 74036.28
Deduct 1152 from 1220 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
144 can be fit into 680 4 times, resulting in a remainder of 104.
The next digit of our result is 4. 
Result so far: 74036.284
If we subtract 576 from 680, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 12:
144 can be fit into 1040 7 times, resulting in a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 74036.2847
Subtract 1008 from 1040 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
If we divide 320 by 144, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 74036.28472
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
144 goes into 320 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 74036.284722
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 74036.284722 with a remainder of 3.2e-06.
